C-To-MIPS Compiler

A C to MIPS compiler based on the ANSI C specification and developed in C++.

This project specifications is based on ELEC50010: Instruction Architecture and Compilers [https://github.com/LangProc/langproc-2019-cw.git].

Deliverables

The deliverables consists of the following:

• compiler.cpp: Compiles a given ANSI C program into MIPS assembly language.
• test_compiler.sh: A testbench for the compiler that uses the test cases in the compiler_tests folder and compares the generated MIPS assembly language with MIPS-QEMU.

Compiler

The development of the compiler was inspired based on the ANSI C Yacc Grammer published by Jeff Lee [https://www.lysator.liu.se/c/ANSI-C-grammar-y.html].

The compiler is composed of two main file: lexer and parser. The compiler file dependencies is shown below:

compiler.cpp
|-- lexer.flex
|-- parser.y
    |-- ast_context.hpp
    |-- ast_declaration.hpp
    |-- ast_expression.hpp
    |-- ast_primitive.hpp
    |-- ast_statement.hpp

Building

The compiler is compiled through the Makefile by calling the following commands through the Linux terminal:

make clean 
make all

Testbench

There are three types of testbenches written in Linux bash:

• test_testcase.sh
• test_folder.sh
• test_compiler.sh

Building

Each testbench script can be executed through the Linux terminal such as:

./test_testcase.sh
