C compiler toolchain targeting Linux x64, written from scratch in C. Many features are missing, but it is complete enough to self-host.

(Self hosting is temporarily broken while working on float support)

Includes:

• libc
• C frontend
• SSA form IR
• x64 backend
• x64 Assembler (for the in-memory format, and for textual assembly)
• ELF object file output
• Linker
• ar clone

Build-time dependencies:

• A C compiler
• nasm
• Python 3

To build, run build.py. There are various subcommands for running tests, static checks, bootstrapping, etc. See build.py --help for more info.
