/C-Compiler

Compiler built using C++, Flex, and Bison that compiles a subset of C90 into MIPS1 assembly with additional support to translate into Python3

2019/2020 Compilers Coursework

There is a single assessed code deliverable, which is due on Tue 24 March at 23:59. This deliverable contains two components:

  • C-translator (35%): Your compiler will be able to translate a subset of C into equivalent Python. This allows each submission to demonstrate lexing and parsing functionality, even if the code generation is weak.

  • C-compiler (55%): 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, so the lab Ubuntu distribution, or equivalently an Ubuntu 16.04 VM as configured in the attached Vagrantfile.

Associated with all deliverables is a

which will be assessed orally at the start of Summer term.

Repositories

Each group gets a bare private repository. It is up to you if you want to clone the master specification, or to start from scratch.

Submission

Submission will be via GitHub (code) and Blackboard (commit hash), as in the lab.

All submissions will be tested functionally -- there is no expectation for your compiler to optimise its input. Moreover, your compiler will only be tested on valid inputs, so you do not need to handle faulty inputs in a graceful way.

Changelog

  • New for 2019/2020:

    • In previous years, students were additionally required to submit a set of testcases. This deliverable has been removed; instead, a large collection of testcases has been provided for you, as this was judged to be more useful.

    • In previous years, the compiler component counted for 42.8% of the module; it now counts for 55%. It was felt that this weighting more accurately reflects the effort that students put in to building a working compiler.
