Meo subset c compiler

Let's start

• meo is 🐱 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.

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.

Todo list

• Run basic math operator +,-,*,/ on X86_64 GNU/Linux -> v0.1
• Compile clgt.c
• Support IF statements -> Can compile if_stmt.c
• Support WHILE statements. -> Can compile while_stmt.c
• Support FOR statements. -> Can compile for_stmt.c
• Support function & function call.
• Global variable & local variable.
• Structure type.
• Full operator (&& & || | ^ !).
• Self compile.
