2006-11-09 Scott Dattalo <scott@dattalo.com>
	* doc/gpsim.lyx: Added module documentation, macro documentation,
	scripting documentation, and examples documentation

2006-11-08 Scott Dattalo <scott@dattalo.com>
	* doc/gpsim.lyx: Added module documentation and in particular the
	USART module.

2006-11-08 Borut Razem <borut.razem@siol.net>
	* extras/graphic_lcd/src/glcd_100X32_sed1520.cc,
	  extras/lcd/hd44780.cc, extras/lcd/hd44780.h, extras/lcd/lcd.cc,
	  extras/lcd/lcdgui.cc, extras/lcd/module_manager.cc:
	  removed compiler warnings
	* doc/gpsim.html, doc/gpsim_svn.html: changed encoding to UTF-8
	* plat/win32/gpsim.nsi: changed PRODUCT_WEB_SITE URL and
	  PRODUCT_VERSION

2006-11-08 Scott Dattalo <scott@dattalo.com>
	* src/breakpoints.cc: Fixed compiler warning.

2006-11-08 Borut Razem <borut.razem@siol.net>
	* plat/win32/libgpsim.def: MSVC sync
	* doc/gpsim_svn.html, doc/gpsim.html: doc/gpsim_cvs.html renamed to
	  doc/gpsim_svn.html

2006-11-08 Scott Dattalo <scott@dattalo.com>
	* src/processor.cc: Fixed -p<procname> command line
	option. (actually, there is still an issue with gpsim using the -p
	option to find the processor, but then naming the processor
	something else.)

2006-11-08 Scott Dattalo <scott@dattalo.com>
	* configure.ac: 0.22.0-RC4 - release candidate 4
	* doc/gpsim.html: fix broken links.
	* README, INSTALL: Minor documentation changes pertaining to 0.22.0

2006-11-08 J.R. Heisey <jrheisey@sourceforge.com>
	* cli/cmd_macro.cc:
	- Made some of the macro command console output	conditional
	on the verbose variable to clean up the console output.
	- Enhanced the console output of the cmd_macro::end_define().
	* src/breakpoints.cc: Added call in Breakpoints::set_breakpoint()
	to Processor::NotifyBreakpointSet() to help with the integration
	of processors defined in their own dynamic library.

2006-11-07 Scott Dattalo <scott@dattalo.com>
	* gui/gui_regwin.cc: EEPROM window abort bug fixed on 2006-11-04
	had a flaw. Hopefully that's been fixed now. (The problem was that
	the fix assumed if the maxrow member of the register_sheet was 0
	that there were no cells in the sheet. However, in the gtksheet
	widget, maxrow can be 0 if there's only 1 row!)

2006-11-07 Scott Dattalo <scott@dattalo.com>
	* gui/gui_symbols.cc, gui/gui_src_asm.cc: Changed the way glib
	lists were deallocated. This removes a glib compile warning.

2006-11-07 Scott Dattalo <scott@dattalo.com>
	* src/16bit-registers.h, src/16bit-registers.cc, src/p16x6x.h,
	src/p16x6x.cc, src/p16f87x.h, src/p16f8x.h,
	src/16bit-processors.h, src/16bit-processors.cc, src/p16f62x.h,
	src/p16f62x.cc, src/uart.h, src/uart.cc:
	- Removed USART_MODULE14 and USART_MODULE16 classes. All they were
	doing was declaring a 'cpu' pointer, but they weren't even using
	it.
	- All member functions of the USART_MODULE class are now non-virtual.

2006-11-06 Rob Pearce <rob@bdt-home.demon.co.uk>
	* src/stimuli.cc: Fixed the p12ce51x I2C-EE bug - it was due to a
        stimulus initialisation error caused by bit rot in the node summing
        function for the single stimulus connected case!

2006-11-06 David Barnett <dbarnett@edt.biz>
	* modules/gpsim_modules.cc: The push_button is named as
	"push_button" in push_button.h, but "pushbutton" in
	gpsim_modules.cc.  This had the effect that "module load
	push_button was saved into the netlist file, but "module type
	push_button not created" would display when loading the netlist.

2006-11-06 Scott Dattalo <scott@dattalo.com>
	* doc/gpsim.html, doc/gpsim_cvs.html: Fixed links. Changed CVS
	references to SVN.

2006-11-05 Scott Dattalo <scott@dattalo.com>
	* src/uart.cc, src/uart.h: TXIF is now only gets set if both TXEN
	and SPEN are set. The USART_MODULE class interface was redesigned
	slightly to simplify accesses to the various registers associated
	with the USART.
	* src/p16f62x.cc, src/16bit-registers.cc, src/p16f8x.cc,
	src/16bit-registers.h, src/p16x6x.cc, src/p16f87x.cc,
	src/16bit-processors.cc:
	- Adapted new USART_MODULE interface.
	* regression/usart_test/usart_pir1v1.asm,
	regression/usart_test/usart_pir1v2.asm:
	- The usart regression test noew makes sure that TXIF is not set
	before TXEN and SPEN are set.

2006-11-05 Scott Dattalo <scott@dattalo.com>
	* src/trigger.cc, src/trace.cc, src/breakpoints.cc: Cleaned up
	trace printing of traced breakpoints.

2006-11-04 Borut Razem <borut.razem@siol.net>
	* plat/win32/libgpsim.def: MSVC sync

2006-11-04 Scott Dattalo <scott@dattalo.com>
	* src/cod.cc, src/pic-processor.cc: Applied variation of patch
	submitted by David Barnett <dbarnett@edt.biz> that prepends
	processor name with a 'p' if the name begins with a digit in the
	.cod file

2006-11-04 Scott Dattalo <scott@dattalo.com>
	* gui/gui_breadboard.cc: Patch from Ralf that fixes coordinates of
	components selected in the breadboard.

2006-11-04 Scott Dattalo <scott@dattalo.com>
	* gui/gui_regwin.cc: gpsim was aborting if eeprom window was
	opened while a processor without an eeprom was loaded.
	David Barnett <dbarnett@edt.biz> reported this bug.

2006-11-04 Scott Dattalo <scott@dattalo.com>
	* cli/input.cc: Typo in preprocessor ifdef. This was discovered
	while applying a patch from the Gentoo distro. (The patch had
	already independently been applied, yet the typo hadn't been
	noticed until this new patch had been submitted.)

2006-11-03 Scott Dattalo <scott@dattalo.com>
	* src/trace.cc, src/trace.h, src/dspic/dspic-registers.cc,
	src/12bit-processors.cc, src/processor.cc,
	src/14bit-processors.cc, src/14bit-registers.cc,
	src/16bit-processors.cc, modules/stimuli.cc
	 - TraceType constructors are only initialized with size (and not
	   with type).
	 - Trace entry allocation now gets size request from TraceType
	 class.
	* src/trigger.cc, src/breakpoints.h, src/breakpoints.cc: Trigger
	action implementation for special breakpoints has been enhanced to
	take advantage of multiple trace entries.

2006-11-01 Scott Dattalo <scott@dattalo.com>
	* src/trigger.cc, src/trigger.h, src/breakpoints.h,
	src/breakpoints.cc, src/trace.h, src/trace.cc:
	 - Cleaned up breakpoint tracing.
	 - Added TriggerObject::invokeAction() method to handle the
	 default behavior of invoking a trigger object action and handling
	 the tracing.
	 - Moved the BreakTraceType and BreakTraceObject classes from
	 breakpoints.cc to trigger.cc (probably should rename these?)
	* src/pic-processor.cc: Change the default Integer type output
	width to 2 characters. (At 8 characters, there were a lot of 0's.)
	* src/gpsim_object.cc: toString(char*,int) now returns something.

2006-11-01 Scott Dattalo <scott@dattalo.com>
	* src/breakpoints.cc: Fixed core dump for breakpoint expressions
	that are entered improperly.

2006-11-01 Ralph Neider <rneider@web.de>
	* modules/gpsim_modules.cc: push_buttons are now ignored when
	gpsim is built without the gui.

2006-11-01 Scott Dattalo <scott@dattalo.com>
	* acinclude.m4: Patch from sf user iggie that fixes check for readline 5.2

2006-11-01 Borut Razem <borut.razem@siol.net>
	* plat/win32/libgpsim.def: MSVC sync

2006-11-01 Roy Rankin <rrankin@ihug.com.au>
	* src/pic-processor.cc: Removed p17c7xx processor family from
	  processor list as code does not work

2006-10-31 Scott Dattalo <scott@dattalo.com>
	* src/trace.h, src/trace.cc: TraceType type() now takes an argument
	that allows a user to select a particular subtype.
	* src/trigger.h, src/trigger.cc, src/breakpoints.cc, src/breakpoints.h:
	More breakpoint tracing changes. Execution break points are now
	displayed in the raw trace buffer.

2006-10-28 Scott Dattalo <scott@dattalo.com>
	* src/trace.h, src/trace.cc: Raw trace dumps were cleaned up
	more. The cycle trace is now decoded in a fashion similar to other
	trace types.
	* src/breakpoints.cc: Began design for BreakTraceType and
	BreakTraceObject.

2006-10-30 Roy Rankin <rrankin@ihug.com.au>
	* src/ssp.cc : fixed improper use of type bool
	* regression/p12ce518/p12ce518.asm : correct error in test

2006-10-22 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.nsi: removed doc/*.html, added doc/screenshots/*,
	  added extras\graphic_lcd\doc\*
	* plat/win32/libgpsim.def: MSVC sync
	* gui/gui.vcproj: generate config.h from config_win32.h.in
	* cli/cmd_log.cc, cli.socket.cc, gui/gui_menu.cc, gui/gui_scope.cc,
	  gui/gui_src_asm.cc, modules/led.cc, modules/stimuli.cc,
	  modules/switch.cc, src/12bit-processors.cc, src/14bit-processors.cc,
	  src/16bit-processors.cc, src/comparator.cc, src/p16f8x.cc,
	  src/spp.cc: fixed warning

2006-10-28 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_load.cc: used a different version of the toString()
	method in the load command

2006-10-28 Scott Dattalo <scott@dattalo.com>
	* src/trace.h, src/trace.cc, src/12bit-processors.cc,
	src/14bit-registers.cc:
	 - Added a CycleTraceType
	 - Now trace type classes do not add themselves to the current
	 trace frame whenever their decode() methods are called.

2006-10-25 Scott Dattalo <scott@dattalo.com>
	* gui/gui_src_asm.cc: Source browser page ptr is not ignored when
	symbolic debugging is unavailable.
	* cli/parse.yy: Assigning a non-quoted value to one of the scope
	channel attributes was causing an abort.
	* src/pic-instructions.h, src/14bit-instructions.cc,
	src/pic-instructions.cc, src/16bit-instructions.h,
	src/16bit-instructions.cc:
	  -  Instruction class constructors now initialize all of their
	  data memmbers.
	* doc/gpsim.html: Fixed some missing links.

2006-10-25 Steffen Joeris <Steffen.Joeris@skolelinux.de>
	* modules/paraface.cc: Patch from Debian Etch release that enables
	certain Free BSD builds.

2006-10-24 Scott Dattalo <scott@dattalo.com>
	* src/trace.cc: Added detailed comments on TraceFrames,
	TraceTypes, and TraceObjects.

2006-10-23 David Barnett <dbarnett@edt.biz>
	* src/12bit-processors.cc: Fixed extra qualifier bug in the
	OptionTraceType class.

	* AUTHORS: Added Roy to the list :)
	* regression/Makefile.am: added the i2c regression tests to the
	distribution
	* configure.ac: RC2 - release candidate 2
	* README.EXAMPLES: this was totally out of date and still needs to
	be cleaned up.
	* README: changed revision info, made minor changes.

2006-10-23 Scott Dattalo <scott@dattalo.com>
	* src/14bit-processors.cc, src/12bit-processors.cc,

2006-10-22 Borut Razem <borut.razem@siol.net>
	* */.cvsignore: removed CVS leftovers
	* modules/stimuli.cc: trace.* replaced with get_trace().*
	  the getter function instead of direct object access should
	  be used in modules
	* plat/win32/sdcc.nsi: added examples/modules/*/README to the
	  setup package

2006-10-19 Scott Dattalo <scott@dattalo.com>
	* regression/Makefile.am: Added
	* configure.ac, extras/graphic_lcd/configure.ac, Makefile.am,
	examples/Makefile.am: Changed revision from 0.21.12-pre to
	0.22.0-RC1.

2006-10-18 Scott Dattalo <scott@dattalo.com>
	* src/processor.cc, src/processor.h:
	 - insertRegister() and removeRegister() methods of the
	 RegisterMemoryAccess class now return bool.
	* src/breakpoints.cc: deleted commented out code.
	* modules/stimuli.cc, modules/stimuli.h: Implemented the register
	 mapping functionality.
	* cli/parse.yy: improved the reg() operator syntax. It used to be
	 that only integer operands were accepted. Now, expressions are
	 accepted.
	* regression/port_stim/18f452.lkr: added
	* regression/port_stim/Makefile: added
	* regression/port_stim/port_stim.stc: added
	* regression/port_stim/port_stim.asm: added
	* regression/run_regression.sh: Added a regression test for the
	 port_stimulus module.

2006-10-17 Scott Dattalo <scott@dattalo.com>
	* examples/projects/stack_test/stack_test.asm,
	examples/projects/stack_test/stack_test.stc,
	examples/projects/stack_test/Makefile,
	examples/projects/digital_stim/digital_stim.stc,

	 - Clean up examples.
	* configure.ac: Removed the 12bit, 14bit, and 16bit subdirectories
	from the list of packaged directories. The example code there is old and
	needs a whole lot of work to get working.

2006-10-17 Scott Dattalo <scott@dattalo.com>
	* examples/modules/Makefile.am,
	examples/modules/usart_test/usart_test.asm,

	* examples/modules/usart_test/usart.asm: removed


2006-10-17 Scott Dattalo <scott@dattalo.com>
	* src/ssp.cc: Fixed uninitialized class data.

2006-10-17 Scott Dattalo <scott@dattalo.com>
	* src/breakpoints.h, src/breakpoints.cc, src/processor.h,
	src/processor.cc, src/registers.cc, src/registers.h:
	Moved the register breakpoint clearing and setting functionality
	from the register breakpoint classes to the
	RegisterMemoryAccess. The purpose of this is to allow other types
	of register objects (besides break points) to replace registers.
	* modules/gpsim_modules.cc, modules/stimuli.cc, modules/stimuli.h:
	Added the parallel port stimulus. This stimulus is identical to a
	PIC port register in that it has a PORT, TRIS, and LATCH
	register. Users can control the state of the parallel port
	stimulus in one of two ways. First, there are user accessible
	attributes (eg port.latch can be assigned a value). Second, (and
	this is not completed yet) the user can embed the parallel
	stimulus into the register memory map. This allows the parallel
	stimulus to be accessed programmatically (that is from within the
	PIC assembly code). This allows an assembly program to directly
	control the simulation environment.


2006-10-17 Scott Dattalo <scott@dattalo.com>
	* src/trace.cc, src/trace.h: Changed an empty trace entry from 0
	to 0x3fffffff. This provides away to differentiate between an
	empty trace entry and an uninitialized trace type.

2006-10-17 Scott Dattalo <scott@dattalo.com>
	* src/pic-ioports.h, src/pic-ioports.cc, src/16bit-processors.cc,
	src/16bit-processors.h: Moved the PicLatchRegister class from the
	16bit-processor definitions to the pic-ioport definitions.

2006-10-16 Scott Dattalo <scott@dattalo.com>
	* gui/gui_src_asm.cc: Renamed the popup menu item function 'Run
	here' to 'Run to here'.

2006-10-15 Scott Dattalo <scott@dattalo.com>
	* gui/gui_src_asm.cc: The popup menu item function 'Move PC here'
	was not updating the program counter.

2006-10-15 Scott Dattalo <scott@dattalo.com>
	* src/trace.h, src/trace.cc:
	  - Added classes for tracing module events.
	  - Fixed a couple of bugs with invalid trace objects being
	  created. Also, invalid trace entries were causing the trace dump
	  to be aborted.
	* src/16bit-instructions.cc: Removed commented out code
	* src/dspic/dspic-processors.cc, src/processor.h,
	  src/pic-processor.cc, src/registers.cc, src/ioports.cc,
	  src/processor.cc, src/14bit-registers.cc, src/registers.h:
	  The interface to the trace buffer changed slightly. Also,
	  registers were improperly allocating trace objects.
	* doc/gpsim.lyx: Added some more documentation.

2006-10-08 Scott Dattalo <scott@dattalo.com>
	* modules/switch.cc, modules/switch.h: separated out the gui
	specific portions of the switch into another class.

2006-10-04 Scott Dattalo <scott@dattalo.com>
	* modules/switch.cc: Switch resistance has successfully been reintroduced
	* regression/switch_test/switch_test.asm: Added a test to test the
	switch resistance. Note, there are no assertions set on the test
	because currently there is no way to query the node voltage
	directly.

2006-10-02 Borut Razem <borut.razem@siol.net>
	* gpsim.sln, cli/input.cc, cli/cli.vcproj, cli/makefile.mingw,
	  gpsim/gpsim.vcproj, gpsim/makefile.mingw, plat/win32/gpsim.nsi:
	  use readline 5.1. Packages are available at
	  http://gpsim.sourceforge.net/gpsimWin32/packages/readline-5.1-20061001-src.zip,
	  http://gpsim.sourceforge.net/gpsimWin32/packages/readline-5.1-20061001-lib.zip,
	  http://gpsim.sourceforge.net/gpsimWin32/packages/readline-5.1-20061001-bin.zip
	* doc/gpsimwin32.html: readline 5.1

2006-09-29 Scott Dattalo <scott@dattalo.com>
	* modules/switch.cc, modules/switch.h: Trying to reintroduce
	switch on resistance.
	* modules/gpsim_modules.cc, modules/resistor.cc,
	modules/resistor.h: minor clean ups
	* regression/switch_test/switch_test.asm: Additional
	comments. Tried to add a test to test switch on resistance...

2006-09-25 Borut Razem <borut.razem@siol.net>
	* src/sdc.vcproj, src/makefile.mingw: added pm_rd.* to the project

2006-09-21 Dave Barnett <dbarnett@edt.biz>
	* src/pm_rd.cc, src/pm_rd.h: Support for midrange device's program
	memory read feature.
	* p16x7x.cc, src/p16x7x.h, src/pic-processor.cc,
	src/pic-processor.h, src/Makefile.am:
	Added support for the P16F73 and P16F74
	* src/ssp.cc: Fixed typo in printf statement

2006-09-19 Scott Dattalo <scott@dattalo.com>
	* src/pic-processor.cc, src/p16f62x.cc, src/p16f62x.h: Added the
	p16f624 and the p16f624a

2006-09-19 Scott Dattalo <scott@dattalo.com>
	* src/pic-processor.cc, regression/p16f628/p16f628.asm: Added the
	p16f627a and p16f628a processors. Note that these are identical to
	the non-A versions.

2006-09-10 J.R. Heisey <jrheisey@sourceforge.com>
	* src/ValueCollections.h: Added indexing operator to class
	IIndexedCollection.
	* src/sim_context.cc,h: Added function CSimulationContext::
	GetCycleCounter().
	* src/modules.cc,h : Added functions to class ModuleLibrary:
	GetLibraryFileHandle() and GetLibraryFunction().
	* gui/gui_src_asm.cc, gui/gui_src.h:
	- Rescoped several functions into classes to help me keep track
	of their context. Especially the callbacks.
	- Implemented the popup menu items: Settings, Find PC, Move PC here,
	Run here, Breakpoint here, Profile start here, Profile stop here,
	and most importantly Add to Watch.
	- Note that the Font selection dialog doesn't seems to actually
	change the font. It appears to be the same with the old
	GUI. I haven't checked into it.
	- Changed the font selection dialog and the settings dialog
	to use the gtk_dialog_run() function. This fixed an issue
	when the close (upper right X) button was used the underlying
	window would be deallocated. This caused the window to never
	appear again requiring restarting gpsim.

2006-09-03 Scott Dattalo <scott@dattalo.com>
	* gui/gui_scope.cc, gui/gui_scope.h: Signal name editing now works.
	Screen updates for signal names have been fixed.

2006-09-03 Borut Razem <borut.razem@siol.net>
	* doc/gpsimWin32: glib-2.12.1, gtk+-2.8.20, cairo-1.2.2

2006-08-27 Scott Dattalo <scott@dattalo.com>
	* gui/gui_scope.cc, gui/gui_scope.h:
	- Time axis is now shown. Major and Minor tick marks and the
	corresponding grid lines are drawn.

2006-08-21 Scott Dattalo <scott@dattalo.com>
	* gui/gui.h: KeyEvent now differentiates presses and releases.
	* gui/gui_src.cc: Update KeyEvent objects.
	* gui/gui_scope.cc, gui/gui_scope.h: Numerous enhancements:
	  - Added support for markers
	  - Wave pixmaps are now 1024 pixels wide. This primarily fixes a
	  round off error in the binary search routine
	  - Scroll thumb now adjust size based on amount of waveform
	  plotted
	  - Hot key functionality:
	    z -- Zoom in
	    Z -- Zoom out
	    r -- pan right
	    l -- (lowercase ell) pan left
	  - Glitches are now plotted
	  - High frequency events (i.e. events for which there is
	  inadequate monitor resolution to completely show) are plotted in
	  a different color.
	  - Reomved the Pane widget - it was holding the waveforms and
	  just eating up space.
	  - Added WaveBase in anticipation of different types of
	  waveforms.
	* src/bitlog.h, src/bitlog.cc: The ThreeStateLogger can now return
	the number of events occurring between two time intervals or
	between two event indices. (Used for high frequency measuring).

2006-08-08 Scott Dattalo <scott@dattalo.com>
	* gui/gui_main.cc: Now scope window is updated when simulation
	stops.
	* gui/gui_src_asm.cc: Refresh gui menu when src window changes
	hidden state.
	* gui/gui_scope.cc: Redesigned scope window layout. Adding
	scrolling.

	- Serial Peripheral Interface (SPI)

2006-07-31 Scott Dattalo <scott@dattalo.com>
	* src/pic-ioports.cc: RBIF was not handled correctly when the
	change on interrupt was due to a write to PORTB.
	* regression/interrupts_14bit.asm: Add a check for the RBIF flag
	getting set correctly.
	* arc/p16x8x.cc: W was not getting added to the symbol table.

2006-07-30 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_log.cc: Cleaned up help description.

2006-07-30 Scott Dattalo <scott@dattalo.com>
	* cli/parse.yy, cli/cmd_log.h, cli/cmd_break.cc, cli/cmd_break.h,
	  cli/cmd_log.cc, src/gpsim_object.cc, src/value.h, src/value.cc,

	  src/registers.h, src/breakpoints.h, src/breakpoints.cc,
	  src/symbol.h, src/gpsim_object.h, src/operator.cc, src/operator.h,
	  src/symbol.cc:
	- Fixed logging. The logging feature has been broken for a long
	  time. The old code that performed logging has been mostly
	  removed. The new logging code is similar to the breakpoint
	  code. It  utilizes TriggerActions.to perform the logging
	  operations.
	- (The profiling feature is currently broken too. However, it
	  should be possible to utilize TriggerActions for profiling).

2006-07-30 Scott Dattalo <scott@dattalo.com>
	* gui/gui_scope.cc, gui/gui_scope.h: development snap - still not
	complete

2006-07-29 Borut Razem <borut.razem@siol.net>
	* cli/cli.vcproj, gpsim/gpsim.vcproj, gui/gui.vcproj,
	  modules/modules.vcproj: added cairo dependency, clening
	* plat/win32/libgpsim.def: MSVC sync
	* src/i2c-ee.c, modules/i2c-eeprom.c: removed compiler warnings

2006-07-26 Roy Rankin <rrankin@ihug.com.au>
	*  src/i2c-ee.h src/i2c-ee.cc modules/i2c-eeprom.cc
	   modules/i2c-eeprom.h modules/gpsim_modules.cc:
	- Added I2C EEprom modules for 24xx024, 24xx16b, 24xx256

2006-07-24 Borut Razem <borut.razem@siol.net>
	* cli/makefile.mingw, cli/cli.vcproj: define HAVE_SOCKETS -
	  sockets are enabled on WIN32
	* plat/win32/libgpsim.def, src/src.vcproj: MSVC sync
	* doc/gpsimWin32: glib-2.10.3, gtk+-2.8.18, pango-1.12.3

2006-07-23 Scott Dattalo <scott@dattalo.com>
	* cli/socket.cc: Re-enabled the socket interface.
	* examples/scripts/makefile: Hmm, for some reason pango is now
	required to build the examples.

2006-07-22 Rob Pearce <rob@bdt-home.demon.co.uk>
	* src/Makefile.am
	  Added a2dconverter.h to the headers list, so that it's included
	  in the tarball built by make dist

2006-07-14 Roy Rankin <rrankin@ihug.com.au>
	* src/p18x.h src/p18x.cc src/pic-instructions.cc
	  src/pic-processor.cc src/pic-processor.h:
	- P18F248 now based on P18F242, P18F448 added based on P18F424
	* src/p16x6x.cc: remove debug output

2006-07-12 Scott Dattalo <scott@dattalo.com>
	* cli/parse.yy, cli/input.cc: Previously, the parser would abort
	parsing upon detection of syntax errors. Now the parser will only
	ignore the erroneous lines. The difference mainly applies to scripts.

2006-07-11 Scott Dattalo <scott@dattalo.com>
	* gui/gui_scope.h, gui/gui_scope.cc: Added scope.zoom and
	scope.pan attributes that allow the image in the scope window to
	be panned and zoomed.
	* src/makefile.mingw: added the new psp.cc file.

2006-07-11 Roy Rankin <rrankin@ihug.com.au>
	* src/p16x6x.h src/p18x.h src/p16x6x.cc src/pic-ioports.h

	  regression/psp/p18f452.asm regression/psp/p16f871.asm
	  regression/psp/Makefile regression/run_regression.sh:
	- Add PSP functionality to 40 pin processors based on P16C64 & P18C4x2

2006-07-08 Scott Dattalo <scott@dattalo.com>
	* makefile.mingw, plat/win32/make.mingw: Created a 'make depend'
	rule for the win32 makefiles. Here's how it works; first create
	the dependency file:
	$ make -f makefile.mingw depend
	This will create a file named 'mf' in each directory. Now gpsim
	can be built by:
	$ make -f mf
	(Note: There is a bug with make depend in the modules directory).

2006-07-08 Scott Dattalo <scott@dattalo.com>
	* gui/gui_scope.cc, gui/gui_scope.h, gui/gui.h, gui/gui_src.cc:
	- Moved the KeyEvent class definition to gui.h.
	- Moved gui_scope local declarations to Scope_Window class.

2006-07-07 Scott Dattalo <scott@dattalo.com>
	* gui/gui_scope.cc: Added a GtkEntry widget to hold scope signal
	names. Now signals can be specified either through the GtkEntry or
	by the command line attributes.

2006-07-06 Scott Dattalo <scott@dattalo.com>
	* gui/gui_scope.cc: IOPINs can now be attached to scope
	channels. The attachment can only be made at the command line:
	 gpsim> scope.ch0="porta0"
	Everytime the state of porta0 is changed, the event will also be
	sent to the scope window where it will get logged and
	displayed. (Note, the quotes are necessary to prevent gpsim from
	evaluating the pin name.)
	* regression/logic_test/logic_test.asm: The logic OR gates
	connected to porta0,porta1,porta2,portc0 are now displayed in the
	scope window.

2006-07-05 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.h, src/stimuli.cc: Added a virtual destructor to the
	PinMonitor class.
	* src/16bit-processors.h, src/16bit-processors.cc,
	src/pic-ioports.cc, src/processor.cc, src/gpsim_object.cc: minor
	changes to remove compiler warnings.
	* gpsim/CopyDlls.bat: This bat file copies the DLLs for the win32
	builds to the gpsim/gpsim. A few more DLLs were added to the list.

2006-07-05 Scott Dattalo <scott@dattalo.com>
	* plat/win32/make.mingw: Added an option to use ccache for mingw
	builds. Unfortunately, for this to work well the makefile
	dependencies also need to be implemented correctly.

2006-07-04 Roy Rankin <rrankin@ihug.com.au>
	* src/p16x6x.h src/p16x6x.cc src/p16f87x.cc src/p16f87x.h
	  src/pir.cc src/pir.h src/comparator.h src/a2dconverter.h
	  src/comparator.cc regression/comparator/compar_877a.asm:
	- Fixes involving PIR_SET

2006-07-03 Borut Razem <borut.razem@siol.net>
	* cli/cli.vcproj, src/src.vcproj, src/makefile.mingw,
	  plat/uxtime.cc, plat/uxsleep.cc, plat/uxtime.h: uxtime.cc splitted
	  to uxtime.cc and uxsleep.cc, since gettimeofday() is now declared
	  in mingw

2006-07-01 Scott Dattalo <scott@dattalo.com>
	* gui/gui_menu.cc, gui/gui_scope.cc, gui/gui_processor.cc,
	  gui/gui_main.cc:
	  - resurrected the scope window.
	  - ThreeStateEventLogger logs traced states.
	  - Implemented an efficient bisecting algorithm for mapping
	    events states onto the plotting window.
	  - Created attributes:
	    scope.ch0 - scope.ch7 specify nodes that are to be monitored
	    scope.start and scope.stop specify the range of time to be
	    viewed.
	  Currently, the scope window cannot display real data. Instead,
	  it will synthesize test data. The scope.start and scope.stop
	  attributes do work.
	* src/ioports.h, src/stimuli.h, src/stimuli.cc, src/ioports.cc:
	  - Moved the SignalSink class to stimuli.h
	  - Introduced addSink and removeSink methods to the PinMonitor
	    class.
	  - Removed references to 'OLD_IOPORT_DESIGN'
	* src/bitlog.cc, src/bitlog.h: The ThreeStateEventLogger class now
	  has a flag to indicate when the event buffer is
	  empty. Previously, a "bogus" time was placed at position 0,
	  however this broke the logic that searches for events at
	  particular times.
	* src/symbol.cc: Added a debug message.

2006-07-01 Scott Dattalo <scott@dattalo.com>
	* cli/Makefile.am: Applied patch 1470810 which adds the readline
	library to list of libraries linked with the cli library.

2006-06-22 Borut Razem <borut.razem@siol.net>
	* extras/usart_con/*: removed from svn
	* makefile.mingw, plat/win32/gpsim.nsi: removed usart_con
	* modules/usart.cc, modules/usart.cc: added possibility to write to
	  the console using the boolean attribute "console = true | false"
	* examples/modules/usart_gui/usart_gui.asm: send only '\n' for the
	  newline, introduced putchar procedure, ...

2006-06-21 Roy Rankin <rrankin@ihug.com.au>
	* regression/usart_test/usart_pir1v1.asm,
	  regression/usart_test/usart_pir1v2.asm:
	- Check PIC TX pin is high when first set to output.
	* src/pic-ioports.cc: Portb, allow driving state to be set
	  even when bit is set.
	* src/tmr0.cc: Fix call of clear_break.

2006-06-16 Scott Dattalo <scott@dattalo.com>
	* src/14bit-tmrs.h, src/14bit-tmrs.cc: TMR2 wasn't getting
	properly initialized when the TMR2ON bit in T2CON was getting set.
	* TODO: Removed the "Source Browser Search" todo item

2006-06-13 Borut Razem <borut.razem@siol.net>
	* CVSROOT: removed the CVS left-over
	* extras/usart_con/usart_con.cc: print control characters in <%02X>
	  format
	* gui/gui_src_asm.cc: added strcasestr() function

2006-06-16 Scott Dattalo <scott@dattalo.com>
	* TODO: Cleaned up the TODO list.
	* gui/gui_src_asm.cc, gui/gui_src.h: Implemented the Source
	Browser "Find" dialog box. When the new source browser had been
	re-written, this feature was ommitted. The dialog supports forward
	and backward searches and case sensitivity. The search history
	feature is not currently working (was it ever?). Also, it'd be
	useful to have a "search all files" feature.
	* gui/gui_menu.cc: Minor change to TextStyle API.

2006-06-13 Scott Dattalo <scott@dattalo.com>
	* src/sim_context.cc, cli/input.cc, cli/cmd_load.cc: Rewrote code
	to get around a gcc 3.2.2 x86 bug regarding the mis-handling of
	const char * types (the ECX register was getting clobbered!).

2006-06-13 Borut Razem <borut.razem@siol.net>
	* src/os_dependent.c, src/modules.h, src/modules.cc:
	  reverted cahanges for fix:
	  [ 1488107 ] const violation in get_error_message()
	  since dlerror() returns const char * on FreeBSD
	* pic_processor.h: fixed warning
	  multiple default constructors specified
	* plat/win32/libgpsim.def: MSVC sync
	* doc/gpsimWin32.html: patched gtk+extra-2.1.1-src-20060611.zip

2006-06-12 Roy Rankin <rrankin@ihug.com.au>
	* regression/usart_test/usart_pir1v1.asm
	  regression/usart_test/16f628.lkr
	  regression/usart_test/usart_pir1v2.asm
	  regression/usart_test/Makefile regression/run_regression.sh:
	- Improve USART regression tests
	* regression/usart_test/usart_test.stc
	  regression/usart_test/usart_test.asm: removed as redundant
	* src/uart.cc src/uart.h: receive baud rate fix
	* modules/usart.cc modules/usart.h: Transmit baudrate fix,
	  loop attribute added, receiver rewritten to remove event logger.

2006-06-10 Robert Pearce <rob@bdt-home.demon.co.uk>
	* doc/gpsim.lyx: Some hacked notes on creating new modules, and a few
	 other tweaks

2006-06-10 Roy Rankin <rrankin@ihug.com.au>
	* src/gpsim_time.h src/stimuli.cc src/gpsim_time.cc src/processor.cc
	  src/14bit-registers.cc: cycles_per_second changed to instruction_cps
	* src/cod.cc: prevent duplicate symbol messages from static .cod file
	  by not loading constants
	* gui/gui_stopwatch.cc: remove magic number, Frequency format change
	* src/pir.cc src/pir.h: RCIF not being set by uart
	* src/uart.cc modules/usart.cc: fix baud rate error

2006-06-03 Scott Dattalo <scott@dattalo.com>
	* src/16bit-processors.cc: The newly added config words were
	  placed at word addresses instead of byte addresses.
	* src/pic-instructions.cc: Removed warning in CLRWDT instruction
	  that said 16bit wdt timer is not implemented.
	* src/hexutils.cc: removed ifdef'd out code

2006-06-03 Scott Dattalo <scott@dattalo.com>
	* cli/parse.yy, cli/input.cc, cli/input.h, cli/cmd_load.cc:
	  Added an option to the load command to allow processors to be
	  named. Eg:

	  gpsim> load test.cod U1   # Assign U1 ref. des. to processor

	* src/processor.h, processor.cc,
	  src/p16x6x.h, src/p16x6x.cc,
	  src/p16f87x.h, src/p16f87x.cc,
	  src/16bit-processors.h, src/16bit-processors.cc,
	  src/pic-processor.h, src/pic-processor.cc,
	  src/p16f62x.h, src/p16f62x.cc,

	  src/14bit-processors.h,src/14bit-processors.cc,
	  src/dspic/dspic-processors.cc, src/dspic/dspic-processors.h:

	Pic processors now can be named when instantiated.

	* gui/gui_menu.cc: Adhere to the new calling convention for gpsim_open.

	* src/hextutils.h, src/hexutils.cc, src/program_files.cc, src/program_files.h,
	  src/sim_context.h, src/sim_context.cc, src/cod.cc: New
	calling convention for LoadProgramFile

	* src/os_dependent.cc: There appeared to be a compiler bug
	IsFileExtension() (a const pointer in the callee's stack space was
	getting modified). But, there is a built in STL function that does
	the same thing IsFileExtension() was doing, so that's now used.

	* regression/ttl/ttl377.stc: added
	* regression/ttl/Makefile, regression/comparator/compar_877a.stc,
	  regression/comparator/compar_628.stc,
	  regression/comparator/compar_873a.stc,
	  regression/p16f84/p16f84.stc,
	  regression/switch_test/switch_test.stc,
	  regression/switch_test/switch_test.asm,

2006-06-03 Roy Rankin <rrankin@ihug.com.au>
	* src/stimuli.cc, src/stimuli.h: New resistor-capacitor transient
	  voltage calculation implemented and activated, getBitChar function
	  re-written.
	* modules/switch.cc, modules/switch.h,
	  regression/switch_test/switch_test.asm:
	- Switch module model changed eliminating Rclosed parameter

2006-03-02 Borut Razem <borut.razem@siol.net>
	* extras/graphic_lcd/makefile.mingw, plat/win32/gpsim.nsi:
	  graphic_lcd.dll renamed to libgpsim_graphicLCD.dll
	* extras/lcd/examples/lcd_mod.stc:
	  libgpsim_lcd.so changed to libgpsim_lcd

2006-05-31 Scott Dattalo <scott@dattalo.com>
	* src/p16x6x.h, src/16bit-processors.cc, src/14bit-registers.h,
	  src/processor.h, src/pic-registers.h, src/pic-processor.cc,
	  src/pic-processor.h, src/p16x8x.h, src/pic-registers.cc,
	  src/breakpoints.cc, src/12bit-processors.h,
	  src/14bit-processors.cc, src/14bit-processors.h:

	Accesses to CONFIG2H now can control the WDT. A couple of new
	members were added to the WDT class to support the new reading and
	writing. Also, some minor class clean up was also performed.

2006-05-31 Borut Razem <borut.razem@siol.net>
	* Implemented enhancement request
	  [ 1496325 ] To bundle the extra modules with gpsim-win32 snapshot
	  makefile.mingw: added targets extras, clean_extras
	  extras/graphic_lcd/makefile.mingw, extras/lcd/makefile.mingw,
	  extras/usart_com/makefile.mingw: introduced GPSIM_LIB_PATH,
	  GPSIM_INCLUDE_PATH, GPSIM_DEF_PATH variables
	  plat/win32/gpsim.nsi: added potion to install extras modules

2006-05-28 Borut Razem <borut.razem@siol.net>
	* src/os_dependent.c, src/modules.h, src/modules.cc,
	  src/sim_context.cc:
	  fixed [ 1488107 ] const violation in get_error_message()

2006-05-29 Robert Pearce <rob@bdt-home.demon.co.uk>
	* regression/resistor/resistor.asm: improved failure reporting
	  and added tests for the output pin not being swamped
	* src/stimuli.cc, src/stimuli.h: Adjusted default Zth values to
	  be more sensible (ZthWeak now > ZthPullUp). Also some debug
	  messages on wht looks like a dodgy condition. Need to follow up.
	* doc/gpsim.lyx: corrected some formatting.

2006-05-28 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.nsi: removed unneeded asprintf.dll from
	  the package, added possibility to define the SETUP_DIR from
	  the NSIS command line
	* doc/gpsimWin32.html: glib-2.8.6, gtk+-2.8.17, pango-1.12.1,
	  cairo-1.0.4
	* extras/graphic_lcd/src/gpsim_modules.cc,
	  extras/graphic_lcd/src/sed1520.cc,
	  extras/lcd/hd44780.cc: removed unneeded inclusion of config.h
	* extras/graphic_lcd/makefile.mingw: added, thanks to Xiaofan Chen
	* extras/lcd/makefile.mingw: corrected, thanks to Xiaofan Chen
	* makefile.mingw: added rules doc and setup
	* plat/win32/fd2raw.cpp: report error messages

2006-05-28 Roy Rankin <rrankin@ihug.com.au>
	* src/gpsim_object.cc: Improve GNU demangling
	* modules/switch.cc, modules/switch.h,
	  regression/switch_test/switch_test.asm:
	- Fix infinite regression bug.

2006-05-27 Scott Dattalo <scott@dattalo.com>
	* src/ValueCollections.cc, src/ValueCollections.h,
	src/14bit-registers.cc: An indexed collection can now accommodate
	a disjoint set.
	* src/16bit-processors.h, src/16bit-processors.cc,
	src/dspic/dspic-processors.cc, src/dspic/dspic-processors.h,
	src/processor.h, src/processor.cc, src/pic-processor.h,
	src/14bit-processors.h,src/14bit-processors.cc,
	src/pic-processor.cc: The ProgramMemoryClass now uses the newly
	added "disjoint set" feature of an IndexedCollection to provide
	access to configuration memory. E.g.

	  romData[0x300000] = 0x1234

	will write 0x1234 to the configuration word at address 0x300000.
	In addition, infrastructure has been added to symbolically deal
	with configuration memory. E.g.

	  gpsim> .CONFIG1H
	  $00000027

	  gpsim> help .CONFIG2H
	  $0000000f
	  WatchDog configuration

	Currently the configuration memory does not control any
	thing. I.e., if you write to config memory, the data changes, but
	the processor configuration is not actually changed.

	* src/hexutils.cc: removed printf debugging.

2006-05-25 Scott Dattalo <scott@dattalo.com>
	* modules/stimuli.h, modules/stimuli.cc: More support for
	  file stimulus.

2006-05-25 Scott Dattalo <scott@dattalo.com>
	* modules/logic.h, modules/logic.cc, modules/gpsim_modules.cc:
	Only use if the gui is enabled

2006-05-25 Scott Dattalo <scott@dattalo.com>
	* modules/switch.h, modules/switch.cc, modules/gpsim_modules.cc:
	  Only use gui if enabled.
	* modules/stimuli.h, modules/stimuli.cc: Began adding support for
	  file stimulus.

2006-05-24 Borut Razem <borut.razem@siol.net>
	* modules/makefile.mingw, modules/modules.vcproj: added stimuli.*
	* plat/win32/libgpsim: MSVC sync

2006-05-23 Borut Razem <borut.razem@siol.net>
	* doc/gpsimWin32.html: CVS replaced with Subversion

	* src/14bit-tmrs.h, src/14bit-tmrs.cc:
	- PWM fixes CCP high if duty cycle 0, CCPRnH loaded on TMR2
	  compare, PWM starts after first TMR2 compare, PMR2::put
	  and PR2::put rewrite
	* regression/ccp/pwm_877a.asm, regression/ccp/Makefile,
	  regression/run_regression.sh: PWM regression

2006-05-21 Scott Dattalo <scott@dattalo.com>
	* modules/stimuli.h, modules/stimuli.cc: New files for 'extended'
	stimuli. Currently only an asynchronous stimulus replacement
	called 'pulsegen' has been created.

	the default list of modules.
	* regression/run_regression.sh, regression/wavegen/16f877a.lkr,
	regression/wavegen/Makefile, regression/wavegen/pulsegen.asm,
	regression/wavegen/pulsegen.stc: New regression test to test the
	pulsegen module. (This test is really just a copy of the ccp
	regression test except that the asynchronous stimulus has been
	replaced with a pulsegen module).
	* src/symbol.cc: Module symbol descriptions were not getting
	printed
	* cli/cmd_break.cc: removed bogus warning about cycle break points
	not getting set.

2006-05-21 Robert Pearce <rob@bdt-home.demon.co.uk>
	* src/p16f87x.h, src/p16f87x.cc: Re-worked 16F871 to be derived from
	  16C64 rather than 74, because that's the easiest way I could find to
	  fix the RAM size (it had way too much) and the stray CCP2

2006-05-19 Scott Dattalo <scott@dattalo.com>
	* src/expr.h, src/expr.cc: Added LiteralArray class for (better)
	  handling array types.
	* cli/parse.yy, cli/scan.ll: experimenting with user-created typed
	  symbols.
	* src/processor.cc: Removed bogus check that prevented users from
	  over-writing the Rom contents. If the user wants to over write
	  ROM then they should be allow to!

2006-05-19 Roy Rankin <rrankin@ihug.com.au>
	* src/14bit-tmrs.cc: TMR2 counts down not up, period wrong,
	  fix 2 PWM with same duty cycle

	  gui/gui_breadboard.cc: Allow pin names to be changed after breadboard
	  is started.
	* src/stimuli.cc: minor output format change and new debuging output

2006-04-22 Roy Rankin <rrankin@ihug.com.au>

	for the 16c71.

2006-04-13 Borut Razem <borut.razem@siol.net>
	* gui/gui_src_asm.cc: removed warnings

	Files.
	* src/p16f87x.cc, src/p16x7x.h, src/p16x7x.cc:  Removed
	a2d-specific stuff from p16x7x.[h,cc] and placed it into
	a2dconverter.[h,cc].
	Also, the p16c71 doesn't have a PIR register. The INTCON class
	assumes that there is one. So a special (non-existant) PIR
	register has been created that is not instantiated in the register
	map, but is capable of communicating PIR-specific information with
	those peripherals that implement their own PIR functionality (this
	is currently only the P16C71 A2D module).
	* src/pir.h: The PIR_SET used to be a pure virtual base
	class. This class needs to be redesigned...
	* src/pir.h: Made class members private.
	* src/gpsim_object.h, src/gpsim_object.cc, src/value.h,
	src/value.cc: Moved Value descriptions into the parent gpsimObject
	class. The purpose of this change is to provide a uniform way in
	which gpsimObjects (like processors and modules) can describe
	themselves.

	* modules/resistor.cc: Added a voltage attribute to pull up
	resistors. Now pullup resistors can be used as general purpose
	voltage sources.

	causing segv's

2006-04-11 Scott Dattalo <scott@dattalo.com>
	* gui/gui_src.h, gui/gui_src_asm.cc: Right-button mouse clicks now
	bring up a menu. Currently, not all of the menu items are
	supported. Furthermore, only GtkTextTag'd text responds.

2006-04-11 Roy Rankin <rrankin@ihug.com.au>
	* src/p16f87x.cc: if code read with breadboard closed, breadboard
	  did not show processor.
	* src/pic-ioports.cc: fix portb does not show high inputs if register
	  bits cleared from assembler code.
	* regression/rt.sh: allow multiple tests in one directory
	* regression/run_regression.sh: run comparator tests seperatly
	* src/comparator.cc: cleanup compiler warnings

2006-04-08 Scott Dattalo <scott@dattalo.com>

	  src/dspic/dspic-registers.cc, src/intcon.cc, src/ioports.cc,
	  src/pic-instructions.cc:
	  removed unused variables, #if 0-ed unused functions
	  removed warnings:
	    XXXX.h: In constructor `xxxx':
	    XXXX.h:LLL: warning: `yyyy' will be initialized after
	    XXXX.h:LLL: warning:   `zzzz'
	    XXXX.cc:LLL: warning:   when initialized here

	  new files src/comparator.h src/comparator.cc
	  to add comparator and vref functions.
	* new directory regression/comparator with new files
	  compar_628.asm compar_628.stc compar_877a.asm

	  with files Makefile, 16f873.lkr, eedate_wide.asm and eeprom_wide.stc
	  for regression testing of EEPROM and FLASH single byte wide
	  read-write operations.

2006-03-30 Scott Dattalo <scott@dattalo.com>
	* gui/gui_regwin.cc: In 03-27 changes, a variable initialization
	got commented out and caused a segv on some systems

2006-03-30 Scott Dattalo <scott@dattalo.com>
	* src/14bit-registers.h, src/14bit-registers.cc: Resetting the
	program counter low register (PCL) was causing the cycle counter
	to advance by one.

2006-03-29 Scott Dattalo <scott@dattalo.com>
	* gui/gui_src_asm.cc, gui/gui_src.h:
	Source files are now only parsed whenever they're brought into
	view. (The previous commit parsed the source, but only placed it
	into a gtk_text_view whenever the source was brought into view).

	* src/processor.cc: Config addresses in the .lst file were causing
	a segv when the list file was processed.

2006-03-28 Scott Dattalo <scott@dattalo.com>
	* gui/gui_src_asm.cc, gui/gui_src.h:
	- If there are many source files, the notebook will now allow the
	tabs to be scrolled.
	- Source files are now only rendered whenever the page in which
	they reside is brought into view. (Otherwise, large projects will
	take a very long time to load).

	* gui/gui_watch.cc:
	- Watch window was causing segv for the case when a watched
	register did not have an entry in the symbol table.
	- Fixed a bug where the "hex" attribute was being repeatedly added
	to the eXdbm data base. Note this fix was only applied to
	non-WIN32 OSes
	* gui/gui_regwin.cc, gui/gui_regwin.h: The register window cells
	were not getting resized correctly whenever the font was
	changed. Also, the default font was changed to Monospace.

2006-03-24 Scott Dattalo <scott@dattalo.com>
	* src/symbol.h, src/symbol.cc: Added a convenience function for
	searching the symbol table for strings.
	* src/processor.h, src/processor.cc: Change FileContext::Add
	method to accept only a const char *.

2006-03-24 Scott Dattalo <scott@dattalo.com>
	* src/processor.h, src/processor.cc: The FileContext class now
	handles list files.
	* gui/gui_src_asm.cc, gui/gui_src.h, gui/gui_menu.cc: Breakpoints
	can be manipulated through the list file view of the source
	browser.
	Switching pages in the source browser now updates the margin.
	The preferences editor 'Margins' and 'Tabs' were combined into
	just 'Margins'.

2006-03-22 J.R. Heisey <jrheisey@sourceforge.com
	* config_win32.h.in, plat/win32/fd2raw.cpp: Removed strndup()
	for Visual Studio. Using g_strndup() from glib instead
	* src/os_dependent.cc, src/modules.h: Change parameter of
	free_error_message() from char * to const char * to go along with the change to
	get_error_message().
	* gpsim/gpsim.vcproj: Changed library from readline-static.lib to
	readline.lib in the debug build which is the correct debug library file.

2006-03-22 Scott Dattalo <scott@dattalo.com>
	* cli/input.cc, gui/gui_symbols.cc: use glib's g_strndup() instead
	of strndup.

2006-03-22 J.R. Heisey <jrheisey@sourceforge.com
	* config_win32.h.in, plat/win32/fd2raw.cpp: Created strndup()
	function for Visual Studio build.

2006-03-22 Scott Dattalo <scott@dattalo.com>
	* gui/gui_src_asm.cc:
	Last change cause segv in preferences editor.

2006-03-22 J.R. Heisey <jrheisey@sourceforge.com
	* /src/sim_context.cc: Modified forward declaration of
	get_error_message() to match recent definition change.

2006-03-22 Scott Dattalo <scott@dattalo.com>
	* src/cod.cc, src/pic-instructions.cc, src/processor.cc,
	src/processor.h:
	Fixed list file processing. Now the file context class knows if it
	owns a .lst file versus a .asm or .inc file.
	* gui/gui_src.h, gui/gui_src_asm.cc:
	List files are now displayed in the source browser. The program
	counter indicator tracks correctly. Breakpoints can not be
	controlled from within the list file view yet.
	Changed strndup calls to g_strndup. The form is a GNU extension
	while the latter is part of glib, but both do the same thing. This
	removes an OS dependency.

2006-03-21 Scott Dattalo <scott@dattalo.com>
	* gui/gui_object.cc: removed debug printf
	* gui/gui_src_asm.cc: Added a delete_event handler for the source
	browser; killing the source browser window was causing gpsim to
	crash otherwise.
	The source browser name has been updated to match the old
	browser's name (this is mainly for registry and .gpsim settings).
	Added GTK_WAIT's for slower machines. Apparently gtk's event queue
	is getting overwhelmed while the source browser is being created.

2006-03-21 Borut Razem <borut.razem@siol.net>
	* src/cod.cc: fixed bug "[ 1448454 ] usart_test - ERROR: == comparison
	  is not defined for String" by merging "assertions" and "assertions"
	  lists to a single "directive" list

2006-03-20 Scott Dattalo <scott@dattalo.com>
	* regression/breakpoints.asm: Embedded script error was causing
	regression test to fail.
	* regression/rt.sh: Minor fix to Borut's regression test
	enhancement; the 'tee' command was appending multiple regression
	tests to the same log file. Also, on Athlon 64's, the tee command
	was causing pipe errors for some reason.

2006-03-19 Scott Dattalo <scott@dattalo.com>
	* gui/gui_menu.cc, gui/gui_src.h, gui/gui_src_asm.cc:
	The preferences window now configures the source browser tabs,
	margins, and font.

2006-03-19 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.nsi: added share and lib\gtk-2.0\2.4.0\engines to
	  the package, use share\themes\MS-Windows\gtk-2.0\gtkrc as the
	  default gtkrc
	* gpsim/regression/rt.sh: failure detection

2006-03-15 Scott Dattalo <scott@dattalo.com>
	* gui/gui_src.h, gui/gui_src_asm.cc:
	Added .lst files to the source browser.
	Added the "ColorHolder" class to wrap a GdkColor that can be
	changed and reverted back to its original value.
	The colors for the source browser are now saved.
	Line numbers, addresses, and opcodes in the margin can be
	selectively enabled
	* gui/gui_menu.cc:
	Example code for src browser configuration is now rendered in a
	SourcePage.
	* gui/gui_statusbar.cc, gui/gui_main.cc, gui/gui.h,
	gui/gui_regwin.cc, gui/gui_break.cc, gui/gui_profile.cc: The
	global 'gp' has been renamed gpGuiProcessor.

2006-03-15 Alain Portal <aportal@univ-montp2.fr>
	* src/p12.h: Remove redundant class scoping (causes errors with
	gcc-4.1)

2006-03-14 Borut Razem <borut.razem@siol.net>
	* src/dspic/makefile.mingw: added
	* plat/win32/gpsim.nsi: fixed typo

2006-03-13 Scott Dattalo <scott@dattalo.com>
	* src/processor.cc: hex files were not getting loaded properly.

2006-03-12 Scott Dattalo <scott@dattalo.com>
	* src/pic-ioports.cc: PIC TRIS writes were not getting traced.

2006-03-12 Borut Razem <borut.razem@siol.net>
	* config_win32.h.in: added #define _USE_MATH_DEFINES, so that M_PI
	  is defined in MSVC math.h

2006-03-12 Scott Dattalo <scott@dattalo.com>
	* gui/gui_src.h, gui/gui_src_asm.cc, gui/gui_menu.cc:
	- Gui Preferences for source browser is *almost* working now. It's
	possible to modify colors, but the state of the colors are not
	being saved in the gpsim config file. Also, the line number,
	address, opcode configuration is not completed.
	- The Source browser now utilized the text_view margin for
	displaying addresses and opcodes. Also, breakpoints changes the
	margin field text to red. (This duplicated the diamond indicator,
	but I plan to use that for modifying complex breakpoints).

2006-03-12 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.nsi, doc/gpsimWin32.html, plat/win32/make.mingw,
	  cli/makefile.mingw, gpsim/makefile.mingw, gui/makefile.mingw,
	  modules/makefile.mingw: glib-2.8.6, gtk+-2.8.13, pango-1.10.2,
	  atk-1.10.3, cairo-1.0.2, ...

2006-03-09 Borut Razem <borut.razem@siol.net>
	* examples/modules/usart_gui/usart_gui.asm,
	  examples/modules/usart_gui/usart_gui.stc:
	  Renamed the usart RX and TX pins to RXPIN and TXPIN

2006-03-07 Scott Dattalo <scott@dattalo.com>
	* src/gui_src_asm.cc: Turned off debugging. Added a gtk event
	queue wait.
	* src/gui_processor.h: The default is to now enable the new source
	browser.

2006-03-06 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.cc: The stimulus command without any options now
	shows more information. In particular, value stimuli (the ones
	that allow you to specify an array of data) are now shown.

2006-03-06 Scott Dattalo <scott@dattalo.com>
	* doc/gpsim.lyx, doc/gpsim.pdf: Updated the documentation to
	reflect the deprecation of the X command

2006-03-06 Scott Dattalo <scott@dattalo.com>
	* gui/gui_menu.cc, gui/gui_src.h, gui/gui_src_asm.cc: Moved the
	gtk text tag table to the source browser parent class. Added a
	SourceBuffer class to wrap the text buffers. With these changes,
	multiple source browsers will share the same text buffers.

2006-03-06 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_x.cc: The x command has been deprecated.

2006-03-05 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.h: The default Thevenin resistance for an IOPIN was
	too low. This caused an INPUT only pin to appear as though if it
	was driving! (Bug reported by Alex Holden).

2006-03-05 Borut Razem <borut.razem@siol.net>
	* configure.ac: removed GTK+ 1.x leftovers
	* plat/win32/gpsim.nsi: remove extras/graphic_lcd/* when uninstalling
	  gpsim, added extras/usart_con
	* extras/usart_con/AUTHORS, extras/usart_con/autogen.sh,
	  extras/usart_con/ChangeLog, extras/usart_con/configure.in,
	  extras/usart_con/COPYING, extras/usart_con/INSTALL,

	  extras/usart_con/README, extras/usart_con/usart_con.cc,
	  extras/usart_con/usart_con.h: receive-only usart module,
	  received characters are printed to the console

2006-03-04 Scott Dattalo <scott@dattalo.com>
	* gui/gui_menu.cc, gui/gui_src.h, gui/gui_src.cc: See comment on
	2006-02-27. Removed the line numbers from the source
	browser. Changed the current PC and breakpoint indicator. Also,
	now clicking on a break indicator toggles a break point.

2006-03-04 Scott Dattalo <scott@dattalo.com>
	* src/modules.h, src/modules.cc, src/os_dependent.cc: Changed
	references from char * to const char * for error strings
	processing. (Alex Holden reports that on BSD dlerror returns const
	char * where as on linux it returns plain char *).

2006-03-04 Scott Dattalo <scott@dattalo.com>
	* cli/ui_gpsim.cc: GlobalVerbosityAccessor verbose was declared
	twice! (Thanks to Alex Holden for pointing this out).

2006-02-27 Scott Dattalo <scott@dattalo.com>
	* src/processor.cc: FileContext put_address and get_address
	methods were ignoring the last line of files.
	* gui/gui_src.h: Rewrote the source browser using the gtk+-2.X
	API.
	*** NOTE *** The older version of the source browser is still
	present and enabled by default. To enable the new browser,
	'NEW_SOURCE_BROWSER' needs to be defined. (This can either be
	accomplished by ./configure or by editing gui/gui_processor.h
	* gui/gui.h, gui/gui_processor.h: Added new source window class to
	list of gui classes.
	* gui/gui_menu.cc: ifdef'd removed the source browser preference
	configuration (for now)
	* gui/gui_object.cc, gui/gui_object.h: set_name() now requires const
	char * instead of just char *.

2006-02-25 Borut Razem <borut.razem@siol.net>
	* src/p18x.cc: EEPROM sfr registers were not mapped on 16 bit pics

2006-02-20 Borut Razem <borut.razem@siol.net>
	* src/os_dependent.cc: reverted changes I made 2006-02-19,
	  since the GPSIMPATH functionality was already implemented

2006-02-20 Scott Dattalo <scott@dattalo.com>
	* src/symbol.cc: Symbol_Table::clear() crashes when the simulation
	engine is used as a stand alone library (Reported by David Saxtion).

2006-02-19 Borut Razem <borut.razem@siol.net>
	* regression/switch_test/switch_test.stc,
	  examples/modules/usart_gui/usart_gui.stc: removed .so extension
	  from "module library libgpsim_modules.so" so that it runs on WIN32
	  platform
	* src/modules.cc: made ModuleLibrary::MakeCanonicalName() a dummy
	  method on WIN32 platform. Is it really needed on *nix?
	* src/os_dependent.cc: introduced GPSIM_MODULE_PATH environment
	  variable on WIN32 platform  to define additional directories where
	  modules are searched. The search order for WIN32 is as follows:
	    1. The directory specified by library_name.
	    2. The current directory.
	    3. The system directory.
	    4. The 16-bit system directory.
	    5. The Windows directory.
	    6. The directory from which the application loaded
	      followed by directories listed in GPSIM_MODULE_PATH environment
	      variable followed by directories listed in PATH environment
	      variable.

2006-02-17 Scott Dattalo <scott@dattalo.com>
	* src/16bit-instructions.cc, src/16bit-instructions.h,
	src/16bit-hexdecode.cc: Fixed a few bugs with the newly added
	extended instructions.
	* src/16bit-processors.cc, src/16bit-processors.cc,
	src/16bit-registers.cc:
	added the pclatu register.
	* src/pic-instructions.cc: the instruction class constructor now
	initializes most of it's data members directly.

	* regression/make.regression: .cod files are now removed for the
	'make clean rule'
	* regression/run_regression.sh,
	regression/p18f/18f452.lkr, p18f/Makefile,
	p18f/extended_instructions.asm, p18f/instructions.asm,
	p18f/startup.stc:
	Regression test for the 18f extended instructions.

2006-02-16 Borut Razem <borut.razem@siol.net>
	* plat/win32/libgpsim.def: MSVC sync

2006-02-14 Scott Dattalo <scott@dattalo.com>
	* src/16bit-instructions.cc, src/16bit-instructions.h,
	src/16bit-hexdecode.cc: Added support for the extended
	instructions ADDFSR, ADDULNK, CALLW, MOVSF, MOVSS, SUBFSR, and
	SUBULNK, in the 18fxxxx family.

2006-02-13 Scott Dattalo <scott@dattalo.com>
	* src/gui/gui_menu.cc: more source browser experiments.

2006-02-08 Scott Dattalo <scott@dattalo.com>
	* modules/usart.cc:
	Renamed the usart RX and TX pins to RXPIN and TXPIN. The old names
	conflict with the names of constants. (This is a problem with
	absolute mode code.)
	Updated the gui to use gtk_text_view instead of the obsolete
	gtk_text. (note this change really needs to be made for all of
	gpsim's gui!)

2006-02-08 Scott Dattalo <scott@dattalo.com>
	* src/dspic/dspic-instructions.cc, src/dspic/dspic-instructions.h:
	Support for some versions of the MOV instruction.

2006-02-05 Scott Dattalo <scott@dattalo.com>
	* src/dspic/dspic-instructions.cc, src/dspic/dspic-instructions.h,
	src/dspic/dspic-processors.cc, src/dspic/dspic-processors.h,
	src/dspic/dspic-registers.cc, src/dspic/dspic-registers.h:
	Unified the Literal and Register Direct addressing modes.
	Added support for the Status register.
	Program counter tracing is now supported.

2006-02-04 Scott Dattalo <scott@dattalo.com>
	* src/dspic/dspic-instructions.cc, src/dspic/dspic-instructions.h,
	src/dspic/dspic-processors.cc:
	Added support for the Literal, Register Direct,  and Register
	Indirect addressing modes.

2006-02-03 Roy Rankin <rrankin@ihug.com.au>
	* src/processor.cc, src/pic-processor:
	The pic-processor class was over-writing the
	cycles_per_instruction value in the processor class
	* modules/switch.cc, modules/switch.h, modules/resistor.cc,
	regression/switch_test/switch_test.stc,
	regression/switch_test/switch_test.asm:
	Switch modules now handle analog inputs and RC loads.

2006-01-30 J.R. Heisey <jrheisey@sourceforge.com
	* Changed the implementation of Float::copy() to use the get()
	function to retrieve the value.

2006-01-30 Scott Dattalo <scott@dattalo.com>
	* src/processor.cc, src/processor.h: added methods for mapping
	register addresses into register indexes (for the dspic) and use
	this to create invalid registers.
	* src/registers.cc: contructors now propagate calls to parents
	* gui/gui_regwin.cc: a non-existent register at address 0 was
	crashing the register window
	* src/dspic/dspic-instructions.cc, src/dspic/dspic-instructions.h,
	src/dspic/dspic-processors.cc, src/dspic/dspic-processors.h,
	src/dspic/dspic-registers.cc, src/dspic/dspic-registers.h:
	dspic port:
	  -- added register memory
	  -- added W0-W15
	  -- invalid registers populate register space
	  -- added Program Counter
	  -- single stepping works.
	  -- GOTO, RCALL and BRA instructions are now supported.

2006-01-25 Roy Rankin <rrankin@ihug.com.au>
	* gui/gui_profile.cc: fix core dump

2006-01-29 J.R. Heisey <jrheisey@sourceforge.com
	* cli/cmd_break.cc: I prevent ei from being incremented for
	pThird if pSecond does not exist. This was causing a crash
	in Windows because pThird ended up point to the same object
	as pFirst. (go figure) Later pThird was getting deleted then
	pFirst (the same object) was getting referenced causing the
	crash.
	(i.e. break e MYLABEL where MYLABEL is not defined.) I also
	added a check to bpn == -1 and write an error. This provides
	an error message if a code symbol is not defined.

2006-01-28 Borut Razem <borut.razem@siol.net>
	* makefile.mingw, src/makefile.mingw, gpsim/makefile.mingw,
	  plat/win32/make.mingw: added dspic to MINGW

2006-01-27 Scott Dattalo <scott@dattalo.com>
	* src/dspic/dspic-registers.cc, src/dspic/dspic-registers.cc:
	added to CVS - initial support of dspic family registers
	* src/dspic/Makefile.am: dspic-registers added
	* src/dspic/dspic-instructions.cc, src/dspic/dspic-instructions.h:
	stubbed out the entire dspic instruction set.
	* src/dspic/dspic-processors.cc, src/dspic/dspic-processors.h:
	added initialization code to allow the dspic to be instantiated.
	* src/hexutils.cc: fixed two buglets introduced in earlier checkin
	* src/pic-instructions.cc: the invalid_instruction constructor now
	calls the Instruction constructor.
	* src/processor.cc: The disassemble method can now accommodate the
	dspic's 24-bit opcodes.

2006-01-27 Scott Dattalo <scott@dattalo.com>
	* configure.ac: changed version from 0.21.11 to 0.21.12-pre
	* cli/scan.ll: conditionally use YY_* macros.

2006-01-27 Scott Dattalo <scott@dattalo.com>
	* Makefile.am, configure.ac, src/Makefile.am: update makefiles for
	dspic support.

	src/dspic/dspic-instructions.h, src/dspic/gpsim_modules.cc,
	src/dspic/dspic-processors.cc, src/dspic/dspic-processors.h:
	Initial infrastructure for dspic port.
	* src/hexutils.h: New file.
	* src/hexutils.cc, src/program_files.cc: Hex files generated by
	gpasm and mpasm are really Intel hex files. The hex files
	generated by the gcc-pic30 tool chain also generate Intel hex
	files. Now gpsim supports more of the features of the Intel hex
	file format.
	* src/pic-processor.cc, src/pic-processor.h, src/processor.cc,
	src/processor.h: minor changes to deal with Hexfiles.
	* src/p16x6x.cc: TMR1L and TMR1H were named as just tmrl and tmrh

2006-01-21 Borut Razem <borut.razem@siol.net>
	* src/stimuli.cc: fixed bug exposed by resistor regression test,
	  see the comment "; the following test for a core dump bug" in
	  regression/resistor/resistor.asm
	* cli/cmd_module.cc: added missing paramterer to DisplayMessage() call

2006-01-20 Borut Razem <borut.razem@siol.net>
	* plat/win32/libgpsim.def: MSVC sync

2006-01-20 Scott Dattalo <scott@dattalo.com>
	* src/trigger.cc, src/breakpoints.cc: Breakpoint messages were not
	getting printed when execution breakpoints were hit.

2006-01-19 Scott Dattalo <scott@dattalo.com>
	* cli/parse.yy, cli/cmd_break.cc, cli/cmd_break.h, src/breakpoints.cc
	Rewrote breakpoint parsing. gpsim recently introduced an
	expression option for breakpoints. As this feature was refined, it
	turned out that the best way to handle expressions was with a two
	level approach. At the high level, there is a 'break condition',
	e.g. 'break w MyVariable'. The condition in this case is to break
	if the variable 'MyVariable' is written to. At the next level,
	there is a qualifying expression. For example:
	   break w MyVariable, ((PC > IntVector) && (PC<IntVectorEnd))
	In other words, this break occurs if the interrupt routine is
	executing when ever 'MyVariable' is written to.
	 One of the refinements was to turn the 'break condition' into an
	expression. Eg. 'break w ((MyVar &0xf)==4)'. Here, the condition
	is an expression. This condition can have an additional qualifying
	expression.
	     *** Command Line Syntax Change ***
	The old syntax is:
	    break type condition [expression] [,"message"]
	The new syntax is:
	    break type condition [,expression] [,"message"]

	The difference is that the new syntax requires a comma between the
	condition and the qualifying expression.

	* cli/input.cc: embedded scripts were not executing in proper
	order.

	* regression/breakpoints/breakpoints.asm,
	regression/digital_stim/digital_stim.asm,
	regression/instructions_12bit/instructions_12bit.asm,

	* src/cod.cc: Insert commas between breakpoint expressions.

	* src/operator.cc, src/operator.h: Comparison expressions now
	support breakpoints

	* eXdbm/misc.c: Deleting a non-existent item from the data base
	was causing a crash.

2006-01-12 Scott Dattalo <scott@dattalo.com>
	* src/errors.h, src/sim_context.cc: Slight clean up to Roy's
	patch.

2006-01-12 Roy Rankin <rrankin@ihug.com.au>
	* src/modules.cc: remove library load failure exception throw. In
	Linux, a failed module library load command from the command
	window repeats the error message already printed.  Even worse, if
	the failure occurs fromthe breadboard GUI "Add libs" function,
	gpsim crashes.

	* src/os_dependent.cc: Fix up error handling on library loads for
	Linux. Also for readability changed #ifndef _WIN32 to #ifdef
	_WIN32 reversing the cases.


2006-01-10 J.R. Heisey <jrheisey@users.sourceforge.com
	* gui\gui_watch.cc gui\gui_watch.h, gui\gui.h, gui\gui_object.cc,
	gui\settings.h, gui\settings_exdbm.cc, gui\settings_exdbm.h,
	plat\win32\settings_reg.cpp, plat\win32\settings_reg.h:
	Fixed bug where loading a hex file a second time in the same
	gpsim sesssion caused the watch window to be populated with
	multiple instances of the same previously entered symbols.
	Created a config_remove() function to remove entries from
	the Settings database.
	* src\sim_context.cc, src\sim_context.h, src\symbol.cc,
	cli\input.cc: Changed catch_control_c() function to call
	CSimulationContext::NotifyUserCanceled() rather than
	Breakpoints:halt(). NotifyUserCanceled() now calls halt() and other
	processing depending the context.
	Added code to allow a user to abort the symbol listing to the
	console by pressing CTRL-C.
	* gui\gui_regwin.cc: Fixed some crashing bugs that occured when
	you click on a watch window row when the register window has
	not been built.

2006-01-06 Roy Rankin <rrankin@ihug.com.au>
	* modules/led.cc, modules/led.h: Added dynamic gui update to the
	led modules.

2006-01-07 Scott Dattalo <scott@dattalo.com>
	* regression/resistor/resistor.asm: Tiny comment change
	* regression/run_regression.ch: Added the resistor regression test
	to the test suite.

2006-01-07 Roy Rankin <rrankin@ihug.com.au>
	* modules/resistor.cc: Pulldown resistor voltage is now set to 0
	Volts.
	* src/stimulus.h, src/stimuli.cc: Adjusted default resistance
	values for stimuli to more closely match PIC I/O pins.
	* regression/resistor/resistor.asm: Set pulldown resistance for
	the pulldown resistor.

2006-01-06 Roy Rankin <rrankin@ihug.com.au>
	* src/stimuli.cc: Fixed crash regarding module pin names.
	* regression/resistor/Makefile: New regression test for the
	resistor module.
	* regression/resistor/resistor.asm:
	* regression/resistor/resistor.stc:
	* regression/resistor/16f873.lkr:


2006-01-02 Scott Dattalo <scott@dattalo.com>
	* src/ui.h, src/ui.cc: added another method for formatting
	registers (though this might be removed later).
	* src/value.h, src/value.cc: Moved Value specific breakpoint
	functionality to the Value class. Fixed typo in an error message.
	* src/symbol.cc, src/symbol.h: Fixed a bug with clearing the symbol table.
	 - Added breakpoint expression compilation to the register_symbol
	 class (this was previously being handled in cli/cmd_break.cc).
	 - The w_symbol now is printed out as a W register.
	* src/module.h, src/processor.h: moved the register_size and
	register_mask methods from the processor class to the module
	class. (Modules can have regsiters too!).
	* src/p16x7x.cc, src/p16x6x.cc, src/p16x5x.cc, src/p16f87x.cc,
	src/p16f62x.cc, src/16bit-processors.cc, src/14bit-processors.cc:
	W was not getting added to the symbol table.
	* src/gpsim_time.cc: stopwatch changes to conform to value class api.
	* src/breakpoints.cc, src/breakpoints.h: cleaned up/fixed printout of
	register breakpoints. Added a more generic 'set_break()' method
	that replaces several other specific methods (the old ones haven't
	been removed yet).
	* cli/parse.yy: certain read and write break points were not
	getting parsed properly.
	* cli/scan.ll: echo command was failing to be recognized.
	* cli/cmd_break.cc: moved most of the expression parsing into the
	simulation engine.
	* src/expr.h, src/expr.cc: LiteralSymbols are cast into either
	registers or program memory address when breaks are set on them.
	* src/cod.cc: pruned some dead code.
	* src/tmr0.cc, src/tmr0.h: TMR0 class now conforms to new break API.

2006-01-02 Scott Dattalo <scott@dattalo.com>
	* configure.ac, cli/input.cc, cli/socket.cc: add configuration
	option to inhibit the socket interface.

2005-12-31 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.nsi: added examples/modules/usart_gui/*.* and
	  extras/graphic_lcd/*.* to the WIN32 setup

2005-12-30 Scott Dattalo <scott@dattalo.com>
	* src/value.cc, src/value.h: Clarified error message when user
	attempts to set or clear breakpoints on register symboles. Also,
	fixed error message on Integer casts to Booleans.
	* src/bitlog.h, src/bitlog.cc: Added dump() and dump_ASCII_art()
	methods to the ThreeStateEventLogger class. These are debug
	functions used to examine event logs.
	* modules/usart.cc: Utilize new event logger utilities.


2005-12-28 Scott Dattalo <scott@dattalo.com>
	* regression/breakpoints, regression/breakpoints/breakpoints.asm,
	regression/breakpoints/Makefile,
	regression/breakpoints/16f873.lkr,
	regression/breakpoints/breakpoints.stc: Added a regression test
	for testing breakpoints. (Not much there yet)

2005-12-28 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_break.cc, src/breakpoints.cc: gpsim would crash if a
	break point was set on a register that did not have a symbol table
	entry.

2005-12-28 Roy Rankin <rrankin@ihug.com.au>
	* modules/usart.cc, modules/usart.h: Fixed bugs in
	mSendByte. Fixed usart attributes. Cleaned up error messages.
	* modules/usart.cc, modules/usart.h: Added a gui interface to the
	usart module.
	* examples/modules/usart_gui/Makefile: New
	* examples/modules/usart_gui/README: New
	* examples/modules/usart_gui/usart_gui.asm: New
	* examples/modules/usart_gui/usart_gui.stc: New. The usart_gui
	example illustrates the new Usart GUI interface.

2005-12-23 J.R. Heisey <jrheisey@sourceforge.com
	* src/breakpoints.cc, src/cmd_gpsim.h, cli/cmd_module.cc,
	cli/cmd_processor.cc, gpsim/gpsim.vcproj, gui/gui_breadboard.cc,
	src/interface.cc, plat/win32/libgpsim.def, src/Makefile.am,

	src/sim_context.h, src/src.vcproj, src/symbol.cc, src/symbol.h,
	cli/ui_gpsim.cc, src/ui.cc, src/ui.h: Refactored the functions
	in module.cxx into a ModuleLibary class that contains various
	lists in preparation for a gpsim Perl API. Also fixed the
	gui_breadboard iteration of modules. Now they display
	properly.

2005-12-23 Scott Dattalo <scott@dattalo.com>
	* src/symbol.cc: findRegisterSymbol dumped core if a register was
	being loaded from a module (and not from a processor)
	* src/os_dependent.cc, src/processor.cc: Relative paths were
	getting concatenated to absolute paths
	* src/16bit-processors.cc: ccp1 is now associated with portc2

2005-12-19 Scott Dattalo <scott@dattalo.com>
	* src/icd.cc, src/modules.cc, src/pic-processor.cc,
	src/sim_context.cc, modules/paraface.cc: Re-added needed unistd.h
	includes that were removed on 2005-12-10. New systems may not
	unistd, but older ones do.

2005-12-17 Scott Dattalo <scott@dattalo.com>
	* cli/input.cc: removed glib dependencies for non-gui builds

2005-12-16 Scott Dattalo <scott@dattalo.com>
	* src/ioports.h, src/ioports.cc, src/pic-ioports.h,
	src/pic-ioports.cc: moved some of the functionality in the
	PicPort classes upto the generic Port classes. Also added
	comments.

2005-12-12 J.R. Heisey <jrheisey@sourceforge.com
	* cli\cmd_symbol.cc, cli\cmd_symbol.h, src\operator.cc,
	cli\parse.yy: I've reconsidered regarding implementing
	and indirection operator. The ampersand character may
	now be used to reference a integer value or a register
	symbol as an indirection operator. I've also made
	it possible to type only an expression enclosed in parens.
	The expression will evaluate and be printed on the next
	console.

2005-12-11 J.R. Heisey <jrheisey@sourceforge.com
	* src\expr.cc, src\expr.h, src\operator.cc, src\operator.h,
	cli\parse.yy, cli\scan.ll, src\symbol.cc, src\symbol.h,
	src\value.cc src\value.h: Problems with expression evaluation.
	Could not evaluate A=-X. Added evaluate() function to class
	Value and a pecialized implementations to relevant derived
	classes. The LiteralSymbol::evaluate() now calls the symbols
	evaluate() so that a register_symbol will return the register
	contents.
	* Also implemented reg(int) as an expression so it can be
	included in calculations
	* Implemented the ampersand character as an 'address of' operator
	Fixed minus sign for negation and one's complement.
	* src/gpsim_object.cc: gpsimObject:showType() now does not
	include the word class for the type for Windows.

2005-12-11 Borut Razem <borut.razem@siol.net>

	* src/16bit-instructions.h, src/breakpoints.h, src/pic-instructions.h,
	  src/pic-instructions.cc, src/processor.h, src/processor.cc:
	  fixed gcc errors: processor.h:150: error: using typedef-name
	  `instruction::INSTRUCTION_TYPES' after `enum'

2005-12-10 J.R. Heisey <jrheisey@sourceforge.com>src/registers.h:
	* src/expr.cc, src/ValueCollections.cc, src/ValueCollections.h:
	Added toString(ExprList_t*) and move some code from
	IndexedSymbol::toString() into it.
	* src/modules.cc, src/modules.h: Added functions for deleting
	module libraries.
	* 14bit-processors.cc, src/14bit-processors.h, src/p12x.h,
	src/16bit-processors.h, src/p16f62x.cc, src/p16x5x.cc,

	src/src.vcproj, src/ioports.cc, src/ioports.h, src/pic-ioports.cc,
	src/pic-ioports.h: Moved PicPortBRegister, PicTrisRegister and
	PicPortRegister definitions into these files from ioports.cc
	and ioports.h. Added pic-ioports.cc,h to build files. This was
	motivated by moving undesirable code for the SWIG script
	language builds.
	* src/value.cc, src/value.h: Renamed New() to NewObject() to
	avoid conflict with SWIG.
	* src/breakpoints.h, src/interface.h, src/os_dependent.cc,
	src/pic-instructions.h, src/pic-processor.cc, src/pic-processor.h,
	src/processor.cc, src/processor.h, src/stimuli.h, src/trace.h:
	removed unneeded reference to the header unistd.h.

2005-12-06 Scott Dattalo <scott@dattalo.com>

	* src/ioports.h, src/ioports.cc: Cleaned up the IOPORT class and
	deprecated some old functions.
	* src/stimuli.cc: use new IOPORT class functions.
	* modules/encoder.cc, modules/logic.h, modules/paraface.cc,
	modules/push_button.cc: Updated to new I/O port class api.
	* gui/gui_src_asm.cc: Removed printf debug

2005-12-05 Scott Dattalo <scott@dattalo.com>

	* gui/gui_src_asm.cc: Source browser crashed if there was no
	instruction at the current PC.

	* regression/instructions_16bit/18f452.lkr: mchip stock linker
	script has a bug with hard coded interrupt routine size.

2005-12-04 Robert Pearce <rob@bdt-home.demon.co.uk>

	* src/p12.cc, src/p12.h: Added pullups to 12bit-core I/O pins

2005-12-03 Robert Pearce <rob@bdt-home.demon.co.uk>

	* src/p12.cc, src/p12.h, src/pic-processors.cc,
	src/pic-processors.h: Added the 10F202.

2005-12-02 Scott Dattalo <scott@dattalo.com>
	* eeprom.cc, eeprom.h, i2c-ee.cc, i2c-ee.h, registers.cc,
	registers.h, processors.cc:
	Extended the RegisterCollection class to support an arbitrary
	array of Registers. Added CLI access to the EEPROM.
	Usage:
	   eeData
	shows all eeprom registers.
	   eeData[expression]
	shows one or several eeprom registers.
	* packages.cc, packages.h: Added better support for module pin
	placement.
	* gui/gui.h, gui/gui_breadboard.cc, gui/gui_breadboard.h,
	gui/gui_main.cc: Cleaned up package creation in preparation for
	a graphic LCD module.

	  gpsim/makefile.mingw, gui/makefile.mingw, modules/makefile.mingw,
	  src/makefile.mingw, regression/README: MINGW sync

2005-11-22 J.R. Heisey <jrheisey@sourceforge.com>
	* cli\cmd_log.cc gui\gui_regwin.cc src\init.cc src\pic-processor.cc,
	src\trace.cc src\trace.h: Changed references of trace_log to
	GetTraceLog() to decouple the global trace_log in the libgpsim.so/dll
	from the executable. Please do the same with any other globals
	you find and that I missed.

	src\expr.cc: Implemented dumping a range of an indexed variable
	using the integer range operator. (i.e. ramData[3:20]

2005-11-21 J.R. Heisey <jrheisey@sourceforge.com>
	* src\symbol.cc src\symbol.h src\ValueCollections.cc
	src\ValueCollections.h: Fixed couple bugs and added additional
	support for ndexable variables.
	* src\value.cc src\value.h: Fixed bitmask issue with the copy
	constructor of Integer. Added assignment operator to Integer
	from const Integer&.
	* src\ValueCollections.cc src\ValueCollections.h again:
	Implemented the omitted ability to do array=value and
	array[range]=value.

2005-11-21 J.R. Heisey <jrheisey@sourceforge.com>

	src\ttoken.cc, src\ttoken.h, cli\ui_gpsim.cc, cli\cli.vcproj,
	gui\gui.vcproj, src\src.vcproj, gpsim\gpsim.vcproj:
	These changes are for building the files in the src folder
	as the library libgpsim.dll under Windows. There were a couple
	of global variables that needed to be decoupled with accessor
	functions for access from gpsim.exe and other modules.
	I found that putting global variables in the gpsim.def file
	didn't work. The globals needing accessor functions were realtime_mode,
	reatime_mode_with_gui, verbose, and use_icd.
	I also needed to create the NullConsole and NullUserInterface class
	in src. These provide IConsole and IUserInterface objects
	with no implementation. Now cli in gpsim.exe creates it own
	implementation and passes it to the function SetUserInterface().
	Any other application that links to libgpsim.dll and expects test
	messages will need to pass there own IConsole and IUserInterface
	implementations. At some point I hope I (or someone) will clean
	up all of the cout references and use the GetUserInterface() function.
	Renamed macros in exports.h from GPSIM_DLL_EXPORT, GPSIM_EXT_CLASS,
	and GPSIM_EXPORT to added the LIB prefix reflecting the new
	library file.
	Created a new file libgpsim.def and moved all the symbols from
	gpsim.def into it. Emptied gpsim.def of all symbols.
	References to bp now call get_bp().
	References to ui now call

2005-11-13 Scott Dattalo <scott@dattalo.com>
	* gui/gui_menu.cc: The experimental Preferences window caused a
	crash if it was opened, but the source browser was not opened.

2005-11-13 Borut Razem <borut.razem@siol.net>

	* plat/win32/gpsim.def: MSVC sync
	* modules/switch.cc: added #include <assert.h>

2005-11-12 Scott Dattalo <scott@dattalo.com>

	* cli/input.cc, cli/scan.ll: Under certain conditions, command
	assertions were causing the lexer to get confused.
	* gui/gui_menu.cc: experiment code with preferences.
	* src/ioports.cc, modules/encoder.cc, modules/paraface.cc,
	modules/push_button.cc: Calls to Stimulus_Node->update() method
	unnecessarily passed the current simulation time.
	* modules/resistor.cc, modules/resistor.h: The pullup resistor
	module was completely broken.
	* modules/switch.cc, modules/switch.h: The switch module never did
	work, but now it does! This is now truly a two-port device.
	* src/gpsim_time.cc, src/gpsim_time.h: Added methods to control
	the real time to simulated time mapping.
	* src/breakpoints.cc: Command Assertions were unnecessarily adding
	an extra '\n' to the end of the command string.
	* src/stimuli.cc, src/stimuli.h: Originally node updates would
	update the node state and refresh connected stimuli all within the
	context of a single method. Now this has been split into two
	methods. This was added to support the switch module. In addition,
	the new method 'getThevenin()' retrieves the full electrical state
	of a stimulus.

2005-11-09 Robert Pearce <rob@bdt-home.demon.co.uk>

	* src/pic-processor.cc, src/processor.cc: Update simulation time
	base when ever the processor's oscillator frequency is changed.

2005-11-08 Borut Razem <borut.razem@siol.net>

	* makefile.mingw: MINGW sync

2005-11-06 J.R. Heisey <jrheisey@sourceforge.com>
	* src/cmd_gpsim.h: Ability to format a value using a bit mask.
	* cli/cmd_symbol.h: Routines to dump and set an indexed
	value.
	* cli/cmd_x.cc cli/cmd_x.h: Lets use set reg(2)=expr.
	* src/processor.h: Implemented new function Processor::
	ConstructInvalidInstruction() function to allow derived classes
	to define there own Invalid instruction types.
	* src/expr.cc src/expr.h, src/ValueCollections.cc,h, src/symbol.cc
	src/symbol.h: Implemented classes to expose to the command prompt
	interface an indexed variable symbol type commonly refered to as
	arrays.
	* cli/scan.ll, cli/parse.yy: Implemented the parsing of indexed
	(array) variables in the command language.
	RAM, EEPROM and ROM are the first ones.
	(i.e. RAM[$20])
	* cli/scan.ll: Implemented strings as single quotes as well as
	double quotes.
	* Fixed issue where setting a RAM value from the command
	prompt would not update the GUI windows.
	* cli/parse.yy: Allow setting a RAM using the reg() operator.
	(i.e. reg(3)=54)
	* src/value.cc src/value.h: Added extra operators for Integer and
	Float. Also added a bitmask for Integer to be used for display
	purposes.
	* src/registers.cc,h: Implemented RegisterCollection class.
	* src/sim_context.cc: In CSimulationContext::Clear() now clear
	the symbol table after I delete the processors in the processor
	list. This provents the symbol table from deleting a symbol
	that is actually owned by the processor.

2005-11-02 Robert Pearce <rob@bdt-home.demon.co.uk>
	* src/tmr0.cc, src/stimuli.cc: Fix TMR0 external clocking
	ploarity. Fixed a typo in IOPIN::getBitChar().

2005-10-24 Scott Dattalo <scott@dattalo.com>
	* src/gpsim_time.cc, src/gpsim_time.h: Fixed a nasty cycle counter
	bug that would erroneously clear a break point whenever two breaks
	were set at the same cycle.
	* src/interface.cc: Interface callback breakpoint now can display
	a message in the breakpoint list.
	* src/p16x6x.cc, src/p18x.cc, src/pir.cc, src/pir.h,
	src/14bit-tmrs.cc, src/14bit-tmrs.h, src/16bit-processors.cc: The
	whole "pir_set" design needs to be re-implemented. At issue is
	that every pic potentially has a different bit mapping for the PIR
	registers. The pir_set desgin attempts to accommodate this with
	pure VF's. Unfortunately, peripherals like the TMRL class that
	need to set PIR bits only can call specific methods like
	"set_tmr1f()". However, the TMRL class is used as a base for TMR3
	too! I created a new class called "InterruptSource" that can
	trigger interrupts instead.

2005-10-21 Borut Razem <borut.razem@siol.net>
	* makefile.mingw, plat/win32/makefile.mingw, plat/win32/make.mingw,
	  plat/win32/gpsim.nsi: building gpsim setup executable on WIN32

2005-10-20 Scott Dattalo <scott@dattalo.com>
	* regression/make.regression: modified the default make target
	to create a .cod file
	* regression/tmr0_16bit/Makefile,
	regression/tmr0_16bit/tmr0_16bit.asm: Added tests for 16bit mode
	of tmr0.
	* regression/tmr0_16bit/delay.inc,
	regression/tmr0_16bit/delay.asm: Added to CVS. Made the delay routine a separate
	source module. Also, a DELAY macro has been created so that
	exactly N cycles can be delayed, where  0 < N < 65536+15.
	* src/16bit-processors.cc: portd and porte registers were not
	getting added to the symbol table.

	* src/pic-instructions.cc, src/pic-instructions.h: Added methods
	to the instruction class that provide acces to the source defining
	an instruction (this is going to be used with tracing and
	disassembly soon).

	the command assertion will issue a gpsim command line command.
	* gpsim/main.cc: removed a debug printf.
	* cli/input.cc, cmd_macro.cc, cli/ui_gpsim.cc: command assertions
	were getting inserted into the end of the command line input

	* gui/gui_menu.cc: More source browser preference configuration.
	* gui/gui_regwin.cc: Turned register sheet rows and columns back
	on. (They were off because of a bug in gtkextra, but that bug is
	fixed now).
	* src/16bit-processors.cc, src/16bit-registers.cc, src/p18x.cc,
	src/tmr0.cc:
	The create+sfr_map() method was getting called twice fof the p18f
	devices.
	T0CON was not retaining its 0xff reset value.
	TMR0L was reporting the wrong value while it was turned off.
	* regression/run_regression.sh, regression/tmr0_16bit/18f452.lkr,
	regression/tmr0_16bit/Makefile,
	regression/tmr0_16bit/tmr0_16bit.asm,

2005-10-01 Scott Dattalo <scott@dattalo.com>
	* src/processor.cc: Changed Processor::init_program_memory_at_index()
	so a derived processor can define its own bad_instruction type.

	Fixed a crashing bug in trim() when a empty was passed in.

2005-09-30 Scott Dattalo <scott@dattalo.com>
	* gui/gui_menu.cc, gui/gui_src.h, gui/gui_src_asm.cc: Source
	browser clean up.

2005-09-29 Scott Dattalo <scott@dattalo.com>
	* gui/gui_menu.cc, gui/gui_src.h, gui/gui_src_asm.cc: More
	preferences work; now the colors for the source browser example
	text can be configured (this configuration doesn't map back into
	the source browser yet).

2005-09-28 Scott Dattalo <scott@dattalo.com>
	* src/16bit-registers.cc, src/16bit-registers.h, src/tmr0.cc,
	src/tmr0.h: The high byte of TMR0 for the 18F family was not
	updating correctly in certain circumstances (like during single
	stepping). Thanks to Robert Merkel <robert.merkel@benambra.org>
	for reporting this issue.

	multi-line symbol values.

2005-09-21 J.R. Heisey <jrheisey@sourceforge.com>
	* src/cod.cc: Added an extra test to prevent a error message
	from displaying when a non cod file attempted. This really
	should validate that the file is a cod file earlier.

2005-09-20 Scott Dattalo <scott@dattalo.com>
	* gui/gui_regwin.cc: GUIRegisterList.register_size was being set
	improperly.

	* gui/gui_src.h, gui/gui_src_asm.cc, src/breakpoints.cc,
	src/breakpoints.h, src/pic-instructions.cc,
	src/pic-instructions.h, src/processor.cc, src/trace.cc:
	Fixed usability issues with setting breakpoints through the source
	browser. The 'Drag Break' feature has been disabled since it
	really doesn't work too well for assertions (or at least doesn't
	apply). Fixed a bug that prevented toggling breaks that occur at
	the current PC.
	A new class was added to better handle the breakpoint
	classes. This new class, AliasedInstruction, is a base for the
	breakpoint class and basically will provide an API to handle
	aliased or replace instructions.

2005-09-11 Scott Dattalo <scott@dattalo.com>
	* plat/win32/gpsim.def: updated for API changes.

2005-09-11 Scott Dattalo <scott@dattalo.com>

	FormatProgramAddress() functions in IUserInterface and
	CGpsimUserInterface.

2005-09-09 Scott Dattalo <scott@dattalo.com>

	* configure.ac, plat/win32/gpsim.nsi: bump build number

	* gui/gui_src_asm.cc, src/value.cc: Fixed crashes when
	'Add to watch' menu item is selected with no test selected
	or with white space selected.

2005-09-07 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_load.cc: null pointer fix (was causing core dump in the
	regression test).
	* module/usart.cc: added the TxBuffer attribute.
	* regression/usart_test/usart_test.cc: tested usart module transmitter.

2005-09-07 J.R. Heisey <jrheisey@sourceforge.com>

	gui_regwin.h, gui_watch.cc, gui_main.cc: Changed Register_Window::
	registers from type GUIRegister* to GUIRegisterList*.
	Added GUIRegisterList * m_pGUIRegisters to GUI_Processor.
	Now GUIRegisters are instantiated in a GUI_Processor for
	that other windows besides the RAM_RegisterWindow. This
	fixes a bug where you cannot add a register symbol to the
	watch window unless the RAM_RegisterWindow was opened
	once.

	* gui/gui_src_asm.cc, gui/gui_watch.cc: Removed 'Select symbol'
	pop up menu item since it was broken anyway. Added 'Add to watch'
	pop up menu item. Select symbol text in the source window, selecting
	'Add to watch' will add register symbols to the Watch window.

	* src/symbol.cc, src/symbol.h: Added findRegisterSymbol() that
	accepts a const char * as a parameter.

	gui/gui_main.cc: Call new function GUI_Processor::SetCPU() from
	GUI_Interface::NewProcessor(). SetCPU() does some additional
	initialization.

	* src/value.cc, src/value.h: Added toupper(string&) function.

	* gui/gui_src_asm.cc: Changed to use new toupper() function
	due to issues between Windows and Linux.

	* src/operator.cc: quite some type mismatch warning messages

2005-09-02 Manuel Bouyer <bouyer@antioche.eu.org>
	* src/16bit-registers.cc: PCL accesses were using program memory
	indexes instead of program memory addresses.
	* src/14bit-tmrs.cc: TMR2:current_value() would return the
	contents of PR2 even when configured for normal operation.
	* src/p18x.cc: typo in porte names.

2005-09-01 Manuel Bouyer <bouyer@antioche.eu.org>
	* src/p18x.cc: Fix crash when an 18F252	is instantiated.

	option is used.

2005-08-30 J.R. Heisey <jrheisey@sourceforge.com>
	* cli/input.cc: Created function parse_string_only() which
	will parse the passed in command string with out emptying
	existing commands from the buffer.
	Modified LLStack::GetNext() and LLStack::Pop() to not remove
	the last LLStack object.
	Fixed memory leak in LLStack::Pop().

	* cli/ui_gpsim.cc: Added EOL to injected abort_gpsim_now
	command.

2005-08-30 Scott Dattalo <scott@dattalo.com>
	* src/gpsim_time.h, src/gpsim_time.cc, bitlog.cc: Made the
	constant 'END_OF_TIME' part of the Cycle_Counter class. This is
	now used to initialize members of the ThreeStateLogger class.

2005-08-30 Scott Dattalo <scott@dattalo.com>
	* src/processor.h, src/processor.cc, src/pic_processor.cc: Fixed
	step-over feature for the 18F family.

2005-08-30 Scott Dattalo <scott@dattalo.com>
	* regression/rt.sh: The new version of the regression test script
	was not checked in yesterday. This new version creates a simple
	stc file and invokes a single regression test. It then checks to
	see if the test was successful.
	* regression/simulate, regression/create_stc: Removed from CVS.

2005-08-29 J.R. Heisey <jrheisey@sourceforge.com>
	* src/ioports.cc, src/ioports.h: Added PortModule::getPin().

	IOPIN::update_direction method now has a refresh option.
	* src/ioports.h, src/ioports.cc:
	- Added several options to control when I/O pins refresh their state
	  information (with respect to stimuli that is).
	- PicPortBRegister::get () had the wrong parameter signature and
	thus was not getting invoked (the parent get() method was getting
	invoked instead).
	* modules/usart.cc: updating to new iopin api. Added new code and
	removed a bunch dead code and generally cleaned things up - it's
	still not working yet though.
	* src/12bit-processors.cc, src/12bit-processors.h, src/p16f62x.cc:
	pic-processor.cc, pic-processor.h, processor.h
	set_config_word now returns true if the config word address is
	successfully set.
	* src/pic-processor.cc: Fixed bug with
	init_program_memory_at_index() - it was not setting the
	configuration word if the address was in configuration memory.
	* src/bitlog.cc: Added a 'ThreeStateEventLogger' that's analogous
	to the bit and byte logger.
	* src/intcon.cc: Turned off some debugging code.
	* src/registers.h: fixed typo in comment
	* src/stimuli.cc, src/stimuli.h: Iopin's were checking Z state
	before W state - this caused a W-state condition to be returned as
	a Z-state. In addition, the getDrivingState() was being checked as
	opposed to the getDrivenState().
	- Added getMonitor() method.
	* src/uart.h, src/uart.cc: Updating to new I/O pin design. And
	numerous changes to clean up and fix the code - this is still not
	working though.

2005-08-23 Scott Dattalo <scott@dattalo.com>
	* run_regression.sh, rt.sh: Redesigned the regression tests to
	make use of new gpsim scripting features. Also, all tests have

	* cli/input.cc, cli/input.h, gpsim/main.cc: Added two
	command options. Option -E will echo commands to the
	console. Useful for stc debugging. This will also
	display all the command line parameters. Useful when
	another tool launches gpsim but does not display the
	command line.

	gpsim/main.cc, src/init.cc: Option '-S disable' will
	prevent source code from being loaded. Usefule for
	automated regression testing. '-S enable' will enable
	source code loading. See online help.

	* src/p16x7x.cc: Fixed an sign/unsigned warning.

	* src/processor.h: Test function for whether source file
	is open.

	* src/sim_context.cc, src/sim_context.h: Added new
	global boolean property called EnableSourceLoad. Setting
	it to false will prevent source code from being loaded.
	Purpose is when gpsim is used for automated regression
	testing to speed things up.

	* src/stimuli.cc: Fixed a crashing bug when port()
	operator is used with out any module explicitly entered
	as a parameter.

	* src/symbol.h, src/value.h: Added findBoolean() to
	Symbol_Table.

	that accepts a parameter onbreak. This causes gpsim to
	exit when the simulation halts.

2005-08-11 Scott Dattalo <scott@dattalo.com>
	* src/breakpoints.cc, src/breakpoints.h: Allowed breakpoint
	expressions for breakpoint instructions to act like assertions.

	  src/modules.cc, src/modules.h, cli/input.cc:
	Added the capability to run multiple module scripts.
	* cli/ui_gpsim.cc: Fixed bug guint64 formatted output.
	* regression/logic_test/Makefile, regression/logic_test/logic_test.asm:
	The new I/O port design more correctly implements I/O pins and
	this exposed a bug in the regression test. Also, this regression
	test was used to develop the multiple Module Script feature.

2005-08-11 J.R. Heisey <jrheisey@sourceforge.com>
	* src/stimuli.cc, src/stimuli.h, src/symbol.cc, src/symbol.h:
	Quick fix of when trying to attach an input data stimuli that
	was broken a couple of checkins ago.

2005-08-11 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.nsi: bump build number

2005-08-11 Scott Dattalo <scott@dattalo.com>
	* src/ioports.cc, src/ioports.h: Added the PeripheralSignalSource
	class to simplify the connection of I/O pins to peripherals. Also,
	added more documentation about the I/O port design.
	* src/p16x7x.h, src/p16x7x.cc, src/p16f87x.cc: The Analog to
	Digital convertor peripheral now connects to I/O pins again. Also,
	the A2D module was redesigned so that less of the internal
	implementation is exposed.
	* src/14bit-tmrs.h, src/14bit-tmrs.cc, src/ssp.h, src/ssp.cc,
	src/p16x6x.cc: Updated the peripheral connections with the new
	PeripheralSignalSource class.

2005-08-10 J.R. Heisey <jrheisey@sourceforge.com>
	* src/stimuli.cc, src/stimuli.h, src/symbol.cc, src/symbol.h,
	cli/cmd_attach.cc, cli/cmd_attach.h, cli/parse.yy,
	cli/scan.ll, plat/win32/gpsim.def: Modified
	the attach command with the pin() and port() operators.
	Now you can use one of 4 variations of these operators to
	specify the module, port name and/or pin number that represents
	the underlying stimulus object. An example of how to use: if
	a pin number is defined as a program file symbol, you
	may use the symbol name in the port() or pin() operators.
	This way your STC file can be more generic and support a
	variety of firmware code files as long as you use the same
	symbol name for the pin. See the online help for more details.

	The pin() operator refers to package based pins. The port()
	operator refers to port based pins. Other stimulus may still
	be refered to using just the name of the stimulus.

	* src/attributes.cc: Changed a few global symbols so that
	Symbol_Table::Clear() does not remove them.

	* src/fopen-path.cc, src/fopen-path.h, gpsim/main.cc:
	Fixed -L source path command line option.
	Added code to support a gpsim SourcePath global string symbol
	that give command prompt access to the source search path.

	* src/ioports.h: Fixed a warning message about the destructor
	of PinModule not being virtual.

	* src/symbol.cc,h, cli/cmd_symbol.cc: Added the ability to
	use the '.' character as a trailing wild card in the symbol
	command. Example PIC. will list all symbols that begin with
	the letters PIC.

2005-08-04 Scott Dattalo <scott@dattalo.com>
	* gui/gui_breadboard.cc, src/symbol.h, src/symbol.cc,
	src/stimuli.cc:
	Verified that template issues with gcc 3.4.X have been resolved
	and removed a #define that had beed added to get around this.

2005-08-06 Scott Dattalo <scott@dattalo.com>
	* src/ssp.h, src/ssp.cc: Updated the SSP peripheral with the new
	I/O port API.
	* src/14bit-processors.h, src/p16f87x.cc, src/p16f87x.h,
	src/p16x6x.cc, src/p16x6x.h, src/p16x7x.cc, src/p16x7x.h: Updated
	to the new SSP API.

2005-08-04 J.R. Heisey <jrheisey@sourceforge.com>
	* symbol.cc, symbol.h: Fixed the template compile problems for
	gcc 3.4.4 due to new bugs in gcc. I didn't see this issue using
	gcc 3..3.3 on linux. I only have 3.4.4 version of the compiler
	under cygwin. I've left the #define commented out so someone can
	test it under linux before removing the #ifdef's.

2005-08-04 Scott Dattalo <scott@dattalo.com>
	* gui/gui_breadboard.cc, src/symbol.h, src/symbol.cc, src/stimuli.cc:
	Backed out some of the symbol changes made by JR because the code
	doesn't compile on Linux (gcc 3.4.2). At the moment, this means
	that stimuli and node dumps do not work.

2005-08-04 J.R. Heisey <jrheisey@sourceforge.com>
	* cli/cmd_node.cc, plat/win32/gpsim.def, gui/gui_breadboard.cc,
	modules/resistor.cc, src/stimuli.cc, src/stimuli.h,
	src/symbol.cc, src/symbol.h, src/value.h: Eliminated the
	node_list and stimulus_list. There are now Symbol_Table
	functions and iterators available for node_symbol and
	stimulus_symbol objects which contain Stimulus_Node and
	stimulus objects respectively.
	Adjusted the way stimulus and stimulus_Node objects are
	named. Unnamed objects are not put into the symbol table.
	The respective new_name() functions will add the objects
	into the symbol table appropriately. Removes several
	references that added these objects to the symbol table.

	Also modified the PullupResister to name the res IO_bi_directional
	i/o pin to pullupname + ".pin". Now the PullupResister
	exists in the symbol table as a module with what ever you
	named it. The pin is attribute of the PullupResister module.
	Whew!

2005-08-04 Scott Dattalo <scott@dattalo.com>
	* src/uart.cc, src/uart.h, src/p16x6x.cc, src/16bit-processors.cc,
	src/16bit-registers.cc, src/16bit-registers.h, src/p16f62x.cc:
	Add I/O source and sink connections to the usart peripheral. So
	now the usart is connected to I/O pins using the new I/O port design.

2005-08-02 J.R. Heisey <jrheisey@sourceforge.com>
	* src/os_dependent.cc, src/processor.cc,h, src/cod.cc,
	plat/win32/gpsim.def: Fixed a problem where loading a
	program file (no STC) using the GUI resulted source code
	not being found even though that source was in the same
	folder as the program file.

	* gui/gui_menu.cc: Fixed the display of cycle count in
	cycles where %Lx was used in a sprintf instead of the
	platform independent project macro PRINTF_INT64_MODIFIER.

2005-08-02 Scott Dattalo <scott@dattalo.com>
	* src/16bit-processors.cc, src/p18x.cc: The new I/O port register
	symbols were getting added to the symbol table twice. Also, the
	eeprom peripheral for some of the 18f devices was not getting
	created.

2005-08-02 J.R. Heisey <jrheisey@sourceforge.com>
	src/cmd_gpsim.h
	* src/cod.cc: Removed an error message from PicCodProgramFileType::
	open_a_file() that is handled externally.

	* src/registers.cc: Fixed a bug in RegisterValue::toString()
	not displaying enough digits.

	* src/value.h, src/symbol.h, src/registers.h, gui/gui_register.h:
	Added some conversion and equals operators.

	* cli/ui_gpsim.cc, src/cmd_gpsim.h: Added several string
	formatting routines.

	* plat/win32/gpsim.def: Updated for new pin I/o routines.

	* gui/gui_watch.cc, gui/gui_watch.h: Updated display of values
	to account for uninitialized bits and bit masked register
	symbols.

2005-08-01 Scott Dattalo <scott@dattalo.com>
	* src/p16x5x.h, src/p16x5x.cc: Upgraded the P16C54 and P16C55 to
	the new I/O port design.

	* src/16bit-processors.cc, src/16bit-registers.cc,
	src/16bit-registers.h, src/p18x.cc, src/p18x.h:
	Completed converting the 16-bit core I/O ports to the new I/O
	redesign (note - the peripheral-to-I/O mapping still needs to be
	completed).

	* src/ioports.h, src/ioports.cc: deprecated the old PIC_IOPORT
	class and all of its children.

2005-08-01 Scott Dattalo <scott@dattalo.com>
	* src/14bit-processors.cc, src/14bit-processors.h,
	src/14bit-tmrs.cc, src/14bit-tmrs.h, src/intcon.cc, src/intcon.h,
	src/pir.h, src/p16x6x.cc, src/p16x6x.h, src/ioports.cc,
	src/ioports.h, src/p16x7x.cc, src/p12x.cc:

	-- The intcon and pir registers were not getting set up correctly for
	   the midrange devices.
	-- Added 'sinks' and 'sources' for the CCP module.

	* src/16bit-processors.cc, src/16bit-processors.h, src/p18x.cc,
	src/p18x.h: Began porting the new I/O port design to the 16bit
	core devices.

	* src/symbol.cc: Added a diagnostic message that is printed
	whenever a register symbol with a null cpu is added to the symbol
	table.

	* regression/run_regression.sh, regression/p18f452_ports.asm,
	regression/p18f452_ports.stc:
	-- Added new regression test to test the P18F family I/O ports.
	-- Redesigned the processor construction sequence.
	-- The P18F1220 did not have PortB pullup resistors.

2005-07-30 J.R. Heisey <jrheisey@sourceforge.com>
	* src/symbol.cc, src/symbol.h: Added a list of symbols
	that are defined from the gpsim command line. The list
	and the symbol values are preserved when the symbol table
	is cleared due to a new processor being allocated.
	Removed the add() function that accepted a symbol type
	as a string. See comments for cmd_symbol.cc,h.

	* src/attributes.cc, src/sim_context.cc, src/sim_context.h:
	Changed or added calls to the symbol table.

	* cli/ui_gpsim.cc, src/cmd_gpsim.h: Added functions to render
	integer values to strings based on a system level defined
	radix. The radix will be exposed as a global attribute.
	There are distinct radix definitions for program addresses,
	RAM addresses and data values. Will expose a global attribute
	to define the prefix for displaying hexidecimal values. The
	default is '$'.

	* gpsim/main.cc: Added -D command line option for defining
	symbols and their values to be placed into the symbol
	table.

	* src/value.cc, src/value.h: Added string parsing and
	constructor functions for each data type. Used for
	the command line parsing of symbol definitions.

	* cli/cmd_symbol.cc,h, cli/cmd_load.cc,h, cli/parse.yy:
	The load command will now accept symbols as input for the
	filename. Combined with	the symbol defines on the command
	line, one STC file can be used to open any program file by
	defining a symbol on the gpsim command line and referencing
	that symbol in the load commmand.
	* The symbol command can now be used to create a symbol from
	the gpsim command prompt or an STC file. The syntax is
	symbol <newsymbol>=<value>. Types include string, integer,
	float and boolean.

	* gpsim/gpsim.vcproj, gui/gui_menu.cc, gui/gui_regwin.cc:
	Removed the references for gtk_file_selection_get_filename_utf8().
	This was added due to compile time issues with gtkextra-2.1
	under Visual Studio .NET. The VS.NET build links a gtkextra
	static lib into the exe. Even if you can get it to compile,
	sometimes gpsim will crash before its main() function is
	entered. The use of gtkextra-2.1 under VS.NET is not
	recommended and I have reverted the gpsim.vcproj back to
	gtkextra-2.0.

	* src/program_files.cc: Changed error handling logic
	to prevent a "list file not found" error from displaying
	in an inappropriate situation.

2005-07-29 Scott Dattalo <scott@dattalo.com>
	* src/ioports.cc, src/ioports.h, src/p12x.cc, src/p16x6x.cc,
	src/registers.h, src/stimuli.cc, src/stimuli.h, src/symbol.cc,
	src/tmr0.cc, src/tmr0.h:
	Introduced the concept of Multi-State logic to stimuli.


2005-07-15 J.R. Heisey <jrheisey@sourceforge.com>
	* src/symbol.cc: Added check to prevent a symbol name of a null string
	from being added as a symbol.

	* src/stimuli.cc: Added a check to prevent a IOPIN name null string
	pointer	from being added to the symbol table.

	* modules/resistor.cc: PullupResistor() constructor was setting
	its attribute before it had set its own name resulting in the
	attribute name not being scoped correctly.

	* src/breakpoints.cc, src/breakpoints.h, cli/cmd_break.cc,
	cli/cmd_break.h: Added code to support break expressions of
	the form (Reg & mask BoolOp value) where BoolOp includes
	<, >, <=, >= and != operators. Just need to change the print()
	and action() console output functions of the break classes and
	uncomment code in parse.yy.

2005-07-26 Scott Dattalo <scott@dattalo.com>
	* src/bit.h, src/bit.cc, src/Makefile.am: Added new files to
	handle a 'Bit' object. This code was formerly tucked away in
	registers.cc.
	* src/stimuli.h, src/ioports.h, src/ioports.cc: Added a control
	object for the PinModule to handle I/O pin pullups. Also, added an
	option to prohibit certain stimulus updates whenever I/O pin state
	information changes.

2005-07-26 Scott Dattalo <scott@dattalo.com>
	* src/16bit-instructions.cc,
	regression/instructions_16bit/instructions_16bit.asm: Fixed bug
	with 16bit processors Table Read (more index vs address). Thanks
	to Peter Onion for pointing this (and other 16bit stuff out).

2005-07-26 Scott Dattalo <scott@dattalo.com>
	* src/i2c-ee.cc, src/i2c-ee.h, src/ioports.cc, src/ioports.h,
	src/p12x.cc, src/stimuli.cc, src/stimuli.h: Fixed 12CE51x internal
	eeprom peripheral.
	* gui/gui_menu.cc, gui/gui_regwin.cc: Removed dependency on gtk
	win32 port.

2005-07-25 Scott Dattalo <scott@dattalo.com>
	* regression/instructions_16bit/instructions_16bit.asm: added
	tests for multi-word instructions.
	* regression/p12ce518/p12ce518.asm: debugging eeprom i2c interface
	* gui/gui_src_opcode.cc, src/16bit-instructions.cc,
	src/16bit-instructions.h: Fixed more problems with address <-->
	index mapping. (and there are still some issues remaing with the
	program memory viewer).
	* src/i2c-ee.cc, src/ioports.cc, src/ioports.h, src/p12x.cc,
	src/p12x.h: The eeprom i2c interface is broken...

2005-07-23 Borut Razem <borut.razem@siol.net>
	* gpsim/gpsim.vcproj, doc/gpsimWin32.html, plat/win32/gpsim.nsi:
	  use pthreads-w32-2-7-0-release
	* cli/scan.ll: corrected typo

2005-07-22 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_disasm.cc: rnages were disassembling wrong addresses
	* gui/gui_src_asm.cc: cleanup
	* src/12bit-processors.cc, src/14bit-processors.cc,
	  src/14bit-registers.cc, src/14bit-tmrs.cc, src/attributes.cc,
	  src/gpsim_classes.h:
	Implenting new ioport design for 12bit cores.
	Fixed bugs with resets.
	* src/16bit-hexdecode.cc, src/16bit-instructions.cc,
	  src/16bit-processors.h, src/16bit-registers.cc, src/cod.cc:
	16bit processors were not getting loaded properly due to some
	bugs with address <-> index mapping

2005-07-21 Scott Dattalo <scott@dattalo.com>
	* src/ioports.h, src/ioports.cc: classes derived from PortRegister
	can now specify the type of PinModule class.

2005-07-15 Scott Dattalo <scott@dattalo.com>
	* src/12bit-processors.cc, src/14bit-processors.cc,
	src/14bit-processors.h, src/16bit-registers.cc,
	src/16bit-registers.h, src/intcon.h, src/ioports.cc,

	src/registers.cc, src/registers.h, src/stimuli.cc, src/stimuli.h,
	src/tmr0.cc, src/tmr0.h, src/uart.cc, src/uart.h:

	I/O Port Redesign: These files have been updated to accommodate a
	new I/O Port design. Currently the design applies only to the
	mid-range PIC family, but will be propogated to the 12 and 16 bit
	cores too.

	In summary, the I/O pins are now managed with I/O pin modules. A
	port register maintains an array of these modules. In the old
	design, the I/O pins were managed directly by the Port
	registers. New classes have been designed to allow multiple signal
	sources, signal controls, and signal sinks for I/O pins. These new
	objects can be added at will and thus allow the exact behavior of
	an I/O pin be tailored to a specific processor (and even changed
	dynamically). Thus a base class in the processor heirarchy can
	instantiate a register object, and the derived processors populate
	it with custom functionality.

	* cli/cmd_break.cc: documentation clean up
	* modules/usart.cc, modules/usart.h: tinkering -
	* regression/logic_test/Makefile,
	regression/logic_test/logic_test.asm: Incorporates an un-released
	gpasm feature of the .direct macro. This feature allows multiple
	strings to be passed to gpasm.
	* regression/p16f84/p16f84.asm: Bug fix in PORTB pullup test


2005-07-15 J.R. Heisey <jrheisey@sourceforge.com>
	* gui/gui_watch.cc, gui/gui_watch.h: Fixed problem with
	register symbol names not displaying in the Watch
	window. Introduced this	bug when I made the bit mask feature
	in register symbols.

	* gui/gui_regwin.cc:  Fixed problem with register symbol
	names not displaying in the RAM window. Introduced this
	bug when I made the bit mask feature in register symbols.

2005-07-11 J.R. Heisey <jrheisey@sourceforge.com>
	* src/breakpoints.cc, h, src/cmd_gpsim.h, src/symbol.cc,
	plat/win32/gpsim.def, gpsim/main.cc, cli/ui_gpsim.cc,
	cli/ui_gpsim.h: Made changes so that when hitting a
	break will display program and register address symbols.

	* src/breakpoint.cc: Removed calls to eval_Expression()
	where it is not necessary. Enhanced the break on value
	action text to include symbols and bit mask value.

	* cli/ui_gpsim.cc,h, gpsim/main.cc: Added functions that
	help display program and register address symbols along
	with the address value.

	* src/trigger.cc: Fixed problem in TriggerObject::
	eval_Expression() that was preventing non-expression
	based break points to not fire.

	* src/symbol.cc: Added check in Symbol_Table::
	findRegisterSymbol() to get register bit mask defined
	for the CPU when the passed in value is zero.


2005-07-10 J.R. Heisey <jrheisey@sourceforge.com>
	* plat/win32/gpsim.def, src/symbol.cc, src/symbol.h:
	Change function name from findRegister() to findRegisterSymbol()
	to reflect the return type. Added new findRegisterSymbol()
	version that takes a single address parameter. Did some
	minor code optimization of the findRegister() function.
	Due to the introductions of register symbol bit mask, I
	modified findRegister() to only return symbols that are
	defined for all bits of the register.

	* src/processor.cc: Changed some entry condition checks to
	allow processor::disassemble to disassemble one program
	address. Also made some minor code optimizations.

2005-07-06 Borut Razem <borut.razem@siol.net>
	* src/breakpoints.cc, src/gpsim_time.cc, src/interface.cc, src/processor.src, src/trace.cc:
	  declare dummy_bp, dummy_cycles, dummy_gi, dummy_get_active_cpu, dummy_set_active_cpu
	  and dummy_trace as non static to compile with gcc 3.4.4
	* plat/win32/gpsim.nsi: corrected version number to 0.21.8
	* gpsim/gpsim.vcproj, gpsim/makefile.mingw: linking with libgtkextra-win32-2.1.lib
	* doc/gpsimWin32.html: linking with gtk+extra-2.1.1, glib-2.6.5,
	  gtk+-2.6.8, pango-1.8.0, 1.9.0, fontconfig-2.2.2-20040412
	* plat/win32/make.mingw: change gcc command line options mcpu with mtune
	  to compile with gcc 3.4.4

2005-07-08 J.R. Heisey <jrheisey@sourceforge.com>
	* plat/win32/gpsim.def, src/symbol.cc, src/symbol.h:
	Added version of Symbol_Table::findRegister() that takes a bitmask
	parameter. Added Symbol_Table::findConstant() for future use.
	Need to implement a symbol to referenced from address
	cross reference.

	* gui/gui_src_opcode.cc, src/processor.cc: Fixed issues
	accessing program memory arrays using address instead
	of an appropriate index.

	* gui/gui_src_opcode.cc, src/processor.cc: Fixed issues
	with Processor::disassemble() function not traversing
	over break points to find the base instruction object.


2005-07-07 J.R. Heisey <jrheisey@sourceforge.com>
	* cli/cmd_break.cc, cli/cmd_break.h: Code to display
	address labels in break related messages.

	* plat/win32/gpsim.def, src/pic-instructions.cc,
	src/pic-instructions.h,	src/processor.cc, src/processor.h,
	src/symbol.cc: Code to display address labels in a
	disassembly output. Added members to Processor class to
	support a page mask and offset mask that can be used to
	calculate absolute addresses for disassembly output for
	JUMP and CALL instructions. See the functions
	CalcJumpAbsoluteAddress() and CalcCallAbsoluteAddress();

2005-07-06 J.R. Heisey <jrheisey@sourceforge.com>
	* src/stimuli.cc, src/symbol.cc, src/symbol.h:
	Fixed a problem where renamed stimulus_symbol objects
	were getting lost. This caused a error when running
	the regression test digital_stim.

2005-07-06 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.nsi: NSIS 2.07 compatible

2005-07-05 J.R. Heisey <jrheisey@sourceforge.com>
	* src/symbol.cc, h: The access to a derived object's name()
	function was broken when I made the name() function in the
	base class const. I've propogated the const attribute to
	overriden versions of name().
	- Somewhere along this process on of my program variables stopped
	being added to the symbol table. So, I've changed the if statement
	that determines when a duplicate variable exists in the symbol
	table.
	- I've added a function called findProgramAddressLabel() so
	that a label name can be displayed where appropriate.

	* src/breakpoints.cc: Changed ::print() functions to output
	program memory labels where they could. Changed implementation
	to use the Console object rather than cout.

	* src/registers.cc: InvalidRegiser() constructor was not setting
	its address member variable. Now the address is included in the
	console warning.

	* src/attributes.cc: WarnModeAttribute() was not setting its
	value member variable.
	-  init_attributes() added some constant attributes for reset types.

2005-07-01 Scott Dattalo <scott@dattalo.com>
	* cli/scan.ll, cli/parse.yy, cli/input.cc: The recently added
	command line error processing change did not compile under Linux
	and was free a constant pointer.
	* gui/gui_main.cc, gpsim/main.cc: The command line prompt was
	always selected.

2005-07-01 J.R. Heisey <jrheisey@sourceforge.com>
	* cli/scan.ll, cli/parse.yy, cli/input.cc,h:
	- Full command line text is displayed when a command line error
	occures.
	- Command line buffers are cleared appropriately after a command
	line error.

2005-06-30 Scott Dattalo <scott@dattalo.com>
	* regression/logic_test/logic_test.asm,
	regression/logic_test/Makefile, regression/logic_test/16f873.lkr:
	Added a regression test for gpsim Logic Modules.

2005-06-30 J.R. Heisey <jrheisey@sourceforge.com>
	* src/breakpoints.cc, src/breakpoints.h, cli/cmd_break.cc:
	New break point dump filtering.
	break r dumps register read break points.
	break w dumps register write break points.
	break e dumps execution break points.

	* cli/cmd_disasm.cc: Updated disassemble command on line help
	to reflect reality.

2005-06-30 Scott Dattalo <scott@dattalo.com>
	* cli/input.cc, gpsim/main.cc, gui/gui_main.cc,
	src/gpsim_interface.h, src/interface.cc, src/modules.cc,
	src/modules.h, src/processor.cc:
	Added methods to the gpsim_interface class that manage the state
	of gui. This is done so that gui-based modules can query the gui
	state and conditionally build their graphical portions.
	* modules/led.cc, modules/logic.cc:
	The Logic and LED modules now will not build any graphics if the
	gui is not initialized.
	Pin names were getting added to the symbol twice.

2005-06-27 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.cc, src/stimuli.h:
	Added putState()/getState() methods and removed putDrivingState
	method from the stimulus class. The purpose of this is to abstract
	away whether a node is driving or not. The main affect is in the
	gui breadboard where the state of I/O pins is queried.
	* gui/gui_breadboard.cc, gui/gui_breadboard.h, modules/usart.cc,
	modules/video.cc, modules/video.h, src/14bit-tmrs.cc,
	src/i2c-ee.cc, src/ssp.cc,
	src/uart.cc: Updated calls to new stimulus class API.
	* modules/logic.cc, modules/logic.h: The logic gate modules had
	bit rotted.

2005-06-26 J.R. Heisey <jrheisey@sourceforge.com>
	* plat/win32/gpsim.def, src/processor.cc, src/processor.h:
	New function Processor::init_program_memory_at_index() to
	continue the separation of PM address from PM array index.

2005-06-26 Scott Dattalo <scott@dattalo.com>
	* src/trace.cc: The wrong variable was being used to index the
	program counter array. This caused the trace to get an invalid
	instruction.

2005-06-26 Scott Dattalo <scott@dattalo.com>
	* INSTALL: Added notes from Bas Wijnen regarding Debian.

2005-06-25 Scott Dattalo <scott@dattalo.com>
	* src/symbol.cc, regression/simulate: The new 'BITS' indicator for
	register symbol queries broke the regression test. Now, the BITS
	indicator is only displayed if only a portion of the register
	applies to a register symbol.

2005-06-24 J.R. Heisey <jrheisey@sourceforge.com>
	* src/modules.cc: Fixed a bug in Module::get() where
	a derive class does not override this function, now
	this function will return a null string.
	This fixes problems when a derived class is being
	displayed in the GUI symbol window causing a UTF-8
	warning.
	* src/symbol.cc: Fixed an introduced null pointer
	exception.

2005-06-23 J.R. Heisey <jrheisey@sourceforge.com>
	* plat/win32/gpsim.def, src/symbol.cc, src/symbol.h:
	register_symbol::m_uMask is used to mask out bits not
	associated with the symbol after retrieving the value
	from the register. Masked bit values are right shifted such
	that if the 16th bit is high in the register and
	m_uMask = 0x80, then the symbol value returned
	or displayed will be one.
	Likewise to set the 16th bit of our example register_symbol
	you would set the register_symbol value to 0x01 and
	not 0x80. No other bits in the register are changed.
	It works as if this symbol is its own register. The encoding
	into the target register is hidden by register_symbol.
	The default value of m_uMask is 0xff so that no bits are
	masked out.
	An new version of Symbol_Table::add_register() may be used
	to add masked register_symbol objects to the symbol table.
	register_symbol::copy() is changed to return the correct
	symbol string.

2005-06-21 J.R. Heisey <jrheisey@sourceforge.com>
	* cli/cmd_run.cc: Added help text saying that CTRL->C
	will stop a running simulation.

	* src/breakpoints.cc, src/processor.cc, src/processor.h,
	src/trace.cc, plat/win32/gpsim.def, gui/gui_profile.cc,
	gui/gui_src_asm.cc:
	There was significant ambiguity for some functions
	that appear to accept an simulation address but acted upon
	it as a ProgramMemoryAccess index. The ProgramMemoryAccess
	indexing operator was a prime example. I have eliminated
	the indexing operator and added the functions getFromAddress()
	and getFromIndex() to make things more explicitly clear.
	I have also removed put() and get() and added putToAddress()
	and putToIndex(). Other new functions are
	hasValid_opcode_at_address() and hasValid_opcode_at_index().
	This mostly effected gui code so the simulation itself
	should have no impact.
	The original intent of this change was to fix bugs in the
	gui where double clicking on a breakpoint icon in the
	source window would not toggle the breakpoint.

2005-06-17 J.R. Heisey <jrheisey@sourceforge.com>
	* cli/cmd_dump.cc: dump register for special registers
	broken when pReg->isa() and Register::SFR_REGISTER were
	not being used. Now we dump the registers listed in
	MemoryAccess::SpecialRegisters.

	* cli/input.cc: Implemented the	ability to break running
	firmware using Ctrl->C key when running under Windows.
	It would previously exit gpsim.

	* gpsim/main.cc: Changed logic so the -i on the gpsim
	command line will not attempt to start the gui interface.

	* cli/cmd_break.cc, cli/cmd_clear.cc, cli/cmd_disasm.cc,
	cli/cmd_dump.cc, cli/cmd_frequency.cc, cli/cmd_help.cc,
	cli/cmd_load.cc, cli/cmd_module.cc, cli/cmd_processor.cc,
	cli/cmd_step.cc, cli/cmd_stimulus.cc, cli/cmd_trace.cc,
	cli/cmd_version.cc, cli/command.cc, cli/command.h:
	Implemented command abbreviations. Made abbreviations for
	several often used commands.

2005-06-14 J.R. Heisey <jrheisey@sourceforge.com>
	gui/gui_src.h, gui/gui_src_asm.cc, gui/gui_statusbar.cc,
	src/processor.cc, src/processor.h, src/registers.h:
	Fixed some problems with the source window optimization.
	Fixed problem with the text search dialog not searching
	alternate source windows.
	Fixed problem with Set PC Here from an alternate window.

2005-06-13 J.R. Heisey <jrheisey@sourceforge.com>
	*src/cmd_manager.cc, src/cmd_manager.h, src/modules.cc,
	cli/cmd_shell.cc: Fixed introduced bug where the command
	line interface from a library module was not accessible.
	A ! bang character alone lists the command line interfaces.

2005-06-13 Scott Dattalo <scott@dattalo.com>
	* configure.ac: Fixed recently introduced typo.
	* src/attributes.cc: Cycle counter attribute now prints correctly again.
	* src/processor.cc, src/processor.h: fixed bug in
	IsAddressInRange()  method, also reversed return value to match
	meaning of name (now returns true if the address is in range).
	* src/symbol.cc: Symbol table dump was not showing symbol values.
	* src/registers.cc: fixed warning message for when invalid
	registers are accessed.

2005-06-10 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.cc, src/stimuli.h, src/symbol.cc, src/symbol.h:
	Stimuli symbols were not getting added to the symbol table when
	their name was being changed.

2005-06-10 J.R. Heisey <jrheisey@sourceforge.com>
	*src/gpsim_object.cc,h: Small change to allow name() call
	in a const variable context.

	*plat/win32/gpsim.def, src/processor.cc, src/stimuli.cc,
	src/symbol.cc, src/symbol.h, gui/gui_profile.cc: Changed
	the implementation of the Symbol_Table class to order
	by symbol name so that a binary search will improve lookup
	speed.

2005-06-10 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_stimulus.cc, doc/gpsim.lyx: Updated documentation.

2005-06-09 J.R. Heisey <jrheisey@sourceforge.com>
	*cli/cmd_module.cc: Added extra help for module command.

	*gui/gui_src.h, gui/gui_src_asm.cc, plat/win32/gpsim.def,
	src/processor.cc,h: Changed the parsing of the source for
	formatted display to speed things up during file loading.
	Source is now cached in a form for rendering to the formatted
	text window.

2005-06-09 Scott Dattalo <scott@dattalo.com>
	* gui/gui_main.cc, gui/gui_regwin.cc, gui/gui_src.cc,
	gui/gui_src_asm.cc, gui/gui_src_opcode.cc, configure.ac:
	Found the source of a bug that causes gpsim to hang when gtk-2.6.7
	and gtkextra-2.0 are used. The problem is either with gtkextra or
	the interaction of it with gtk. gpsim currently has in place a
	stop-gap measure to prevent the problem from keeping the simulator
	from being unusable.

2005-06-06 J.R. Heisey <jrheisey@sourceforge.com>
	*src/os_dependent.cc: The environment variable GPSIMPATH may be
	used to specify folders where shared libraries may be found. This
	is primarily for windows developers of gpsim.
	- Small change to prevent load_library() from displaying an error
	message that is not needed.

	*cli/cmd_node.cc: Use a reference instead of allocating a string
	on the local stack.

	*modules/modules.vcproj: Changed Visual Studio build of modules
	to libgpsim_modules.dll


2005-06-04 Scott Dattalo <scott@dattalo.com>
	* gui/gui.h, gui/gui_menu.cc, gui/gui_object.cc, gui/gui_object.h,
	gui/gui_src_asm.cc, gui/gui_statusbar.cc, gui/gui_statusbar.h:
	-- removed the cycle counter and time view from the status bar of
	the register and source windows and moved them to the window that
	contains the buttons.
	-- fixed text-width bugs in the status window.
	-- rewrote the implementation of the gui update code.
	-- Created a 'TimeWidget' class and a 'TimeFormatter' class for
	displaying the cycle counter object.
	-- Added a MainWindow class (kind of empty now).
	-- Re-introduced a few of the GTKWAIT macros.

2005-06-04 Scott Dattalo <scott@dattalo.com>
	* configure.ac, gpsim/Makefile.am: remove the explicit checks for
	the pthread library.

2005-06-04 Scott Dattalo <scott@dattalo.com>
	* gpsim/main.cc: Allow filenames whose first character is a
	number.

2005-06-04 Scott Dattalo <scott@dattalo.com>
	Patch from: Rob Pearce <rob@bdt-home.demon.co.uk>
	* src/cod.cc: Fixed gramatical error.
	* src/eeprom.cc, src/eeprom.h: Added a new state to the eeprom
	state machine to fix ??
	* src/ioports.cc: fix to the 628 porta comparator.

2005-06-03 Scott Dattalo <scott@dattalo.com>
	* gui/gui_main.cc: Added a call to g_main_iteration() to allow GTK
	events to get processed. (This replaces the GTKWAIT macro that was
	removed in the previous commit).

2005-06-02 Scott Dattalo <scott@dattalo.com>
	* gui/gui_src_asm.cc, gui/gui_main.cc: Removed GTKWAIT
	macros. Apparently on newer versions of GTK these macros block
	indefinitely. On really old versions of GTK (pre 2.0) these macros
	were necessary.

2005-05-26 J.R. Heisey <jrheisey@sourceforge.com>
	* src/breakpoints.cc,h, plat/win32/gpsim.def: added
	register assertions functionality. Can now assert the
	register value with !=, <=, >=, <, and > operators.

2005-06-01 Scott Dattalo <scott@dattalo.com>
	* src/os_dependent.cc: Printed an error message if
	a shared library fails to open.

2005-05-26 J.R. Heisey <jrheisey@sourceforge.com>
	* src/program_files.cc: Fixed crashing bug when no file
	types are able to open a program file.

2005-05-25 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.nsi, extras/lcd/makefile.mingw:
	added missing files to the WIN32 installation package in
	order to be able to compile the LCD modue; make LCD module
	mingw makefile a litle bit more flexible

2005-05-24 Scott Dattalo <scott@dattalo.com>
	* src/cod.cc, src/breakpoints.cc, src/trigger.cc,
	regression/assertions/assertions.asm: Added support
	for scripts embedded in .cod files.

2005-05-24 Scott Dattalo <scott@dattalo.com>
	* src/modules.h, src/modules.cc, src/processor.cc,
	src/breakpoints.cc, src/pic-processor.cc, src/hexutils.cc,
	gui/gui_src.cc, gui/gui_src_asm.cc, cli/scan.ll,
	src/cmd_manager.h, cli/cmd_dump.cc:

	-- renamed the enum's for the SIMULATION_MODE(s) (the
	enum 'INITIAL' collides with a macro in flex)
	-- added support for module scripts
	-- If a symbol begins with a period, then the scanner
	will automatically prepend the active processor name.
	(This is a short cut for accessing processor attributes).

2005-05-24 Borut Razem <borut.razem@siol.net>
	* doc/gpsimWin32.html, gpsim/gpsim.vcproj, gpsim/makefile.mingw:
	WIN32 with official release of gtk+extra-2.0.0

2005-05-22 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_break.cc, cli/cmd_break.h, cli/parse.yy, cli/scan.ll,
	src/breakpoints.cc, src/breakpoints.h, src/operator.cc,
	src/trigger.cc, src/trigger.h, src/value.cc:
	Added the capability of associating user defined messages with
	break points.
	Break point expressions (if present) are now displayed when the
	break points are displayed.
	* regression/assertions/Makefile,
	regression/assertions/assertions.asm: Use the coff.inc include
	file supplied with gputils and specifically the macros for
	assertions.

2005-05-21 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_break.h, cli/cmd_break.cc, cli/input.cc, cli/parse.yy,
	src/cod.cc, src/breakpoints.cc: Execution breakpoints were failing
	to propogate execute() if an attached expression evaluated false.
	Added support for gpasm style assertions.
	* cli/scan.ll: Shell command escape character ('!') was
	conflicting with the not operator.
	* regression/assertions/assertions.asm,
	regression/assertions/Makefile, regression/assertions/16f873.lkr:
	Added a regression test for gpasm assertions.

2005-05-20 Scott Dattalo <scott@dattalo.com>
	* cli/scan.ll, regression/run_regression.sh,
	regression/macro_test/macro_test.stc:  Macros can now be nested.

2005-05-20 Scott Dattalo <scott@dattalo.com>
	* gui/gui_profile.cc: ifdef'd out code that a) is seldom (never?)
	used and b) incompatible with the latest official release of
	gtkextra.

2005-05-19 Scott Dattalo <scott@dattalo.com>
	* src/ttoken.h, src/ttoken.cc, src/bytelog.cc, src/bytelog.h,
	src/pthread-wrap.h: Create a gpsim namespace and place the objects
	in these files in there.
	* cli/scan.ll: removed some printf debugging junk.

2005-05-19 Scott Dattalo <scott@dattalo.com>
	* cli/scan.ll, cli/cmd_macro.cc, cli/parse.yy, cli/input.cc:
	A recent change in string processing broke macros. Also, began
	adding code to support nested macros.
	* regression/macro_test/macro_test.asm,
	regression/macro_test/macro_test.stc: Added new regression test
	for macros.

2005-05-18 Scott Dattalo <scott@dattalo.com>
	* cli/scan.ll: Fixed end-of-line scan bug introduced on 5-16.

2005-05-16 J.R. Heisey <jrheisey@sourceforge.com>
	* src/os_dependent.cc: Added debug code to allow alternate
	directory paths for module libraries so I can specify debug
	build locations for shared libraries.
	* src/program_files.cc: Fixed bug caused by symbol table not
	being cleared when Program files are loaded.
	* src/modules.cc: Fixed bug when a module library failed to
	load it was still being added to the installed library list.
	* configure.ac: bumped build number to 0.21.5

2005-05-16 Scott Dattalo <scott@dattalo.com>
	* cli/input.cc, cli/scan.h, cli/scan.ll, cli/input.cc: command
	assertions where causing parse errors.

2005-05-14 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_processor.cc: The processor command wasn't working
	because of a typo in an if statement.
	* cli/parse.yy, cli/cmd_break.cc, cli/cmd_break.h: Added 'break
	#number' to allow inspection of an individual break point. Clean
	up some memory 	management.
	* src/breakpoints.cc: 'dump1()' wasn't checking to see if the
	break point number was valid.
	* src/os_dependent.cc: non-windows file extension comparisons were
	not working.
	* src/pic-processor.cc, src/symbol.h, src/symbol.cc, src/value.cc:
	val_symbols like the PIC program counter can now be parts of gpsim
	expressions.
	* src/cod.cc: hack - line number offset errof.
	* doc/gpsim.lyx: Updated the documentation.

2005-05-12 Scott Dattalo <scott@dattalo.com>
	* gui/gui_regwin.cc, gui/gui_src_opcode.cc, gui/gui_src_asm.cc:
	Removed calls to GTKWAIT because they sometimes block in the newer
	version (2.6.7) of GTK. Thanks to Micah Carrick for pin-pointing
	this one.

2005-05-11 Scott Dattalo <scott@dattalo.com>
	* src/sim_context.cc: The included file "direct.h" does not exist
	on FC3.

2005-05-10 J.R. Heisey <jrheisey@sourceforge.com>
	* cli/cmd_load.cc: Updated on line help for load command.
	* gui/gui_src_asm.cc: Removed a call to gtk_widget_destory()
	in SourcePage::Close() where it was causing a crash in Windows.
	* cli/scan.ll: Defined literal string values to be quoted. This
	was done so that quoted Windows paths in the load command to
	accommodate colons for drive designation and backslashes for
	folder delimiters.
	* gpsim/main.cc: Added the gpsim.exe startup folder to the
	module/library search path.
	* src/sim_context.cc, src/errors.h: Added an error message to CSimulationContext::
	LoadProgram().
	* cli/cmd_module.cc, src/modules.cc, src/modules.h,
	src/os_dependent.cc, gpsim/main.cc: Added code to not load
	a module library that is already loaded.

2005-05-06 J.R. Heisey <jrheisey@sourceforge.com>
	* gui/gui_regwin.cc:  Fixed crash that occurs when RAM register
	count is not a multiple of 16.
	* plat/win32/gpsim.def: Added new function reference.
	* src/processor.cc:  Fixed broken list command
	* src/sim_context.cc: Fixed broken register output on stepping
	that broken on previous check in. Test for open file failure.
	* src/program_files.h: Add new error code.

2005-05-05 J.R. Heisey <jrheisey@sourceforge.com>
	* cli/cmd_break.cc, cli/cmd_disasm.cc, cli/cmd_dump.cc,
	cli/cmd_frequency.cc, cli/cmd_list.cc, cli/cmd_load.cc,
	cli/cmd_load.h, cli/cmd_log.cc, cli/cmd_processor.cc,
	cli/cmd_reset.cc, cli/cmd_step.cc, cli/cmd_x.cc, cli/command.cc,
	cli/command.h, cli/input.cc, cli/input.h, cli/parse.yy,
	src/cod.cc, src/cod.h, src/hexutils.cc, src/Makefile.am,
	src/modules.h, src/os_dependent.cc, src/pic-processor.cc,
	src/pic-processor.h, src/processor.cc, src/processor.h,
	src/program_files.cc, src/program_files.h, src/sim_context.cc,
	src/sim_context.h, src/src.vcproj, src/symbol.cc, src/symbol.h,
	config_win32.h.in, configure.ac, plat/win32/gpsim.def,
	gui/gui_menu.cc, gui/gui_src_asm.cc, gui/gui_statusbar.cc,
	gpsim/Makefile.am:
	- Replaced the cli and gui references to hexfiles verses
	cod file with program files. Gpsim will now figure out
	the file type and load the file.
	- Both the gui and cli will recoginze command files by the stc
	file extension. All other files are assumed to be program files.
	- The c, h and s load options of the load command will be accepted
	for backwards compatibility of existing command files but are no
	longer needed.
	- The processor command is not optional. If the program file
	contains the information about the processor type, gpsim will
	allocate the processor type based on the program file information.
	Using the processor command overrides this behavior.

2005-05-01 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.def: MSVC sync

2005-04-29 Scott Dattalo <scott@dattalo.com>
	* HISTORY, README, INSTALL, configure.ac, gpsim.spec.in: Updates

	* extras/lcd/ChangeLog, Makefile.am, configure.in: bumped the Rev
	of the LCD module to 0.2.4

2005-04-29 Scott Dattalo <scott@dattalo.com>
	* src/breakpoints.cc: Register assertions were not halting
	simulation when assertion was true.

2005-04-26 Scott Dattalo <scott@dattalo.com>
	* cli/Makefile.am, examples/14bit/Makefile.am: Updated so that
	'make dist' would work again.
	* src/attributes.cc, src/init.cc: Moved attribute initialization
	from init.cc to attributes.cc
	* src/breakpoints.cc, src/symbol.cc, src/symbol.h, src/trigger.cc:
	Complex expressions are now fully supported. Updated the help info
	for the break command to reflect the new syntax (more work
	needed).

2005-04-26 Scott Dattalo <scott@dattalo.com>
	* src/breakpoints.cc, src/breakpoints.h, cli/parse.yy,
	cli/cmd_break.cc, cli/cmd_break.h: continuing with complex break
	expressions.

2005-04-25 Scott Dattalo <scott@dattalo.com>
	* src/trigger.h, src/trigger.cc, src/breakpoints.cc: Added complex
	expressions to the TriggerObject class. (not complete)

	* bitlog.cc, bitlog.h, bytelog.cc, bytelog.h, ttoken.cc, ttoken.h,
	pthread-wrap.h: moved these from the modules/ directory into the
	src/ directory.

2005-04-19 J.R. Heisey <jrheisey@sourceforge.com>
	* src/breakpoints.cc, src/processor.cc, src/processor.h:
	Fixed corruption when clearing a Breakpoint_Instruction object.
	The object was not removed properly from the chain of instruction
	objects in the pma.

2005-04-19 Scott Dattalo <scott@dattalo.com>
	* src/os_dependent.cc: Added 'errno.h' to the list of include
	files. (without this, os_dependent.cc wouldn't compile on
	FC3-64bit).

2005-04-19 Scott Dattalo <scott@dattalo.com>
	* src/symbol.cc, src/symbol.h: Fixed reference to symbol table
	that was preventing compilation on Linux.

2005-04-19 J.R. Heisey <jrheisey@sourceforge.com>
	*  gui/gui_src_asm.cc, gui/gui_statusbar.cc, gui/gui_statusbar.h:
	Modified the statusbar so that it can handle a switch from
	one processor to another.
	* src/sim_context.cc, src/symbol.cc,h: Fixed a crash on gpsim
	exit.
	* src/os_dependent.c: added test in load_library() to the first
	call to sLoad() to determine whether the a failure was due
	to the library file not found or some other error. This needs
	to be completed for the linux builds.

2005-04-18 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.cc: Stimulus_Node destructor now removes itself from
	the symbol table.

2005-04-17 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.h, src/stimuli.cc: Added methods to control the
	resistance and voltage of the IO_bi_directional_pu pullup resistor.

2005-04-16 Scott Dattalo <scott@dattalo.com>
	* src/symbol.cc: set methods for register symbol now initialize
	the "init" field in the register object.

2005-04-16 J.R. Heisey <jrheisey@sourceforge.com>
	* src/value.cc,h, src/symbol.cc,h, src/processor.cc,h,
	src/pic-processor.cc,h, makefile.mingw, Makefile.am,
	cli/input.cc, cli/init.cc, gui/gui_symbols.cc, gui/gui_stack.cc,
	gui/gui_src_asm.cc, gui/gui_profile.cc, src/gpsim_time.cc,
	plat/win32/gpsim.def, src/cod.cc, cli/cmd_processor.cc,
	added src/sim_context.cc.h: Restructured classes in preparation
	for allowing a simulation context to be reset for a new processor
	with out having to close the program and with out memory leaks.
	The new class CSimulationContext, implemented as a singleton for
	now, owns a CProcessorList. The singelton class
	ProcessorContructorList is used to create processor objects.
	Eventually CSimulationContext may own Breakpoints, Symbol_Table
	and the active_cpu objects. For now. there are accessor functions
	to get to the global objects. CSimulationContext.set_processor()
	will check for a matching processor in the processor list before
	allocating a new processor.
	Processor related classes now delete the objects that they own
	on destruction. May not be conprehensive. set_processor() currently
	deletes a matching processor object rather than reinitializing it
	for a new simulation session.

2005-04-15 Scott Dattalo <scott@dattalo.com>
	* cli/command.h, cli/input.cc, cli/parse.yy, cli/scan.ll,
	gpsim/main.cc: Finished support for reentrant parsing.
	* cli/cmd_disasm.cc: Cleaned up a buglet in printing.
	* src/attributes.cc, src/attributes.h, src/pic-processor.cc,
	src/processor.cc, src/processor.h: Added an attribute that
	controls the behavior of simulator when a reset is encountered.

2005-04-15 Scott Dattalo <scott@dattalo.com>
	* src/cod.cc, cli/cmd_run.cc, cli/cmd_run.h, cli/input.cc,
	cli/input.h, cli/parse.yy, cli/scan.ll:
	Added initial support for .COD file assertions.
	  -- Parser is now reentrant
	  -- gpsim's CLI interface is now a registered interface
	     that can be referenced and accessed by the simulation
	     engine.
	* src/ioports.cc: experimental tinkering

2005-04-14 Scott Dattalo <scott@dattalo.com>
	* build.xml: configure was not getting invoked.

2005-04-14 Scott Dattalo <scott@dattalo.com>
	* build.xml: autoconf was not getting invoked...

2005-04-13 Scott Dattalo <scott@dattalo.com>
	* build.xml: An XML script for an experimental regression tool
	(based on the open source projects "ant" and "CruiseControl").

2005-04-09 Borut Razem <borut.razem@siol.net>
	* cli/makefile.mingw, src/makefile.mingw: MINGW sync

2005-04-08 J.R. Heisey <jrheisey@sourceforge.com>
	* src/breakpoints.cc, src/cmd_manager.cc,h, gpsim/main.cc,
	src/processor.cc,h, cli/ui_gpsim.cc,h, src/registers.cc,
	cli.vcproj, gpsim.vcproj, src.vcproj: Created a IUserInterface
	and CGpsimUserInterface as the implementation with functions to
	write predefined parameterized strings to the console (or in the
	future a GUI popup).
	Modules call the C function GetUserInterface() to retrieve an
	instance of CGpsimUserInterface as a IUserInterface.
	Using IUserInterface functions is the prefered way of writing error
	and notification messages to the gpsim console from other modules.

2005-04-08 Scott Dattalo <scott@dattalo.com>
	* cli/parse.yy, cli/cmd_break.h: Added support for a break command
	like:
	    break r|w reg(N)
	Where N is an integer and 'reg' is the new reg operator.

2005-04-08 Scott Dattalo <scott@dattalo.com>
	* cli/parse.yy, cli/scan.ll: Added a "reg()" operator that can cast
	integers into registers (although this is not fully implemented
	yet).
	A single quote before an identifier now acts as an 'escape'
	character. This allows user defined strings to collide with gpsim
	built in strings. (e.g. If a user has a variable named help, its
	contents can be examined by typing 'help at the command line).

2005-04-07 J.R. Heisey <jrheisey@sourceforge.com>
	src/breakpoints.cc: Fixed a memory leak by properly removing
	chained BreakpointRegister objects from the Register chain when
	clearing a break object. When the chain is properly maintained
	the object may be deleted.

2005-04-07 J.R. Heisey <jrheisey@sourceforge.com>
	* cli/scan.ll, cli/parse.yy, cli/cmd_break.cc,h,
	src/processor.cc,h, src/pic-processor.cc, operator.cc,h,
	src/breakpoints.cc: Changed the break command syntax.
	Added code to support the syntax.

2005-04-07 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_manager.h, cli/cmd_manager.cc, cli/cmd_gpsim.h:
	moved from cli/ to src/
	* src/processor.cc, src/Makefile.am, src/interface.cc,
	src/processor.cc, gpsim/main.cc, cli/Makefile.am,
	cli/cmd_manager.cc, cli/cmd_module.cc, cli/cmd_shell.cc:
	Updated these files to use the newly relocated .h files. The reason
	for doing this is to fix a src/ dependency on cli/ files. When
	src/ depends on cli/ then any module that links against the gpsim
	library must also link against the cli library.
	* src/registers.cc: added a Bit class (currently not used though)
	* src/symbol.cc: attribute symbols that wrap other symbols now change
	the name of the wrapped symbol. This allows heirarchical names
	such as processor_name.attribute to appear in the symbol table.

2005-04-06 J.R. Heisey <jrheisey@sourceforge.com>
	* src/processor.cc.h: Two new break message functions.

2005-04-05 J.R. Heisey <jrheisey@sourceforge.com>
	* src/value.h, src/registers.cc,h, src/processor.cc.h,
	src/preakpoints.cc,h, plat/win32/gpsim.def: Implemented
	classes and functions for displaying the register address
	and possible value for break on read and break on write.

2005-04-05 J.R. Heisey <jrheisey@sourceforge.com>
	* gpsim/main.cc, src/interface.cc, src/gpsim_interface.h,
	cli/cmd_manager.h: Added code to support for an external module to
	access the global ISimConsole object from the Interface class.

2005-04-04 J.R. Heisey <jrheisey@sourceforge.com>
	* src/processor.cc,h: Added the function Processor::IsAddressInRange().
	Use IsAddressInRange() in ProgramMemoryAccess::get_src_line() and
	ProgramMemoryAccess::operator [](unsigned int address)

2005-04-02 Scott Dattalo <scott@dattalo.com>
	* src/processor.cpp: Reverted the change J.R. made on 2005-03-31
	because it breaks the gui for the 18F family of PICs. We'll need
	to come up with another way of solving the initial PC value
	problem.

2005-03-31 J.R. Heisey <jrheisey@sourceforge.com>
	* src/processor.cpp: Changed call ProgramCounter->get_PC() to
	ProgramCounter->get_value() to fix a problem where the initial
	position of the PC in the source was not getting set properly.
	Return value is used for indexing into source code line.
	Mostly used by the UI so should not affect behavior.

2005-03-30 J.R. Heisey <jrheisey@sourceforge.com>
	* cli/cmd_dump.cc: Changed ram dump command to handle ram sizes
	greater than one byte.
	* cli/cmd_x.cc: Removed call to dump.dump(DUMP_SFRS) since previous
	call to dump.dump(DUMP_RAM) already dump thes sfrs too.ram halt.
	* Cleaned up a couple of GUI error messages. (invalid window handle,
	invalid value strings)

2005-03-24 J.R. Heisey <jrheisey@sourceforge.com>
	* src/breakpoints.cc, src/processor.cc, h, cli/cmd_clear.cc:
	Fixed crash in Breakpoints::clear() that I reintroduced in my last checkin.
	Also Fixed the original memory leak by properly removing chained
	Breakpoint_Instruction objects from the instruction chain when clearing a
	break object. When the chain is properly maintained the object may be
	deleted. Perhaps this should be a temporary fix until a base class
	for Breakpoint_Instruction all have a replaced member.

2005-03-23 Scott Dattalo <scott@dattalo.com>
	* gui/gui_src_asm.cc: changed the comment text color to 'dim gray'

2005-03-23 Scott Dattalo <scott@dattalo.com>
	* src/value.cc: Fixed write to a null pointer in String::get(char
	*buf, int len).
	* src/symbol.cc: Fixed infinite loop in
	char *register_symbol::name (char *buf, int len).
	* regression/ccp/ccp.asm: added more features to the ccp
	regression test.

2005-03-22 J.R. Heisey <jrheisey@sourceforge.com>
	* gui/gui_watch.cc: Fixed problem with register values > 127 causing pango runtime warnings

2005-03-21 J.R. Heisey <jrheisey@sourceforge.com>
	* src/breakpoints.cc, src/processor.h: created a notification
	to Processor when breakpoints are set or cleared. Cleaned up
	code in breakpoints.cc.

2005-03-23 Scott Dattalo <scott@dattalo.com>
	* src/16bit-instructions.cc: The NEGF instruction for the 18f
	family was erroneously writing the negated result to W.
	* regression/instructions_16bit/instructions_16bit.asm: added a
	regression test for the NEGF instruction.

2005-03-21 J.R. Heisey <jrheisey@sourceforge.com>
	* src/processor.cc: Copy a null string to input parameter
	Processor::get(char *cP, int len) because not value is
	associate with a Processor object. Fixes trace errors from
	pango when the symbol window is scrolled to some symbol objects.
	* src/value.cc: Copy a null string to input parameter
	String::get(char *buf, int len) when not value string is
	allocated. Fixes trace errors from pango when symbol window
	is scrolled to some symbol objects.

2005-03-18 J.R. Heisey <jrheisey@sourceforge.com>
	* cli/cmd_load.cc/h, src/cod.cc/h, cli/input.cc, cli/parse.yy:
	added error checking for opening cod, hex and stc files.
	Particularily when opened from the GUI.

2005-03-17 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.cc: tweaking of I/O thresholds.

2005-03-16 Scott Dattalo <scott@dattalo.com>
	* cli/scan.ll, src/stimuli.h, src/stimuli.cc, src/symbol.cc,
	src/symbol.h: Added/enhanced methods for searching, adding, and
	removing symbols and stimuli.

2005-03-14 J.R. Heisey <jrheisey@sourceforge.com>
	* src/modules.h, modules.cc, os_dependent.cc: Elimaticated
	undesired error message on failure to load a function of a
	module.
	Simplified Module_Library() constructor to use os independent
	api call get_library_export()

2005-03-14 Scott Dattalo <scott@dattalo.com>
	* plat/win32/gpsim.def: MSVC sync.
	* modules/modules.vcproj: Use new pthread library.
	* gui/gui_register.h, gui/gui_regwin.cc: pass registerValue by
	value in getValueAsString() method.

2005-03-03 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.def: MSVC sync

2005-03-10 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.cc: Added an 'X' state to getBitChar method
	of the IO_open_collector class.

2005-03-09 Borut Razem <borut.razem@siol.net>
	* modules/makefile.mingw: pthreads upgrade

2005-03-08 Scott Dattalo <scott@dattalo.com>
	* src/value.cc, gui/gui_profile.cc, gui/gui_statusbar.cc,
	gui/gui_trace.cc: Corrected temporary hack regarding PRINTF_INT64_MODIFIER

2005-03-08 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.nsi: removed examples\14bit\*.inc
	* cli/cmd_manager.h: added newline at the end of file
	* doc/gpsimWin32.html: atk upgraded to 1.8.0

2005-03-08 Scott Dattalo <scott@dattalo.com>
	* regression/ccp/ccp.asm: improvements to ccp regression test
	* gui/gui_profile.cc, gui/gui_trace.cc, gui/gui_statusbar.cc,
	src/value.cc: Temporarily removed windows-specific macro.
	* src/stimulus.cc, src/stimuli.h: Cleaned up asynchronous stimuli
	* src/registers.h, src/ssp.cc, src/ioports.cc, src/14bit-tmrs.cc:
	Made the default register class access functions all go through
	one function to obtain a register's value.

2005-02-26 Scott Dattalo <scott@dattalo.com>
	* src/processor.h, src/trace.h, src/breakpoints.h, src/symbol.h,
	src/gpsim_interface.h, src/gpsim_time.h:
	The external references demarcated by 'IN_MODULE' were not getting
	resolved in FC3. Since these were introduced to resolve a linking
	problem with WIN32 DLL's, I made the demarcation dependent on only
	Windows.

2005-02-25 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.h, src/stimuli.cc: Added methods to the IOPIN class
	to differentiate between a pin driving a node and one being driven
	by a node.
	* src/14bit-tmrs.cc, src/i2c-ee.cc, src/packages.cc, src/ssp.cc,
	src/stimuli.cc, src/stimuli.h, src/uart.cc, extras/lcd/lcd.cc,
	gui/gui_breadboard.cc, modules/logic.cc, modules/logic.h,
	modules/usart.cc, modules/video.cc, modules/video.h: Propogate
	IOPIN change to all consumers.

2005-02-24 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.h, src/stimuli.cc: Added impedance thresholds
	to differentiate strong, weak, and floating drivers.

2005-02-16 Scott Dattalo <scott@dattalo.com>
	* src/ioports.cc: experiments in ioport redesign.

2005-02-16 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.h, src/stimuli.cc: Added 'getBitChar()' method to
	the open collector stimulus class.

2005-02-15 Scott Dattalo <scott@dattalo.com>
	* src/ioports.cc, src/ioports.h: Added a 'getIO' method to the
	IOPIN class that will allow an individual I/O pin in a port to be
	accessed.
	* src/stimuli.h, src/stimuli.cc: Add more state information to the
	snode class. Also, added the 'getBitChar()' method that will
	return the state of the stimulus in the form of an ASCII character
	(e.g. 0,1,Z,W).

2005-02-11 Scott Dattalo <scott@dattalo.com>
	* src/os_dependent.cc: Libraries stored in system directories were
	getting ignored.

2005-02-09 Scott Dattalo <scott@dattalo.com>
	* src/Makefile.am: Newly added src file 'os_dependent.cc' was not
	part of the Makefile
	* cli/input.cc, src/os_dependent.cc: abstracted some os dependent
	changes that were recently added

2005-02-01 Scott Dattalo <scott@dattalo.com>
	* src/processor.h, src/processor.cc, src/trace.cc: Added 'Debug()'
	method to processor class and call it whenever a register
	assertion occur.s

2005-01-30 Borut Razem <borut.razem@siol.net>
	* config_win32.h.in, configure_win32.awk: extract version, package and
	  bugreport values from configure.ac

2005-01-26 Scott Dattalo <scott@dattalo.com>
	* configure.ac: repositioned the call to the m4 macro wi_READLINE_LIB
	so that it would run properly.

2005-01-26 Scott Dattalo <scott@dattalo.com>
	* plat/win32/gpsim.def: added more external cross references.
	* module/modules.vcproj: changed from pthreadVC1.lib to
	pthreadVC.lib.

2005-01-23 Scott Dattalo <scott@dattalo.com>
	* configure.ac: Craig Franklin updated gpsim's configure files. It
	turns out there was a tiny bug preventing things to build a
	*second* time (the first time would work fine)
	* src/gpsim_time.h, src/gpsim_time.cc, src/init.cc: The newly
	added and globally instantiated StopWatch class' constructor was
	making calls to the globally instantiated (but not necessarily
	constructed) Symbol_Table class. Now, StopWatch::init() will make
	the calls to the symbol table.

2005-01-21 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.def, src/src.vcproj: MSVC sync
	* doc/gpsimWin32.html: gpsim works with flex 2.4.31

2005-01-20 Scott Dattalo <scott@dattalo.com>
	* src/breakpoints.cc: Trigger actions were not printing
	execution breakpoint messages.
	* src/registers.h, src/registers.cc: Added a skip_start function to
	the program counter.

2005-01-19 Scott Dattalo <scott@dattalo.com>
	* src/registers.cc, src/registers.h, src/gpsim_object.cc,
	  src/gpsim_object.h, src/symbol.cc, src/symbol.h,
	  src/value.cc, src/value.h: Added the 'toBitStr' method
	to gpsim_object and propopogated the change through the
	derived classes. Also, the register class now calls get() to
	obtain the value printed with toString and toBitStr instead
	of directly using its value object.

2005-01-17 Scott Dattalo <scott@dattalo.com>
	* src/gpsim_time.h, src/gpsim_time.cc: Finished the StopWatch
	class.
	* src/value.cc, src/value.h, src/attributes.cc, src/attributes.h:
	Added attribute breakpoints. For attributes that can be associated
	with breakpoints, you can now write 'break attribute' to set a
	breakpoint on that attribute.
	* cli/Makefile.am, cli/cmd_break.cc, cli/cmd_break.h,
	cli/cmd_help.cc, cli/command.cc, cli/parse.yy: The 'stopwatch'
	command is now handled by attributes. Added the following
	attributes:
	stopwatch, stopwatch.enable, stopwatch.direction,
	stopwatch.rollover.
	The 'stopwatch' attribute supports breakpoints, so the 'break
	stopwatch'  command will break whenever the stopwatch rolls over.

2005-01-15 Scott Dattalo <scott@dattalo.com>
	* src/attributes.cc, src/attributes.h: New files to support gpsim
	attributes.
	* src/Makefile.am, src/makefile.mingw: added the new files to the
	make files.

2005-01-14 Scott Dattalo <scott@dattalo.com>
	* gpsim/main.cc, gui/gui_main.cc: The gtk main loop is now started
	even if the command line option --cli is specified. This way, the
	GIOChannels will still operate.

2005-01-13 Scott Dattalo <scott@dattalo.com>
	* cli/sockect.cc, src/value.cc: Added support for 'Socket Sinks'
	and 'Socket Sources'. These essentially are two ways in which a
	client can choose to communicate with gpsim.

2005-01-10 Scott Dattalo <scott@dattalo.com>
	* cli/sockect.cc, src/protocol.cc, src/protocol.h,
	src/symbol.cc, src/symbol.h, src/value.cc,src/value.h:

	example illustrating socket callbacks.
	* gui/gui_main.cc: removed a printf debug statement.

2005-01-09 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.def: MSVC sync
	* doc/gpsimWin32.html: dependedncy on gawk, ...
	* cli/cli.vcproj, cli/scan.ll: make it work with flex 2.4.31
	* plat/win32/gpsim.nsi, modules/makefile.mingw, modules/modules.vcproj:
	  pthreads 2005-01-03
	* gui/gui_menu.cc: use utf-8 encoded LATIN SMALL LETTER Z WITH CARON
	  instead LATIN SMALL LETTER Z.

2005-01-07 Scott Dattalo <scott@dattalo.com>
	* src/16bit-processors.cc: stop gap hack - added registers
	to hold the places of the analog SFR's
	* cli/socket.cc, src/protocol.h, src/value.cc, src/value.h:
	More socket improvements.

2005-01-05 Scott Dattalo <scott@dattalo.com>
	* src/breakpoints.cc, src/gpsim_classes.h, src/gpsim_interface.h,
	src/interface.cc, src/modules.cc, src/modules.h,
	src/pic-processor.cc, src/protocol.cc, src/protocol.h,
	cli/command.cc, cli/socket.cc:
	Enhancements to support the socket interface. Added a run command
	and a reset command and made them invocable via the interface class.

2005-01-02 Scott Dattalo <scott@dattalo.com>
	* gui/gui_main.cc, cli/input.cc, src/interface.cc: Added function
	'gUseThreads()' and use it to run-time select the usage of threads.

2005-01-02 Borut Razem <borut.razem@siol.net>
	* gui/gui_break.cc, gui/dialog.cc, gui/gui_init.cc, gui/gui_menu.cc,
	  gui/gui_processor.cc, gui/gui_src.cc, gui/gui_src_asm.cc
	  gui/gui_src_opcode.cc: removed unneeded include gtkcombobox.h
	* gui/gui_breadboard.cc: fixed compiler warnings
	* cli/Makefile.am, gui/Makefile.am: added AM_ preffix to CFLAGS,
	  CXXFLAGS, CPPFLAGS and YFLAGS
	* doc/gpsimWin32.html: gtk+ version 2.4.14, XHTML 1.0 Transitional compliant,
	  gtk+extra-2-1.1.0-20050102
	* doc/gpsim_cvs.html: changed first build instructions

2004-12-17 Scott Dattalo <scott@dattalo.com>
	* gui/gui_main.cc, src/interface.cc, cli/socket.cc: removed
	dependencies on GTK 2.0.

2004-12-19 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.nsi: added examples/scripts/client_interface.h
	  to installation
	* mingw/makefile.mingw, gpsim/gpsim.vcproj: added gthread-2.0.lib
	* src/src.vcproj: removed plat\win32\glist.cpp from project; CLI
	  mode now requires linking with full glib library; added src/trigger.cc
	  and src/trigger.h to the project
	* modules/modules.vcproj: pthreads to the project
	* gpsim.sln: removed building of modules in CLI configuration

2004-12-17 Scott Dattalo <scott@dattalo.com>

	test threading.

2004-12-16 Scott Dattalo <scott@dattalo.com>
	* gui/gui_main.cc, gui/gui_menu.cc: Use the interface instead of
	the cpu pointer to initiate simulation.
	* src/Makefile.am, src/trigger.cc, src/trigger.h,
	src/breakpoints.cc, src/breakpoints.h: Split the
	trigger classes away from the breakpoint classes.
	* src/gpsim_interface.h, src/init.cc, src/interface.cc,
	src/pic-processor.cc, src/protocol.cc, src/protocol.h,
	src/trace.h, cli/cmd_run.cc, cli/cmd_set.cc, cli/cmd_trace.cc,
	cli/input.cc, cli/socket.cc:
	Attempted (but failed) to add a feature that would allow a socket
	interface to send data to the simulator while a simulation is
	running. It turns out that the giochannel stuff used to control
	the socket runs in the gui event loop. The only time the socket is
	handled is whenever the loop can run. However, since gpsim is a
	single threaded application (the gui does spawn its own private
	thread), the gui event loop only runs whenever the simulation
	gives it cpu time. Thus it's not possible for a socket to update
	the simulation except when the gui is being refreshed!
	* examples/scripts/client.cc, examples/scripts/gensquares.asm,
	examples/scripts/makefile, examples/scripts/client2.cc,
	examples/scripts/client_interface.cc,
	examples/scripts/client_interface.h:
	Added a class to encapsulate the gpsim client socket
	interface. Added another example to test socket updates while the
	simulation is running.

2004-12-16 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.def: MSVC sync
	* src/14bit-registers.h: declare void
	  Status_register::put(unsigned int new_value) as virtual, not inline
	* gui/gui_src_opcode.cc: removed definition of unused variable pm_size
	  in method SourceBrowserOpcode_Window::NewProcessor()
	* extras/lcd/makefile.mingw: added
	* plat/win32/gpsim.nsi: added additional files from examples\scripts to
	  the package
	* cli/input.cc: function have_line() is needed also in non GUI mode
	* gui/profile.cc, gui/gui_statusbar.cc, gui/gui_stopwatch.cc,
	  gui/gui_trace.cc, src/14bit-tmrs.cc, src/16bit-registers.cc,
	  src/eeprom.cc, src/i2c-ee.cc, src/interface.cc, src/interface.h,
	  src/ioports.cc, src/p16x7x.cc, src/pic-processor.cc,
	  src/pic-registers.cc, src/ssp.cc, src/stimuli.cc, src/tmr0.cc,
	  src/uart.cc: replace direct access to cycles with a getter
	  function get_cycles()

2004-12-15 Scott Dattalo <scott@dattalo.com>
	* src/init.cc, src/gpsim_time.cc:
	Delayed creation of the cycle counter attribute. It turns out that
	this attribute was created in the Cycle_Counter constructor which
	is called by the globally instantiated 'cycles' object. On
	Windows, this call happened before the symbol table was
	inititialized .

2004-12-14 Scott Dattalo <scott@dattalo.com>
	* src/init.cc: added new function for initialization. Also added
	new attribute 'sim.verbosity' that will control the simulator's
	verbosity. Note, this duplicates the behavior of the global
	variable 'verbose'. However, the goal is to phase out the global
	variable.
	* cli/cmd_run.cc: the run command now examines the new verbosity
	attribute.
	* src/pic-processor.cc, src/pic-processor.h, src/processor.cc,
	src/processor.h: the run member function now takes a parameter
	that controls whether or text will be printed.
	* cli/socket.cc:
	* src/interface.h: added extern def for new init function.
	* gpsim/main.cc: call new initialization function
	* src/breakpoints.cc: removed superfluous carriage return print.
	* examples/scripts/README, examples/scripts/client.cc,
	examples/scripts/makefile:  added  new files to illustrate
	scripting.
	* examples/scripts/gensquares.asm: minor tweak to simplify example
	regression test.

2004-12-14 Scott Dattalo <scott@dattalo.com>
	* cli/scan.ll, cli/socket.cc, src/protocol.cc, src/protocol.h,
	src/value.cc: Fixed compilation issues with FC3 on an Athlon 64.

2004-12-11 Borut Razem <borut.razem@siol.net>
	* src/makefile.mingw, src/src.vcproj: added protocol.cc and protocol.h
	* plat/win32/gpsim.def: MSVC sync

2004-12-10 Scott Dattalo <scott@dattalo.com>
	* src/gpsim_time.cc: Added a "cycles" attribute for interfacing
	with the cycle counter class.
	* src/protocol.cc, src/protocol.h, src/symbol.cc, src/symbol.h,
	src/value.cc, src/value.h, cli/socket.cc:
	More improvements to the protocol stuff.

2004-12-09 Scott Dattalo <scott@dattalo.com>
	* src/protocol.h, src/protocol.cc, src/Makefile.am: New files to
	support a communication protocol for gpsim.
	* cli/socket.cc: moved much of the protocol related stuff to the
	new files.
	* src/value.h, src/value.cc, src/symbol.h, src/symbol.cc: Symbols
	and Values can now be assigned by Packets.
	* src/12bit-instructions.h, src/12bit-processors.h,
	src/14bit-instructions.h, src/14bit-processors.h,
	src/14bit-tmrs.h, src/16bit-processors.h, src/16bit-tmrs.h,
	src/breakpoints.h, src/p12x.h, src/p16f62x.h, src/p16x5x.h,
	src/p16x6x.h, src/p16x8x.h, src/pic-instructions.h,
	src/pic-processor.h, src/processor.h, src/trace.h, src/xref.h:
	fixed typo in GPL disclaimer.

2004-12-07 Scott Dattalo <scott@dattalo.com>
	* cli/socket.cc: More socket clean up
	* src/modules.cc, src/modules.h, src/processor.cc,
	src/processor.h, src/symbol.cc, src/symbol.h: Removed deprecated
	code for setting/getting attributes. Added a new member function
	to the module_symbol that allows a character string to assign
	values to a module (this doesn't do anything yet).

	* modules/resistor.cc, modules/resistor.h, modules/usart.cc,
	modules/usart.h: removed deprecated set_attribute member function.

2004-12-06 Scott Dattalo <scott@dattalo.com>
	* cli/socket.cc: Experimenting with binary data. Cleaned up socket
	link creation. Added a generic symbol read/write socket command.

2004-12-06 Scott Dattalo <scott@dattalo.com>
	* cli/socket.cc: Wrap gtk2.x calls with #defines

2004-12-02 Scott Dattalo <scott@dattalo.com>
	* cli/socket.cc: More additions to SocketLinks. It's now possible
	to tie a socket to a gpsim attribute. This allows an external
	application to directly control gpsim's behavior.

2004-12-02 Scott Dattalo <scott@dattalo.com>
	* src/pic-processor.h, src/pic-processor.cc, src/p16f87x.h,
	src/p16f87x.cc: Added the PIC 16f876

2004-12-01 Scott Dattalo <scott@dattalo.com>
	* cli/socket.cc: Fixed the socket interface for issues related
	to gtk 2.x. Began adding the SockeLink class. This class will
	sit on top of the socket interface and will hide it from the
	clients. The clients will be able to open SocketLinks and connect
	directly to gpsim internal objects.

2004-12-01 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.def: MSVC sync

2004-11-30 Scott Dattalo <scott@dattalo.com>
	* gpsim/gpsim.vcproj: Removed references to files resource.h and
	gpsim.rc.

2004-11-30 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_break.cc, cli/cmd_break.h, cli/cmd_help.cc, cli/cmd_help.h,
	cli/cmd_load.cc, cli/cmd_load.h, cli/cmd_log.cc, cli/cmd_log.h,
	cli/cmd_macro.cc,, cli/cmd_macro.h, cli/cmd_module.cc, cli/cmd_module.h,
	cli/cmd_processor.cc,, cli/cmd_processor.h, cli/cmd_symbol.cc,
	cli/cmd_symbol.h, cli/command.cc, cli/misc.h, cli/parse.yy, cli/scan.ll:
	Changed the parser token STRING to LITERAL_STRING_T. The reason for
	this is to allow string type attributes to be treated like numeric
	attributes.
	* src/pic-processor.cc, src/pic-processor.h, src/processor.cc,
	src/processor.h, src/symbol.cc, src/symbol.h, src/value.cc,
	src/value.h:
	- Enhanced the 'String' class so that 1) it uses char * instead
	of STL string (yes this IS an enhancement) 2) the set() and get()
	methods can read and write to the String class.
	- Changed many instances of 'char *' to 'const char *'.

2004-11-29 Scott Dattalo <scott@dattalo.com>
	* src/pic-processor.cc, src/processor.cc, src/processor.h,
	src/trace.cc, src/value.cc, src/value.h: Change Integer,
	Boolean, and Float classes back to hold values of native types
	(as opposed to holding pointers to the native types).
	* modules/video.cc: changed reference to cpu->frequency to
	cpu->set_frequency

2004-11-29 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_stimulus.cc: register stim were not getting started.
	* regression/register_stim/register_stim.[asm|stc],
	regression/run_regression.sh:
	Added a regression test for register stimuli.

2004-11-29 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.h, src/stimuli.cc, src/value.cc, src/value.h: Redesigned
	the 'asynchronous_stimulus' to be a 'ValueStimulus'.
	Added a new stimulus type: AttributeStimulus. An attribute stimulus
	is a stimulus that can be tied directly to some attribute. For example,
	a register symbol is a type of attribute. So an attribute stimulus
	can be tied to a register symbol to create a 'register stimulus'.
	* cli/cmd_stimulus.cc, cli/command.cc, cli/parse.yy: Added support
	for attribute stimuli.

2004-11-28 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.def: MSVC sync

2004-11-24 Scott Dattalo <scott@dattalo.com>
	* src/processor.cc: operator[] for FileContext was not checking
	negative indices.

2004-11-24 Scott Dattalo <scott@dattalo.com>
	* cli/input.cc: yet another attempt to fix tab completion.
	* modules/binary_indicator.cc, modules/binary_indicator.h
	modules/bitlog.h, modules/led.h, modules/logic.cc, modules/logic.h,
	modules/paraface.h, modules/resistor.cc, modules/video.cc,
	modules/video.h: Changed IO_input to IOPIN for all pins. This
	is an attempt to remove a warning message regarding IO_input that
	is generated while building under CygWin.
	* modules/makefile.mingw, plat/win32/gpsim.nsi: Renamed modules.dll
	to a slightly more descriptive gpsim_modules.dll
	* src/i2c-ee.cc, src/p12.cc, src/p16f62x.cc, src/p17c75x.cc,
	src/stimuli.h: exchanged references to IO_input to IOPIN.

2004-11-23 Scott Dattalo <scott@dattalo.com>
	* plat/win32/gpsim.def, modules/modules.vcproj: MSVC sync
	* modules/*.cc: removed (char *) casts in calls to new_name()
	* gpsim/main.cc: removed some unnecessary includes.
	* gpsim/gpsim.vcproj: MSVC sync
	* cli/input.cc: removed some debug stuff
	* cli/cmd_log.cc: removed unreferenced variable.

2004-11-23 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.def, modules/modules.vcproj: MSVC sync

2004-11-23 Scott Dattalo <scott@dattalo.com>
	* cli/input.cc: The tab completion fix for window's now causes
	a crash on Linux. Sigh. Now both oses are supported (without crashes)

2004-11-23 Scott Dattalo <scott@dattalo.com>
	* cli/input.cc: Fixed tab completion related window's crash
	* gui/gui_symbols.cc: Windows doesn't support strndup()

2004-11-22 Scott Dattalo <scott@dattalo.com>
	* cli/input.cc: buffer overflow in command_generator().
	* src/ioports.cc, src/pic-registers.cc, src/registers.cc,
	src/stimuli.cc: valgrind check - unitialized memory.
	* src/value.h, src/value.cc, src/interface.h, src/symbol.cc,
	src/symbol.h, gui/gui_profile.cc, gui/gui_regwin.cc, gui/gui_regwin.h,
	gui/gui_src.cc, gui/gui_src.h, gui/gui_src_asm.cc, gui/gui_stack.cc,
	gui/gui_symbols.cc, gui/gui_watch.cc, gui/gui_watch.h:
	The gui was accessing the symbol table improperly. A new
	Symbol_Table_Iterator class was created to abstract accesses to the
	symbol table. In addition, get() and set() methods were added to
	the symbol classes that will allow reading/writing symbol values
	using strings.

2004-11-19 Scott Dattalo <scott@dattalo.com>
	* gui/gui_breadboard.cc, gui/gui_regwin.cc, cli/parse.yy: valgrind
	check - fixed some uninitialized memory.

2004-11-19 Scott Dattalo <scott@dattalo.com>
	* gui/gui_breadboard.cc: Don't let modules open a closed breadboard
	window.

2004-11-18 Scott Dattalo <scott@dattalo.com>
	* cli/input.cc: disallow TAB characters under windows since it
	causes a crash most of the time.
	* modules/bitlog.cc, modules/bytelog.cc, modules/ttoken.cc,
	modules/makefile.mingw: These were not getting built under windows.
	* plat/win32/gpsim.nsi: added pthreadVC.dll to gpsim's windows binary
	distribution.
	* doc/gpsimWin32.html: Updated documentation for pthreads.

2004-11-17 Scott Dattalo <scott@dattalo.com>
	* src/processor.cc, src/value.cc, src/value.h: made Integer,Float
	and Boolean values get() and set() their values through just one
	member function. This allows derived attributes to trap reads and
	writes to the values.

2004-11-16 Scott Dattalo <scott@dattalo.com>
	* src/value.h, src/value.cc, src/processor.h, src/processor.cc,
	src/pic-processor.cc, src/symbol.h, src/symbol.cc: Added 3 new
	attributes: SafeMode, WarnMode, and UnknownMode to control the
	simulator's behavior under certain simulation conditions. Attribute
	handling has also been enhanced.
	* cli/parse.yy, cli/cmd_help.cc, cli/cmd_help.h: Help command
	will display information about attributes.

2004-11-15 Scott Dattalo <scott@dattalo.com>
	* src/ioports.h, src/ioports.cc, src/16bit-registers.cc: Beginning
	to redesign I/O ports.

2004-11-14 Scott Dattalo <scott@dattalo.com>
	* src/i2c-ee.cc, src/ioports.cc, src/ioports.h, src/stimuli.cc,
	src/uart.cc: The usart has bitrotted. The relatively recent I/O pin
	changes broke this and probably other peripherals too.
	* modules/Makefile.am: added new files.
	* modules/pthread-wrap.h, modules/ttoken.cc, modules/ttoken.h:
	The token class provides co-routine support for modules.
	* modules/bitlog.cc, modules/bitlog.h, modules/bytelog.cc,
	modules/bytelog.h: Bit and Byte event loggers. bitlog was originally
	part of the uart module.
	* modules/usart.cc, modules/usart.h: removed the bit logger class and
	am now making an attempt to resurrect this code.

2004-11-10 Scott Dattalo <scott@dattalo.com>
	* cmd/cmd_break.cc: updated the help description for 'break'
	* src/operator.cc, src/symbol.h, src/symbol.cc: Allow registers
	to be type-cast into integers.

2004-11-10 Scott Dattalo <scott@dattalo.com>
	* gui/gui_breadboard.cc:
	* src/breakpoints.cc, src/gpsim_object.cc, src/gpsim_object.h,
	src/modules.cc, src/processor.cc, src/registers.cc, src/registers.h,
	src/symbol.cc, src/symbol.h:
	- More attribute enhancements
	- added a module load capability that uses attributes.

	gui/gui_stack.cc, gui/gui_statusbar.cc, gui/gui_symbols.cc:
	- Removed debugging printfs.
	- Changed attribute handling.
	* src/cod.cc, src/expr.cc, src/expr.h, src/gpsim_object.cc,
	src/modules.cc, src/p16x8x.cc, src/pic-processor.cc, src/processor.cc
	src/stimuli.cc, src/stimuli.h, src/symbol.cc, src/symbol.h,
	src/tmr0.cc, src/value.cc, src/value.h:
	- Removed debugging statements
	- Added the attribute_symbol class.
	- Added more methods to the derived symbol classes to handle type
	casting.

2004-11-07 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.def, plat/win32/gpsim.nsi, src/makefile.mingw,

	* cli/socket.cc, gui/gui_profile.cc, gui/gui_stack.cc,
	gui/gui_symbol.cc, src/symbol.cc, src/symbol.h, src/value.cc
	src/value.h:
	gpsim symbols now support more of the methods of the Value class.

2004-11-05 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_clear.cc, cli/cmd_disasm.cc, cli/cmd_set.cc
	cli/command.cc, cli/scan.ll, gui/gui_breadboard.cc, src/errors.cc

	Cleaned up the Value class.

2004-11-05 Scott Dattalo <scott@dattalo.com>
	* src/attribute.h, src/attribute.cc, Makefile.am: Removed attribute.*
	from gpsim. The class 'Value' has replaced it.

2004-11-04 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_break.cc, cli/cmd_log.cc, cli/cmd_symbol.cc, cli/cmd_x.cc,
	src/attribute.cc, src/cod.cc, src/expr.cc, src/gpsim_classes.h,

	src/processor.h, src/symbol.cc, src/symbol.h, src/value.cc,
	src/value.h:
	- Rearranged class heirarchy so that gpsimValue derives from
	gpsimObject instead of Value.
	- Substitued the Value class for those places where the Attribute
	class is used.
	* modules/encoder.cc, modules/led.cc, modules/logic.cc,
	modules/push_button.cc, modules/resistor.cc, modules/switch.cc,
	modules/usart.cc, modules/video.cc

	src/pic-registers.cc, src/registers.cc, src/symbol.cc, src/symbol.h,
	src/value.cc, src/value.h:
	Added command line assignments. Now you can write stuff like:
	  temp1 = temp2 << 4
	where temp1 and temp2 are two registers.

2004-11-02 Scott Dattalo <scott@dattalo.com>
	* src/attribute.cc, src/attribute.h, src/modules.cc, src/modules.h:
	cleaned up include dependencies.

2004-11-02 Scott Dattalo <scott@dattalo.com>
	* src/gpsim_time.cc, src/gpsim_time.h: Fixed a bug with clearing

	* src/gpsim_time.cc, src/gpsim_time.h, src/breakpoints.cc, src/ioports.h,
	src/ioports.cc, src/stimuli.cc, src/tmr0.cc: Interrupts, tmr0 and
	I/O pins were all broken in some way.
	* regression/interrupts_14bit.asm, regression/interrupts_14bit.stc:
	Added regression test for the midrange devices

2004-10-29 Scott Dattalo <scott@dattalo.com>

	* regression/instructions_16bit/instructions_16bit.asm: Added
	decf instruction to the regression test.

2004-10-20 Scott Dattalo <scott@dattalo.com>
	* src/ioports.cc, src/ioports.h, src/stimuli.cc, src/stimuli.h:
	PORTB pullups updated.
	Added an overloaded update() member to Stimulus_Node that doesn't
	require time as an input (we never used it anyway).

	* src/stimuli.h, src/stimuli.cc: Began adding capitance modelling
	to stimuli.

2004-10-18 Scott Dattalo <scott@dattalo.com>
	* src/gpsim_classes.h, src/registers.h: Added EXTERNAL_RESET and
	BOD_RESET types.

2004-10-17 Borut Razem <borut.razem@siol.net>
	* plat/win32/gpsim.def: MSVC sync
	* src/symbol.cc: fixed gpsim crash on WIN32 in remove_module()

2004-10-13 Scott Dattalo <scott@dattalo.com>
	* src/cod.cc: Applied patch from Craig Franklin that adds support
	for reading .cod file message area.

2004-10-12 Scott Dattalo <scott@dattalo.com>
	* src/gpsim_time.cc: Added diagnostic printf's
	* src/pic-processor.cc, src/pic-processor.h, src/processor.cc,

	stepping.

2004-10-11 Scott Dattalo <scott@dattalo.com>
	* src/cod.cc, src/processor.cc: Applied, but modified, patch from
	Craig Franklin that brings gpsim up to date with new gputils release.

2004-10-07 Scott Dattalo <scott@dattalo.com>
	* gui/gui_breadboard.cc, gui/gui_breadboard.h, gui/gui_menu.cc:
	Cleaned up the gui breadboard code a little by making the gui_module
	structure a GuiModule class. In addition, new modules are queued
	into the breadboard and realized only after the breadboard has
	been built.

2004-10-07 Scott Dattalo <scott@dattalo.com>
	* gui/gui_src_opcode.cc: window was being built before cpu had been
	initialized.
	* cli/cmd_disasm.cc, src/processor.cc, src/trace.cc: Disassembling
	and tracing had wrong addresses for the 18F family (again...)

2004-10-06 Scott Dattalo <scott@dattalo.com>
	* gui/gui_src.h, gui/gui_src_asm.cc, gui/gui_src_opcode.cc,
	gui/gui_statusbar.cc, src/breakpoints.cc: Fixed breakpoint
	icon refreshing. Also fixed  Source browser window creation if either
	~/gpsim is missing or the registry hasn't been initialized

2004-10-05 Scott Dattalo <scott@dattalo.com>
	* gui/gui_src_asm.cc: Moved the creation of the Search Dialog
	window out of Build() and into its own function. Changed the behavior
	of the signal callbacks to conform to GTK+ 2.X

2004-10-04 Scott Dattalo <scott@dattalo.com>
	* README, INSTALL: Cleaned up stale documentation.

2004-10-04 Scott Dattalo <scott@dattalo.com>
	* cli/input.cc: Send an extra CR to the parser when loading a
	command file. Turns out that when the gui loads a file, the
	parser doesn't process it until another CR is seen.

2004-10-04 Scott Dattalo <scott@dattalo.com>
	* gui/gui_src_asm.cc, gui/gui_regwin.cc, gui/gui_breadboard.cc:
	Removed some debugging printfs.
	* gui/gui_object.cc:
	With GTK+ 2.2.1 under linux, the gtk_widget_show() was losing
	the (x,y) position of the window.

2004-10-04 Scott Dattalo <scott@dattalo.com>
	* gui/gui_breadboard.cc, gui/gui_breadboard.h:
	The breadboard expose events invalidated drawing areas which in
	turn recursively generated expose events. I'm not sure why this
	code worked with GTK+ 1.x

2004-10-04 Scott Dattalo <scott@dattalo.com>

	Work in progress - trying to resolve breadboard start up
	issues with GTK+ 2.X .

2004-10-03 Borut Razem <borut.razem@siol.net>
	* config_win32.h.in, plat/win32/configure_win32.awk,
	  cli/cli.vcproj, src/src.vcproj,

	  gui/makefile.mingw, modules/makefile.mingw, src/makefile.mingw:
	  added configure_win32.awk script, which takes version number from
	  configure.in and inserts them into config_win32.h.in and generates cofig.h
	* plat/win32/gpsim.def: MSVC sync

2004-10-01 Scott Dattalo <scott@dattalo.com>
	* src/processor.cc, src/processor.h, gui/gui.h, gui/gui_regwin.c
	gui/gui_asm.cc, gui/gui_src_opcode.c, plat/win32/make.mingw:
	Stabilizing windows port. Apparently under windows there's a
	problem if you issue too many gui calls to the GTK library. I
	found that this can be mitigated by periodically clearing out
	the gtk event queue.

2004-09-29 Scott Dattalo <scott@dattalo.com>
	* cli/input.cc, gui/gui_menu.cc, gui/gui_src_asm.cc,
	src/modules.h, src/modules.cc, src/processor.cc,
	src/pic-processor.cc, src/pic-processor.h, src/trace.h
	plat/win32/gpsim.def: Clean ups to get the Windows
	port to compile.

2004-09-29 Scott Dattalo <scott@dattalo.com>
	* gui/gui_src_asm.cc, src/pic-instructions.cc: Uninitialized variables
	in the instruction class were causing the source browser to
	place objects beyond the range allocated to the source browser.
	This confused GTK+ 2.x.

2004-09-28 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_load.cc, cmd/input.cc:
	Allow loading of filenames with spaces. (note, gpsim's
	command line interface still does not support this).

2004-09-28 Scott Dattalo <scott@dattalo.com>
	* gui/gui_main.cc, gui/gui_menu.cc, gui/gui_object.cc,
	gui/gui_object.h, gui/gui_regwin.cc, gui/gui_src.h,
	gui/gui_src_asm.cc, src/gpsim_interface.h, M src/interface.cc:
	- Fixed a few bugs caused by upgrading to GTK+ 2.x:
	  -- Window state was not being saved
	  -- Register window font was fouled up
	  -- Source browser pixel position calculations are different
	  There are still some other bugs that need to be fixed:
	  -- The breadboard window somehow prevents the Source browser
	     window from opening
	  -- <control>Q no longer quits
	  -- scrolling in source browser only works if the scroll pane
	     has focus
	  -- The register window cheats in guessing character width.

2004-09-24 Scott Dattalo <scott@dattalo.com>
	* src/processor.cc: save_state() was skipping address 0.
	* src/registers.cc: Bit string encoding has been enhanced

2004-09-15 Scott Dattalo <scott@dattalo.com>
	* gui/gui_regwin.h, gui/gui_regwin.cc: max allowable registers
	is 64k (used to be 4k)
	* gui/gui_src_asm.cc: improperly initialized instructions were
	causing a core dump.

2004-09-19 Borut Razem <borut.razem@siol.net>
	* configure.in: gpsim is configured to link with GTK+ 2.x by default.
	  Use --enable-gtk1 for linking with GTK+ 1.x (deprecated).

2004-09-15 Scott Dattalo <scott@dattalo.com>
	* gui/gui_regwin.cc, gui/gui_src_asm.cc: Fixed ranging checks.

2004-09-15 Scott Dattalo <scott@dattalo.com>
	* src/processor.cc, src/processor.h, src/pic-processor.cc:
	getWriteTT and getReadTT used to return TraceType objects,
	but now they return unsigned ints.

2004-09-15 Scott Dattalo <scott@dattalo.com>
	* src/processor.cc, src/trace.cc, gui/gui_src_opcode.cc:
	- 18f processors' addresses were off by a factor of two in
	disassembly operations.

2004-09-14 Borut Razem <borut.razem@siol.net>
	* cli/cli.cvproj, src/src.vcproj, plat/win32/gpsim.def: MSVC sync
	* cli/makefile.mingw, src/makefile.mingw: MinGW sync
	* plat/win32/gpsim.nsi: corrected revision number to 0.22.3

2004-09-14 Scott Dattalo <scott@dattalo.com>
	* regression/p12ce518/p12c518.asm, regression/p12ce518/p12c518.stc,
	regression/p12ce518/EEdriver.asm: Added a regression test
	for the 12ce518.
	* src/stimuli.cc, src/i2c-ee.cc, src/ioports.cc, src/stimuli.h,
	src/14bit-registers.cc:
	Fixed stimuli so that the 12CE518 internal EEPROM would work.

2004-09-13 Scott Dattalo <scott@dattalo.com>
	* src/i2c-ee.cc, src/i2c-ee.h, src/ioports.cc, src/p12x.cc,
	src/stimuli.cc, src/stimuli.h: Partially check in for work
	on the 12ce518 bug (internal I/O pins).

2004-09-12 Scott Dattalo <scott@dattalo.com>
	* cli/Makefile.am, cli/errors.cc, cli/errors.h:
	* src/Makefile.am, src/errors.cc, src/errors.h:
	Moved errors.* from cli/ to src/
	* src/expr.cc, src/operator.cc, cli/cmd_disasm.cc,
	cli/cmd_set.cc, cli/cmd_x.cc, cli/command.cc, cli/command.h,
	cli/parse.yy, cli/scan.ll:
	Updated the directory path for including errors.h.

	* cli/cli.cvproj, src/src.vcproj, plat/win32/gpsim.def: MSVC sync
	* cli/makefile.mingw, src/makefile.mingw, gpsim/makefile.mignw: MinGW sync

2004-09-11 Scott Dattalo <scott@dattalo.com>
	* configure.in: Bumped the Revision up to 0.22.3 since there
	have been *so* many changes.
	* cli/expr.h, cli/expr.cc, cli/operator.cc, cli/operator.h:
	  - moved to the src/ directory
	* src/expr.h, src/expr.cc: copied from the cli/ directory
	* src/Makefile.am, cli/Makefile.am
	* src/symbol.h, src/value.h, src/symbol.cc, src/value.cc:
	  - It turns out that gpsim's symbols are essentially identical
	to the value objects that were recently added to support
	expression parsing. Since expressions need to handle symbols
	too, I decided to make the Value class a base class for
	gpsimValue. Now, much of what has been written for
	expressions will naturally handle many of gpsim fundamental
	types.
	* src/pic-processor.cc, src/pic-processor.h, src/eeprom.cc,
	src/eeprom.h, src/14bit-registers.cc: The W register, eeprom,
	and option register states were not saved during a processor
	'save_state()' call.
	* src/p12x.cc: internal 12ce518 i2c module was not connected
	correctly.
	* cli/cmd_clear.cc, cli/cmd_disasm.cc, cli/cmd_frequency.cc,
	cli/cmd_log.h, cli/cmd_macro.cc, cli/cmd_module.h,

	Updated the paths to the include files that have moved

2004-09-08 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_x.cc, cli/expr.cc, cli/expr.h, cli/operator.cc,

	 - Added command line comparison expressions.
	* src/pic-processor.cc, src/pic-registers.cc, src/symbol.cc,
	src/symbol.h, src/value.cc, src/value.h:
	- Added support for a generic symbol type.
	- Added the pic PC object to the symbol table.
	* regression/digital_stim/digital_stim.stc:
	The new expression parsing introduced a grammer conflict that
	requires a stimulus data list to be expressed differently.

2004-09-08 Scott Dattalo <scott@dattalo.com>
	* src/14bit-registers.h, src/14bit-tmrs.h, src/breakpoints.cc,

	modules/usart.cc:
	Started adding Triggers and Actions.
	* regression/run_regression.sh: Added the digital_stim
	regression test to the list of tests to run.

2004-09-07 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.cc, src/stimuli.h, cmd_x.cc, cmd_stimulus.cc:
	Digital asynchronous stimuli were not getting the proper voltage
	data values.
	Enhanced the asynchronous stimulus by making the data array an
	array of C++ objects instead of a type casted structured.

2004-09-06 Scott Dattalo <scott@dattalo.com>
	* examples/14bit/analog_stim2.stc, examples/14bit/ap.stc,
	examples/14bit/async_pulse.stc, examples/14bit/async_stim2.stc,
	examples/14bit/dtmf.stc, examples/12bit/gpio_stim.stc:
	- Updated the asynchronous stimulus syntax in all of the example
	startup scripts

2004-09-05 Scott Dattalo <scott@dattalo.com>
	* src/ioport.cc, src/stimuli.cc:
	Applied patch from Robert Pearce regarding I/O Pins and stimuli
	Fixed a couple more issues with I/O pins and contention.

2004-09-02 Borut Razem <borut.razem@siol.net>
	* cli/socket.cc: read complete line before procesing,
	  support for different line endings (LF, CR-FL)
	* cli/cmd_macro.cc: enable compilation on VS 7.1

2004-09-02 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_macro.cc:
	Clarified the help description for the macro command.

2004-09-02 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_macro.cc, cli/cmd_macro.h, cli/scan.h, cli/scan.ll:
	Completed support for parameterized macros

2004-09-02 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_macro.cc, cli/cmd_macro.h, cli/input.cc,
	cli/parse.yy, cli/scan.ll: Added support for parameterized
	macros. This is not completed

2004-09-02 Borut Razem <borut.razem@siol.net>
	* cli/input.cc, cli/socket.cc: socket port to WIN32
	* gpsim/gpsim.vcproj, cli/cli.vcproj, cli/makefile.mingw,
	  gpsim/makefile.mingw: added cmd_macro.* and socket.cc to
	  the project, wsock32.lib dependency

2004-09-01 Scott Dattalo <scott@dattalo.com>
	* cli/parse.yy: Fixed a bug that caused old versions of bison
	to choke.

2004-09-01 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_macro.cc, cli/input.cc:
	Converted the LLInput struct into a class. Now, the macro
	command can invoke a macro and redirect it's output to the
	parser stream.
	* src/trace.cc, src/trace.h:
	Added the ProcessorTraceObject to the TraceObject heirarchy.
	Now, TraceObjects no longer store info about a processor.
	(Thus modules can be processor agnostic.)

2004-09-01 Scott Dattalo <scott@dattalo.com>
	* src/p16x5x.cc: The 16C55 processor was only declaring a
	package of 18 pins (instead of 28).

2004-08-31 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_macro.cc, cli/cmd_macro.h:
	Added the 'macro' command.
	* cli/Makefile.am, cli/parse.yy, cli/command.cc, cli/scan.ll:
	Parser now calls the gpsim command cmd_macro.

2004-08-31 Scott Dattalo <scott@dattalo.com>
	* cli/scan.ll, cli/parse.yy:
	Added language support for macro definitions. (although,
	macros are not yet supported).

2004-08-29 Borut Razem <borut.razem@siol.net>
	* plat/win32/gsim.def, cli/makefile.migw, src/makefile.migw,
	  cli/cli.vcproj, src/src.vcproj: updated
	* cli/errors.h, cli/scan.ll: corrected include paths

	  src/modules.cc, src/modules.h, src/pic-processor.cc,
	  gui/gui_src_asm.cc, gui/gui_statusbar.cc:
	The Module class was overriding functionality provided in the
	gpsimObject class. This caused problems for external processors
	(That is, processors not a part of gpsim).

2004-08-26 Scott Dattalo <scott@dattalo.com>
	* src/gpsim_object.cc, src/gpsim_object.h: New files that
	support the gpsimObject class. This is a base class for
	almost all gpsim objects.
	* cli/viewable.cc, cli/viewable.h: Removed. The functionality
	that was provide by these was moved to gpsimObject.
	* src/Makefile.am, src/modules.h, src/registers.cc,
	  src/registers.h, src/symbol.cc, src/value.cc, src/value.h,
	  cli/Makefile.am, cli/cmd_x.cc, cli/command.cc, cli/command.h,
	  cli/expr.cc, cli/expr.h, cli/parse.yy:
	Added the gpsimObject Meta class.
	Added support for symbolically viewing registers with the 'x'
	command.
	Added support for viewing a range of registers.

2004-08-26 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.cc, src/symbol.cc, src/symbol.h,
	  gui/gui_profile.cc, gui/gui_stack.cc, gui/gui_symbols.cc
	  cli/scan.ll:
	The symbol class is now derived from the gpsimValue class.
	This change allows some of the recent enhancements created
	for other things to be applied to symbols as well.
	* examples/14bit/p16c64_pwm.stc, examples/14bit/portc_stim.stc:
	The PWM module was crashing. I'm not sure why, but I think
	what actually was happening that the example stc file
	was just broken.

2004-08-25 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_trace.cc, src/14bit-registers.cc, src/trace.cc,
	  src/trace.h: Removed a stale option to the trace command
	and added a new option that will allow the decode trace
	buffer to be saved to a file.

2004-08-25 Manuel Bouyer <bouyer@antioche.eu.org>
	* src/stimuli.cc: fixed bug in finding the node voltage when
	3 or more stimuli are attached to a node.

2004-08-24 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.cc: Attaching three or more stimuli to
	one node caused gpsim to hang.

2004-08-24 Manuel Bouyer <bouyer@antioche.eu.org>
	* src/stimuli.cc: Fixed iopin stimulus update.

2004-08-24 Scott Dattalo <scott@dattalo.com>

	  cli/cmd_symbol.h, cli/expr.cc, cli/expr.h, cli/parse.yy,
	  cli/scan.ll, src/stimuli.cc, src/stimuli.h, src/symbol.h:
	The attach command can now accept a list of symbols. Also,
	Nodes and stimuli are now added to the symbol table whenever
	they're constructed.

2004-08-19 Scott Dattalo <scott@dattalo.com>
	* src/processor.cc: writeTT and readTT were not initialized
	in Processor constructor.

2004-08-09 Scott Dattalo <scott@dattalo.com>
	* src/trace.cc, gpsim/main.cc: more experimental code
	* src/attribute.cc, src/attribute.h, gui/gui_breadboard.cc: Some annoying

	* src/14bit-instructions.cc, src/16bit-instructions.cc, src/pic-instructions.cc,
	src/pic-registers.cc, src/trace.cc, src/trace.h: The newly rewritten
	trace printing code was broken. The good news is that while fixing
	it, I found a way to save a little simulation time by not tracing
	the instruction opcodes.

2004-07-29 Scott Dattalo <scott@dattalo.com>
	* src/ioports.cc, src/ioports.h, src/modules.cc, src/registers.cc,

	modules/paraface.h, modules/resistor.cc, modules/resistor.h,
	modules/usart.cc, modules/video.cc, modules/video.h:
	Rewrote the way stimuli are handled. Before, gpsim only used
	a single parameter (more or less) to represent the state of
	an stimulus. Now, two parameters are used. Currently, these
	parameters are designated as the voltage and impedance. Before,
	the single parameter was somewhat similar to a current.

2004-07-20 Scott Dattalo <scott@dattalo.com>
	* src/stimuli.h, src/stimuli.cc: added input leakage modelling
	to I/O pins.

	* src/eeprom.cc: The eeprom memory access object was not getting
	initialized.
	* src/stimuli.cc: applied patch from Manuel Boyer. The IO_open_collector
	was duplicating the base class' job of setting the pin name.

2004-06-02 Scott Dattalo <scott@dattalo.com>
	* cli/cmd_break.cc, src/processor.cc: 18fxxx addressing was broken.

	gpsimValue class virtual.

2004-05-31 Scott Dattalo <scott@dattalo.com>
	* almost all files: Since the Register class and the Instruction class
	are now derived from gpsimValue, all objects that use registers

	abstractness that this change introduces.
	* src/16bit-instructions.cc, src/14bit-instructions.h: Manuel Boyer
	reported two bugs with the 16bit subwf instruction. He fixed one
	(N-bit was ignored) with a patch and I fixed the other (OV bit was

	page. Corresponding info in 'SourceBrowserAsm_Window'.
	Added a new member to the sa_entry structure to keep track of pixmaps.

2004-05-15 Scott Dattalo <scott@dattalo.com>
	* src/pic-processor: If the simulation is started from an address that has
	an execution break, now gpsim will ignore that break.
	* xpm/canbreak.xpm: New xpm that's used to indicate source lines that will
	accept breakpoints.
	* gui/gui_src.h, gui/gui_src_asm.h: Added 'canbreak' XPM to the source
	browser lines that can accept break points. NOTE: this code currently
	leaks memory!

2004-05-12  Manuel Bouyer <bouyer@antioche.eu.org>
	* src/16bit-instructions.cc, src/p18x.cc, src/p18x.h, src/pic-instructions.cc,

	src/trace.h, src/uart.h, gui/gui_profile.cc, modules/encoder.h, modules/paraface.h,:
	Removed the BreakCallBack class. The functionality it was providing is now
	implemented by the BreakpointObject class.

2004-04-11  Borut Razem  <borut.razem@siol.net>
	* src/interface.cc: added initialization of interface_seq_number in
	gpsimInterface constructor.

2004-04-07 Scott Dattalo <scott@dattalo.com>
	* src/breakpoints.h, src/breakpoints: Adding assertion type breakpoints
	and redesigning the whole Breakpoint class.

2004-04-07  Bert Driehuis <driehuis@playbeing.org>
	* extras/lcd/lcd.cc:  reference was made to a no-longer existing API
	* extras/lcd/module_manager.cc: contained comments
	which were out of date, that hampered readability.
	* src/modules.cc: will not load two shared extension modules, if the
	first does not have an "initialize" routine. As a side effect of
	debugging this one, the error reporting of the dynaloader has been
	expanded. The trick turned out to be to clear pre-existing error
	conditions with a dummy call to dlerror(). An alternative
	implementation would call dlerror in an else clause when loading
	"initialize" fails, but doing it like this patch does it has the
	advantage of also dealing with like errors in libraries gpsim might
	use. For a similar situation, look up "not a typewriter" and "perror"
	in Google.
	- did not immediately fail when incomplete linking
	conditions exist. By changing to RTLD_NOW, a bad dynamic module will
	be detected at load time rather than at run time. *** this will break
	broken modules out there that until now appeared to have worked ***

2004-04-04  Arthur Peters <amp@singingwizard.org>
	* src/Makefile.am, src/ssp.cc, src/ssp.h:

	modules port on WIN32

2004-04-03  Borut Razem  <borut.razem@siol.net>
	* src/stimuli.cc: fixed warning C4715: 'IOPIN::get_iop' : not all
	control paths return a value: IOPIN::get_iop() returns 0 in case that
	iopp and iop are NULL

2004-04-01 Scott Dattalo  <scott@dattalo.com>
	* modules/resistor.cc, modules/resitor.h: Several member functions
	in the resistor classes were declared, but not defined anywhere.
	* src/pic-instructions.h, src/breakpoints.h, src/breakpoints.cc:
	adding assertions to the simulator.
	* src/processor.cc, src/processor.h, gui/gui_src_asm.cc: Source
	browser windows can now get a unique name.

2004-03-30 Scott Dattalo  <scott@dattalo.com>
	* numeous files throughout gpsim: The Module class now uses
	a string type instead of a 'char *' for the module name. Also,
	the gui x and y coordinate were removed from the module class (I
	still want to remove the 'widget' member too).
	* modules/usart.cc: calls to the old gpsim api were still lingering
	around here.
	* gui/gui_src_asm.cc, gui/gui_src.h, src/processor.h: more browser
	splitting stuff.

2004-03-29  Borut Razem  <borut.razem@siol.net>
	* src/modules.cc: support of external modules on WIN32

2004-03-25 Scott Dattalo  <scott@dattalo.com>

	The GUI_Object 'name' member has been changed from a char * to a
	private string and is now no longer directly accessed by the derived
	classes. New methods set_name() and and name() control the access.

2004-03-24 Scott Dattalo  <scott@dattalo.com>
	* gui/gui_src_asm.cc, gui/gui_src.h: Added BreakPointList class to handle
	the 3 lists of breakpoints. Removed duplicate code too.

2004-03-23  Borut Razem  <borut.razem@siol.net>
	* src/modules.cc: gpsim on WIN32 doesn't support modules yet

	* regression/run_regression.sh, regression/simulate:
	Fixes to allow regression tests to run on BSD 4.9.

2004-03-01  Bert Driehuis <driehuis@playbeing.org>
	* extras/lcd/lcd.cc:

	* src/icd.cc: include time.h for BSD

2004-03-01 Scott Dattalo  <scott@dattalo.com>
	* modules/* -
	Updated the (internal) modules to comply with the new gpsim interface standard
	* dozens of files:
	  -- removed all references to 'pic_id'
	  -- changed pic_processor references to Processor references


2004-02-29  Borut Razem  <borut.razem@siol.net>
	* src/eeprom.cc: initialization of variable eestate in EECON2::EECON2(void)
	by calling ee_reset()

2004-02-28  Borut Razem  <borut.razem@siol.net>
	* config_win32.h.in : strtoll defined as _strtoi64, removed definition
	of atoll, version number updated to 0.21.2
	* gui/gui.h, gui/gui_stopwatch.cc: prevent calling Update() from Update().
	The problem manifested on GTK+ 2.x on Linux and WIN32.
	* gui/gui_breadboard.cc, gui/gui_regwin.cc, gui/gui_src_asm.cc,
	gui/gui_src_opcode.cc: GTK+ 2.x port - use pango font handling

	* gui/gui_main.cc, gui/gui_menu.cc, gui/gui_processor.cc:
	Inhibit the half-baked gui_scope.

2004-02-27 Scott Dattalo  <scott@dattalo.com>
	* src/pic-processor.cc, src/interface.cc, src/interface.h,
	src/init.cc, src/icd.cc, src/cod.cc, src/breakpoints.cc,
	gui/gui_main.cc, gpsim/main.cc, cli/input.h, cli/input.cc,
	cli/cmd_x.cc, cli/cmd_run.cc, cli/cmd_dump.h, cli/cmd_dump.cc:
	The gpsim library, which is the code comprised of everything
	in the src/ subdirectory, now has no dependencies on the gui

	* gui/gui_stopwatch.cc, extras/rs232-gen/rs232-gen.c:
	changed all references of atoll to strtoll. bug 820326

2004-02-25 Hans-Juergen Dorn <hans.dorn@apl-landau.de>
	* src/16bit-registers.cc: gpsim was pushing onto
	the stack before decrementing the stack pointer. Also,
	the gpsim internally formatted address was being pushed.

2004-02-17  Scott Dattalo  <scott@dattalo.com>
	* gui/gui_scope.cc: expose and resizing kind of work.

2004-02-17  Scott Dattalo  <scott@dattalo.com>
	* gui/gui_scope.cc: taking off the rough edges.

	src/12bit-processors.h, src/12bit-processors.cc
	Added FSR_12 - a new class for the 12-bit core. I also redesigned the
	way FSR and INDF interact.
	* src/p18x.cc - the 18f252 package pins weren't defined.

2004-02-13  Scott Dattalo  <scott@dattalo.com>
	* src/processor.cc, src/processor.h, src/pic-processor.cc, src/cod.cc:

2004-02-11  Scott Dattalo  <scott@dattalo.com>
	* gui/* changed calls to gpsim_* to the C++ interface.
	* src/interface.cc - removed many of the gpsim_* functions
	* src/stimuli.cc, cli/cmd_set.cc - changed calls to gpsim_* to
	the C++ interface.

2004-02-10  Scott Dattalo  <scott@dattalo.com>
	* src/processor.cc, src/processor.h, src/pic-processor.cc, src/pic-processor.h:

	Cleaned up symbol api.

2004-02-09  Scott Dattalo  <scott@dattalo.com>
	* all files!
	'NULL' has been replaced with '0' throughout all of gpsim.
	The reason is two-fold: 1) MAC users were having trouble compiling
	2) Stroustrup says NULL shouldn't be used in C++ :).

2004-02-08  Scott Dattalo  <scott@dattalo.com>
	* src/processor.cc, src/processor.h, gui/gui_src.cc, gui/gui_src_asm.cc,
	gui/gui_break.cc: Fixed 'ProgramMemoryAccess' class for the 18f devices
	* src/16bit-processors, src/p18x.cc: Removed some debug stuff
	* extras/lcd/*: Changed the LCD module from version 0.2.0 to 0.2.1

2004-02-06  Scott Dattalo  <scott@dattalo.com>
	* tons of files changed...
	Removed 'break_point' member from the Register class
	Changed the mechanism for checking how a break point is set on
	a register.
	* gui/gui.h, gui/gui_watch.cc, gui/gui_regwin.cc: modified GUIRegister
	class to adopt to changes made in the break point stuff. Also
	add rma member for getting access to processor registers.

2004-02-05  Scott Dattalo  <scott@dattalo.com>
	* src/pic-processor.h
	Fixed a nasty, nasty bug. The "GP_Processor" pointer in the
	pic_processor class was conditionally compiled. However the
	condition (HAVE_GUI) occurs in the include file config.h. Now
	the bug is that config.h was not included in all cases. Some
	classes were derived from pic_processor with this definition
	while others weren't. Syntactically, everything was okay. But
	the compile had the conflicting information for the size of
	pic_processor class.
	* src/* - whole bunch of other files touched while looking for
	this bug.

2004-02-04  Scott Dattalo  <scott@dattalo.com>
	* src/processor.cc
	Experimenting with operator [] for the ProgramMemoryAccess class.

2004-02-02  Scott Dattalo  <scott@dattalo.com>
	* src/intcon.*, src/processor.*, src/16bit-processor.*
	Fixed the weird bug that was discussed in the 2004-01-30 entry. The
	problem was basically invalid type casting. In the processor class
	heirarchy, there are about 5 or 6 levels of inheritance. Most of
	the time gpsim accesses a processor's details through one of the
	base classes. Sometimes though, an object needs access to somthing
	specific to a processor. In these cases, gpsim would type cast
	a pointer to the specific processor. The bug is that you can't
	safely type cast a base class object into a derived class object
	in C++.

2004-01-30  Scott Dattalo  <scott@dattalo.com>
	* almost all source files - still trying to sort out include
	dependencies. There's a weird bug where gcc is adding an extra
	4-byte offset to pointers in some instances. I have no clue why...

2004-01-29  Scott Dattalo  <scott@dattalo.com>
	* almost all source files - trying to sort out include dependencies

2004-01-28  Scott Dattalo  <scott@dattalo.com>
	* src/pir.h moved all of the PIR*::put()'s to the PIR base class
	* src/intcon.h, src/intcon.cc moved inline functions that called

	* src/pir.cc new file - added so that inline functions that called
	bp and trace objects could be removed from the header file.
	* src/Makefile.am added pir.cc to the list of src files.

2004-01-26  Scott Dattalo  <scott@dattalo.com>

	    - added declarations of exit_gpsim() and get_dir_delim()
	* gpsim/main.cc:
	    - removed declaration of exit_gpsim(), now included in cli/input.h

	* cod.cc:
	    - included cli/input.h for declaration of get_dir_delim()
	    - substr() replaced with get_string(), which gets the string from .cod
	      file. strings in .cod file are represented as:
	      - first byte defines the string length
	      - the string starts at the second byte.
	    - read_src_files_from_cod(): conversion to DOS file name
	    - open_cod_file() opens .cod file in binary mode

	were declared in one giant array.)

2003-11-29  Scott Dattalo  <scott@dattalo.com>
	* src/16bit-registers.cc - Access to PLUSWx are now signed.

2003-11-28  Scott Dattalo  <scott@dattalo.com>

	* gui/gui_processor.cc - use memset instead of bzero.

2003-09-14  Scott Dattalo  <scott@dattalo.com>
 	* src/gpsim_time.h - changed cycle counter break point from a Singly linked
	list to a doubly linked list. This is in preparation for separating module
	time from pic processor time so that when the PIC goes to sleep, time
	doesn't stop.

2003-09-07  Scott Dattalo  <scott@dattalo.com>
	* src/p16f62x.h - duplicate declaration of intcon register

2003-09-07  Scott Dattalo  <scott@dattalo.com>
	* src/breakpoints.cc - this time the 'Too many cycle counter breakpoints' was
	fixed. BTW the problem was that 'clear_break' was not putting the cleared
	breakpoint back into the 'inactive' list

2003-09-07  Scott Dattalo  <scott@dattalo.com>
	* src/pic_processor.cc -- Fixed the "Too many cycle counter breakpoints" bug
	* src/interface.cc        It turns out that the "realtime" stuff was
	* src/breakpoints.cc      1) duplicating a class declaration. 2) not clearing
	* src/breakpoints.h       cycle counter break points.
	* gpsim.sln - added for win32 port.

2003-08-30  Scott Dattalo  <scott@dattalo.com>

	* eXdbm/parse.c - "char" is used to store result of fgetc, but
			EOF doesn't fit in the default unsigned chars.
	* src/cod.cc - an endian issue which made symbol values come out wrong.
		- note these fixes came from a patch attached to an anonymous  bug report

2003-08-18  Scott Dattalo  <scott@dattalo.com>
	* src/ioports.cc - Port A on the F62x devices was named "ioport"
	* src/p16f62x.cc - intcon was not declared at 0x8b (bug 566165)

2003-08-17  Scott Dattalo  <scott@dattalo.com>
	* regression/* started the regression test directory. Only two
	tests are performed: instruction validation for the midrange
	family and a simple node test.

2003-08-17  Scott Dattalo  <scott@dattalo.com>
	* Huge patch from Borut Razem mailto:borut.razem@siol.net that enables

	* TXIF was handled improperly (reported by Wojciech Zabolotny <wzab@ise.pw.edu.pl>)
	* TMR1 was incrementing even when disabled (Reported by Wojciech)
	* Patch from JG for Suse 7.1.
	* Patch from Robert Pearce to add 16C55
	* Sleep now works for 12c5xx.
	* Config word now works for 12c5xx
	* GPIO can wake a sleeping 12c5xx
	* Added pullup/pulldown resistors to the gpsim modules (idea from SET)
	* Numerous patches from from (SET) Salvador mailto:salvador@inti.gov.ar
	* SET - added "frequency" command
	* SET - Added time field to the gui status bar.
	* Carlos Nieves Ónega - Massive patch for the 17cxx core
	* Carlos Nieves Ónega - Registers for 17cxx core
	* From Salvador Eduardo Tropea mailto:salvador@inti.gov.ar
	  * Modified: In gpsim/main.cc put a cast in poptGetContext call, but perhaps
	    is a fault in the version I use of popt, double check it.
	  * Added: gtk_window_set_wmclass calls to help Enlightenment to remmember the
	   positions of the windows.
	  * Added: In gui/gui_main.c a couple of #undef to avoid redefinitions in
	    eXdbm.h. Also check if that's OK for the eXdbm you are using.
	  * Modified: Moved the INTCON register from _14bit_18pins class to child
	    classes. That's because I needed to inherit from it and P16X6X_processor
	    and both defines INTCON. I also think things are more clear in this way.
	  * Fixed: A bug in the A/D routines. If you started a conversion at the same
	    time you were enabling the A/D this conversion was aborted. To fix it I
	    transfered new_value to value before calling start_conversion().
	  * Added: Partial support for 16C712 and 16C716 CPUs, they inherit from 14bits
	    18pins processors because they have 18 pins and also from 16x6x because
	    they have TMR1, TMR2 and Capture/Compare facilities like in 16C63. I could
	    check it deeply, just the A/D part. I also didn't implement the DATACCP and
	    TRISCCP registers, I don't know how they work, but I think they control the
	    use of some I/O pins (normal or CCP function).

    gpsim's version.
  o Enhanced 'it.asm' and added 'it_12bit.asm' - two routines that exercise
    gpsim's ability to simulate the pic instructions.
  o Added a trace for skipped instructions (before you'd see skipped instructions
