Structure:

pascal.l - FLEX Tokenizer pascal.y - BISON Parser (LALR(1) Parsing) ast_structs.c & .h - Data structures for AST symtab.c & .h - Symbol & Symbol table data structure semantic.c & .h - Symbol table, type checking (semantic validation) translate.c & .h - Translation into LLVM IR utility.h - Some utility functions

Usage of program is as follows: Build using: make or make pascal Clean up: make clean Usage: ./pascal "pascalprog.pas"

Outputs: pascal.ll as a translated .ll file
