compiler-1's Introduction

编译C语言的一个小型编译器

详细要求见http://os.hit.edu.cn/?p=7

LOGS:

--------V2.0------------

  • 支持词法分析、语法分析、语义分析、生成汇编
  • 最终输出AT&T格式的汇编代码

--------V1.0------------

  • 实现了基本的词法分析和语法分析
  • 输出Tokens和语法分析树

用法(假设源文件为source.c)

  • 帮助:

    python compiler.py -h

  • 查看词法分析结果:

    python compiler.py -s source.c -l

  • 查看语法树:

    python compiler.py -s source.c -p

  • 生成汇编:

    python compiler.py -s source.c -a

  • 将汇编文件编译成二进制:

    gcc source.S -o source

注意:

生成的汇编文件仅能在linux在编译,OS X虽然是unix like, 但是其gcc编译器与linux下的生成语法不同

TODO:

只实现了该网站中出现的语法句型,还有很多语法状态没有实现。 比如,不支持嵌套的控制语句等。

Test Environment

  • Ubuntu 12.04
  • Python version: 2.7
