This repository contains a compiler for the C- language written for the Compilers course offered at the University of Guelph (CIS4650) in Winter 2017.
Browse this repository at your own risk if you are taking this course. I do not recommend copying anything from here verbatim as this is not a perfect solution. There are quite a few errors in this code (especially in the generation of assembly code).

To build the program, simply navigate to the directory that this README is located in and run 'make'
Note: The program requires CUP, whose location should be added to the Java classpath in the Makefile. Currently, it is set to:
CLASSPATH=-classpath /usr/share/java/cup.jar:.
Run make clean to delete all build files.
To run the project, first build it by running make.
Then, run the following command, substituting the CUP classpath for
the location of CUP on your machine:
java -classpath /usr/share/java/cup.jar:. CM input.cm
To print out the Abstract Syntax Tree, use the command line option -a:
java -classpath /usr/share/java/cup.jar:. CM -a input.cm
To print out the Symbol Table that is generated when parsing, use the command line option -s:
java -classpath /usr/share/java/cup.jar:. CM -s input.cm
To generate the Assembly code, use the command line option -c:
java -classpath /usr/share/java/cup.jar:. CM -c input.cm
Ten test files: [1234567890].cm are included in the test directory.
[1234].cm will compile properly without errors and can generate
assembly code.
[567890].cm contain multiple syntax and semantic errors and will
not generate assembly code.
They can be executed by running the above commands from the previous section on the test files.
For this checkpoint, we built upon our work from Checkpoint One and Two.
For the first checkpoint we used Professor Fei Song's provided code as a starting point to build the project. We also followed the recommended syntax tree structures for the C- language from the course slides.
