cparser is a recursive descent C99 parser written in C99. It contains lexer, parser, constructs an AST and does semantic analysis. It is currently used as a frontend to the libFirm intermediate representation, but can be used independently. cparser is able to bootstrap itself. It currently uses an external preprocessor. * fast recursive descent parser, parses C90 and C99 * handles most GCC extensions, e.g. __attribute__, inline assembler, computed goto, statement expressions * handles some MSVC extensions (like declspec) * provides many useful warnings * format string checker for char and wchar_t * unreachable code analysis * missing return statement check, which pinpoints exact location(s) * write-only/-self variables detection * missing and redundant forward declarations * most warnings switches, which are available for GCC * provides concise messages in case of error, for example when encountering misspelled typenames * compiler driver compatible with GCC (-fxxx, -Wxxx, -M, ...) * uses libFIRM for optimization and code generation (devel/libfirm) WWW: http://sourceforge.net/projects/cparser/
