llvmc - The LLVM Compiler Driver (WIP) llvmc [options] filenames... llvmc is a configurable driver for invoking other LLVM (and non-LLVM) tools in order to compile, optimize and link software for multiple languages. For those familiar with FSF's gcc tool, it is very similar. Please note that llvmc is considered an experimental tool.

Built-in Options
LLVMC has some built-in options that can't be overridden in the configuration libraries. Output file name. Specify the language of the following input files until the next -x option. Load the specified plugin DLL. Example: -load $LLVM_DIR/Release/lib/LLVMCSimple.so. Enable verbose mode, i.e. print out all executed commands. Check the compilation for common errors like mismatched output/input language names, multiple default edges and cycles. Hidden option, useful for debugging. Show a graphical representation of the compilation graph. Requires that you have dot and gv programs installed. Hidden option, useful for debugging. Write a compilation-graph.dot file in the current directory with the compilation graph description in the Graphviz format. Hidden option, useful for debugging. Write temporary files to the current directory and do not delete them on exit. Hidden option, useful for debugging. Print a summary of command-line options and exit. Print a summary of command-line options and exit. Print help even for options intended for developers. Print version information and exit. Read command-line options from file. The options read are inserted in place of the original @file option. If file does not exist, or cannot be read, then the option will be treated literally, and not removed. Options in file are separated by whitespace. A whitespace character may be included in an option by surrounding the entire option in either single or double quotes. Any character (including a backslash) may be included by prefixing the character to be included with a backslash. The file may itself contain additional @file options; any such options will be processed recursively.

Control Options
By default, LLVMC is built with some standard configuration libraries that define the following options: Use Clang instead of llvm-gcc. Enable optimization with opt. Add a directory to the header file search path. This option can be repeated. Add directory to the library search path. This option can be repeated. Link in the library libname.[bc | a | so]. This library should be a bitcode library. Make the output be LLVM bitcode (with -c) or assembly (with -S) instead of native object (or assembly). If -emit-llvm is given without either -c or -S it has no effect. Pass options to assembler. Pass options to linker. Pass options to opt. If llvmc succeeds, it will exit with code 0. Otherwise, if an error occurs, it will exit with a non-zero value. If one of the compilation tools returns a non-zero status, pending actions will be discarded and llvmc will return the same result code as the failing compilation tool. llvm-gcc, llvm-g++, llvm-as, llvm-dis, llc, llvm-link Maintained by the LLVM Team (<http://llvm.org>).
