c-subset

A compiler for a subset of the C language that compiles to casm machine code

Note: this project is at a very early stage, it is not even close to being complete, the code is unorganized and missing explanation comments

Usage

gcc main.c -I./include -o compiler.bin
./compiler.bin tests/main_test.c
