youngzhou1999 / cminus-compiler

this is a compiler for C-minus which is a subset of C language.

C- Compiler

A simple compiler aim at C-minus language and TM vitrual machine.

File Structure

1. main.c -- main code file

2. globals.h -- define data structures and macros

3. scan.l, parse.y -- lex and yacc source code for quick scanning & parsing

4. AST.c -- define routine functions for parsing a syntax tree, making type-check and error-handling at meanwhile.

5. symtab.c -- define data structures for symbol tables (for variables & functions)

6. codegen.c -- code generator, which recursively generates TM-machine code by syntax tree travesal.

Usage

1. To compile the compiler:

   make clean make

2. To compile for C-minus code:

   main [filepath] e.g. main test1.cm

3. To run TM codes:

   tm [filepath] e.g. tm test1.cm.tm
