| Simple Inline Assembler Instructions

The simplest form the `asm` keyword is:

    asm ("instructions");

where instructions contains one or more assembler instructions separated by semicolons or newlines.
In TIGCC, all register names must be preceded by a percent sign, to avoid confusion with C variables named like one of the CPU registers. For example:

    asm ("move.l 0xC8,%a0; move.l (%a0,1656),%a0; jsr (%a0)");

Hexadecimal constants must be written according to C syntax (like `0xC8`), not using the notation `$C8` which is common in various assemblers.
Note that something like

    asm ("move.l 0xC8,a0");

will be interpreted quite differently: `a0` will be regarded as a C language variable, not a register! Read the documentation about the GNU Assembler for more information about the exact syntax and directives which it accepts; since inline assembler instructions are copied directly into the output of the compiler, exactly the same features are available.
Newlines as separators are also accepted in instructions, so the following code is valid as well:

    asm ("   move.l 0xC8,%a0
             move.l (%a0,1656),%a0
             jsr (%a0)");
