py2aqa32

Python Compiler to AQA Assembly as implemented by Peter Higginson at https://www.peterhigginson.co.uk/AQA/.

main branch should compile accurately but not optimally the code in test_code.py.

The official instruction set is found here. This compiler aims to run on the Peter Higginson simulator as documented here. Note that he has expanded upon it to make a working simulation - if they ever differ the Higginson version is preferred.

Supported Syntax

test_code.py contains an example of every supported Python construction, but not every permutation.

Unsupported syntax is ignored and no error is raised.

  • Integer variables only (PH treats them as signed).
  • Assignment (of the forms a = b and a += b).
  • Integer Addition and Subtraction - but the result must be assigned to a variable.
  • Comparisions - but the result must be used in a condition.
  • While loops - those of the form "while False" are optimised out.
  • if/elif/else - as above.
  • Comments - this is a consequence of using the ast Python parser in the stdlib.

TODO.md contains plans and discussions for remaining syntax and constructions.
