Meo subset c compiler

Let's start

• meo is :cat: in Vietnamese, but now it is subset c compliler
• The project is mainly used to study compiler.
• I use 100DaysOfCode strategy, that will make small step everyday by rule
• I study base on following.
  • Reading Compiler design in C - Allen I.Holub
  • Reading Dragon book
  • Reference A Compiler Writing Journey

Design

• Using design as four-pass compiler, which is refered from Compiler design in C - Allen I.Holub
• Each module lexical analyzer, parser, code generation are designed as independent module, it can be easy to replace without any effect other part.
• Each module is designed as multi instance, I plan supporting paralell compiler to increase performance.

Implementation

• First step: only supporting X86-64 + pass 2 (lexical analyzer, parser, code generation).
• Using back end of GCC to generate executed code.
• Using TDD with catch2.
• Using Google coding convention.

Current status.

• Can compile all files in sample, ex fibonacci.c
• Can compiler recursion, as the fibonacci recursion version recursion.c

Todo list

• Support function.
• Function call.
• Global variable & local variable.
• Structure type.
• Pointer.
• Function pointer.
• All operator.
• v..v...
• Self compile.
