Theseus is:

1. A compiler that translates 32-bit Windows x86 code to Rust.
2. An implementation of some of the win32 API used by the above.

Together, Theseus takes in a .exe file and turns it into a native binary that doesn't depend on x86 or Windows.

I wrote a longer blog post motivating the project.

Theseus is very experimental and probably won't work on a program you try.

• tc/: "theseus compiler", exe to Rust generator
• exe/: (mostly) generated exe code for a few test executables, the output of tc
• runtime/: runtime x86 support for the generated programs
• win32/pe/: PE (.exe format) parser
• win32/winapi/: Windows API implementation (e.g. kernel32, user32)
• win32/derive/: some Rust macros for winapi

The two halves of Theseus are:

1. The tc compiler uses the PE loader to load a .exe file and generate source code under exe/.
2. Building an exe relies on runtime for support for x86 operations and win32 for Windows API.
