2018/2019 Compilers Coursework

There is a single assessed code deliverable. This deliverable contains three components:

• [Test suite]: A bash script that runs the basic C funcionality tests in test_deliverable/test_cases.

• [C-translator]: This compiler is able to translate a sub-set of C into equivalent Python.

• [C-compiler]: This is a compiler from C to MIPS assembly.

In all cases, the source language is pre-processed C90. The target environment is Ubuntu 16.04.

C-compiler features

Here is a list of basic features that the compiler handles:

• a file containing just a single function with no arguments
• variables of int type
• local variables
• arithmetic and logical expressions
• if-then-else statements
• while loops

And here is a list of the intermediate features that the compiler also implements:

• files containing multiple functions that call each other
• functions that take up to four parameters
• for loops
• arrays declared globally (i.e. outside of any function in your file)
• arrays declared locally (i.e. inside a function)
• reading and writing elements of an array
• recursive function calls
• the enum keyword
• switch statements
• the break and continue keywords

Using the test suite

To run the test suite for the compiler, simply type ./c_compiler_test_suite (and make sure it has permission enabled using chmod u+x). To extend the test suite, add a pair of .c and _driver.c files to the test_deliverable/test_cases folder.
