BUAA-Compiler-Design

0x00 Introduction

Course work (a C0 compiler) for BUAA B3I063410 Compiler Design.
Students will be required to design and implement a C0 compiler in 6 weeks, step by step. From lexical analysis, syntax analysis to semantic analysis (Quaternary mid-code generation included) and finally, to mips code generation and optimization.

0x01 File Structure

• Source Code
  • Final release version
  • No optimization version
• Documents
  • My design thoughts
  • Software Documentation
• Test input
  • Some test programs
• C0 grammer.txt
  • Detailed C0 grammer requirements

0x02 Usage & Settings

Usage

This is a Visual Studio 2017 projects, you could open it directly with VS17. Once you start the program, you could press directly to compile the default 15061200_test.txt or you could input the full path of your own test program. The compiler's output should include:

File Name	Contents
output_after(before).asm	Mips code
syntac_output_after(before).txt	Quaternary Mid Code

After that, you could run the generated mips code with Mars_refreshfix.jar.

Settings

In SyntacticAnalyze.cpp, you can decide whether to optimize the output or not.

#include "genMips.h" 
//#include "genMips_opt.h"

In myconst.h, it's on your choice that

const bool Verbose = true;// if true then no detailed syntac info output in console 
const string Subfix = "before";// set this to after and your output file will be named with subfix '_after'
const string Newline = "";//Newline = "\\n" if you want to beautify the mips runtime output (automatic line feed)

0x03 Thoughts

1. Start earlier and make your own plan !
2. Don't forget what you have learnt in class.
3. Review your design with pens and papers (debug from higher level) and don't rely too much on testing.

Many thanks to my dear friend @ZhaoYi1031 who inspires me a lot. Also, great work by Pete Sanderson (programming) and Ken Vollmar. Their MIPS Assembler and Runtime Simulator (Mars) runs smoothly.
