C89 to MIPS compiler

Usage

• use provided Vagrantfile to create a desired environment
• build compiler make bin/c_compiler
• build and run Catch2 unit testing make test or make bin/test && bin/test [accepts catch2 options]
• run test cases and output csv ./test ref|our
• run test cases and output in a table format .\test_column ref|our
• option ref uses the reference gcc compiler
• optin our uses our compiler

Using our compiler

usage:
  c_compiler <input> options

where options are:
  -?, -h, --help       display usage information
  -c, -S, --compile    compile from C98 to MIPS
  -t, --translate      translate from C89 to Python
  -o <output>          place the output into <file>
