Create a code generator for arithmetic expressions

Your program should accept C source code for a function containing integer arithmetic on stdin, and generate MIPS assembly for the function body on stdout.

Input Format

The input format and constraints are the same as for the tokeniser, with the following restrictions:

  • the only data-type that will occur is int

  • there are no control-flow statements

  • there are no function calls

  • all arithmetic is integer arithmetic

  • there will be a single function with two integer arguments

Output Format

The output format is MIPS assembly, suitable for compilation with GCC MIPS. The calling convention should be compatible with the MIPS gcc toolchain.

Program build

From your top-level directory, doing:

make bin/c_codegen

should create a programe called... bin/c_codegen.

Getting Started

If you want to see what the assembly for a function should look like, then try running a mips compiler. It will include lots of extra information, but the core parts will be there.
