Requirements:

1. QEMU MIPS Emulator: install using sudo apt install qemu-user
2. MIPS Reference Compiler: install using sudo apt install qemu-user
3. Bison: install using sudo apt install bison
4. Flex: install using sudo apt install flex
5. MIPS Linux GNU: install using sudo apt install gcc-mips-linux-gnu

Usage:

The compiler can be built by running the following command in the top-level directory:

make bin/c_compiler

The compilation function is invoked using the flag -S, with the source file and output file specified on the command line:

bin/c_compiler -S [source-file.c] -o [dest-file.s]

compiler_tests:

Contains a large number of example inputs, divided into various categories. The following scripts can be run to test the compiler on the testcases:

1. Run one testcase: ./test_compiler <name-of-testcase>
2. Run all testcases: ./test_compiler
