Cfront 3.0.3

AT&T/Bell Labs C++ to C translator from 1994, modified to build on modern hardware

This repo contains the source of cfront and the c++filt demangler. It's currently being used to research how Kirby 64 implemented its C++ code, and will eventually be integrated into the project as a middleman translator.

cfront currently depends on an ancient version of yacc to build correctly, since the syntax has changed since 1994, and using a version from that era is a lot easier than learning yacc syntax and rewriting the 3000 line file in a way that both works and is still compatible with the rest of the codebase

Build Instructions

• Install g++-7, g++-7-multilib, and make
• Get SGI yacc and qemu-irix (cloning and building Kirby 64 decomp will get you both of these)
• Build with make IRIX_ROOT=path/to/kirby64/tools/ido7.1/

Running

• ./cfront < source_file.cc > out_processed.c

Contributing

• Pull requests are welcome, especially to get these files compatible with modern g++. Be sure to run clang-format -i on the files you change to have them follow a sane coding style. Original non-formatted source files are here.
