Compiler from C to MIPS

C compiler

An implementation of a C compiler that takes C90 source code as input and produces MIPS assembly as output. The output can be linked and assembled to binary using tools such as gcc. The binary is then ready to be run on any MIPS CPU or MIPS emulator and should produce the same results as a binary purely compiled with gcc.

Flex 2.6.0 and Bison 3.0.4 are used for implementing lexer and parser respectively. Older versions might work as well. The actual code generation is performed using C++11.

Build

Run make bin/c_compiler

Running

The bin/c_compiler executable takes C90 preprocessed source code on stdin and produces MIPS assembly on stdout
