My toy c compiler.
Based on the book by Rui Ueyama.
The ucc compiler targets the x86_64 architecture only.

ucc implements these stages of compilation
ucc uses cpp to pre-process the source code, as to assemble the generated code and cc to perform linking.
The assembly produced by ucc is written in the Intel syntax.
ucc is self-hosting (i.e. it is capable of compiling itself) - with some slight cheating implemented by the stage2.sh script, which pre-pre-processes the ucc source code before it is passed to the stage 1 compiler for compilation (TODO).
The stage 2 build of ucc is capable of passing all the compiler tests contained in this repo.
