C99 compiler using libFIRM as backend

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 locations
    • 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
