A second attempt at writing a compiler in C, to learn about parsing, lexical analysis, context free grammars, abstract syntax trees, code generation, and all sorts of other stuff involved with writing a compiler.

Compiles a subset of C to x86 assembly.

Compile with make and then run ./i8c file.c to compile the file using i8c. This creates an assembly file file.s, which can be assembled using GCC, it will also print out the AST created.

There are some tests that I wrote to have some protection against regression faults. They can be run with make test.

This does not actually conform to any official C language standard. Atleast for now it's more of a compiler for a 'C-like' language then exactly C.

It's for learning purposes, not actual use.

• A Preprocessor
• Casting
• Arrays
• Typedefs
• Enums
• Lots more...
