Swiss Water Compiler

A Decaf compiler targeting mips assembly written in pure python.

Use

To use the compiler simply import compile_decaf and pass in the source code string as an argument. The resulting assembly will be returned as a string.

from src import compile_decaf
with open('SRC_CODE_PATH') as f:
    code = f.read()
    output = compile_decaf(code)
    with open('OUTP_PATH', 'w+') as o:
        o.write(output)

Tests

There are two test scrips kindly provided by the TA team for Dr Bahrami's fall 2021 compiler design course To run each set of tests change directories to the location of the script and run it.
Note: You will need the required packages in requirements.txt to run the lexer tests and spim to run the code-gen tests

Lexer Tests:

cd ./test/lexer
./run.sh

Code Gen Tests:

cd ./test/cgen
./run.sh

Development

Currently Supports:

• I/O statements
• variable declaration and assignment
• simple arithmetic operations

Future Features:
