This repository contains example code and test cases for the CSE 40243 compilers course at the University of Notre Dame.

• calc0 contains an incorrect example that attempts to parse arithmetic expressions using bison, but is full of shift-reduce conflits.

• calc1 contains a correct example of using bison and flex together to parse and evaluate simple arithmetic expressions, by computing results as they are parsed.

• calc2 contains a more complex example of using bison and flex to parse arithmetic expressions and convert them into a simple abstract syntax tree of expressions. This would be a good place to start as you design your compiler.

• cminor contains the starter code for the CMinor project, starting with the AST for the parser assignment.

• tests contains the hidden instructors' tests that were used to evaluate each programming assignment.
