Cimple Compiler

SUMMARY

Cimple is a simplified version of the C programming language with educational purposes.
Its capabilities are limited, however, it contains many well-known control flow statements.
Cimple program files have a .ci extension. A full language description can be found in the report
file (GR). The compiler was developed for the Compilers course @cse.uoi.gr and
the final code produced is in MIPS32 assembly.

CONTENTS

• cimple.py: the compiler
• cimple-test-files: various Cimple programs used for testing purposes
• compilation-output: examples of the files created from the compilation
• report: thorough project report.
• cleanup.py: used to clean any unwanted files created from the compilation
  
  

EXECUTION

• Run command: python3 cimple.py <cimple file> <optional arg>
 <cimple file>: the cimple program file path to be compiled ending in .ci
   <optional arg>: can be one of the following
     -lex: print lex tokens on screen
     -ic: print intermediate code quad on screen
     -st: print symbol table on screen
     -asm: print final assembly code on screen

• By default the compiler creates 3 files:
    .int file with the intermediate code
    .sym file with the symbol table
    .asm file with the final MIPS assembly code

• If the cimple program has no function or procedure an extra C file equivalent is created
  which contains the intermediate code quads as low level C code. (can be compiled with any C compiler)

• The produced final code can be assembled and executed with MARS 4.5:
  MIPS Assembler and Runtime Simulator
  
  

LANGUAGE
