sic-compiler

sic, short for simplified C, is a language designed for the course project of Compilers taken during Monsoon 2019. Its context free grammar can be found in the manual.

This repo contains a lexical analyzer and parser, written using Flex and Bison. These were used to construct an abstract syntax tree using the visitor design pattern. Contains a visitor that formats obfuscated source code, one that interprets the source code, and one that generates LLVM IR(ongoing).
