CS335: Compiler Design

Creating a C compiler for x86 machines in python

Requirements

• Install python-2.7 and pip2 in your machine
• Install ply : pip install ply
• Install pydot : pip install pydot

Usage

For generating parse tree on test example

• cd <project-top>/src
• python2 cparser.py ../test/<filename> <graph_name.png> Graph will be generated in the test directory

For generating .S files for given .C file

• cd <project-top>/test
• python2 ../src/code_generation.py <filename>

Output files named a.S will be generated. Which can be further used by assembler to generate .out binary file.

• ./run.sh
