cparser - A C99 parser (with GNU extensions)
============================================
Introduction
------------
cparser is a recursive descent C99 parser written in C99. It contains a
preprocessor, lexer, parser, constructs an AST and does semantic analysis. It
acts as a frontend to the libFirm intermediate representation library. This
way optimization and code generation is performed. The compiler supports cross
compilation to multiple target architectures with a command-line switch. It
comes with driver logic for calling assemblers and linkers as well as parsing
command-line options. This allows it to be a drop-in replacement for gcc or
clang in many situations.
Building and Installation
-------------------------
Requirements:
* A C99 compiler (gcc and icc are known to work).
* libFirm-1.22
### Building with make
Unpack libfirm in a directory called libfirm in the source directory
alternatively you may setup an alternate location with a 'config.mak' file.
Just type 'make' in the source directory. The results are put into a directory
called "build". You can override the existing preprocessor, compiler and linker
flags and built-in paths for include directories by creating a 'config.mak'
file.
### Building with cmake
cparser has an additional cmake build system. CMake is a complexer build system
than the make based build and most cparser developers do not use it. However
it can adapt the compiler and linker flags to build shared libraries for a
wider range of systems, provides an installation target and is often more
familiar for people preparing packages for distribution.
### Notes for a cparser installation
While cparser often runs fine from the source/build directory, a proper
installation should be configured with correct system paths. For this a
`config.mak` file should be created and the following variables set apropriately
for the system: `PREFIX`, `SYSTEM_INCLUDE_DIR`, `LOCAL_INCLUDE_DIR`,
`COMPILER_INCLUDE_DIR`, `MULTILIB_M32_TRIPLE`, `MULTILIB_M64_TRIPLE`,
`variant=optimize`.
The variable may be defined empty; See `config.default.mak` and `Makefile` for
details.
