Compilers Project (Group 7B)

👥 Group members

  • Isabel Amaral (up202006677)
  • Mariana Rocha (up202004656)
  • Milena Gouveia (up202008862)

👩‍💻 Distribution of work

  • Isabel Amaral (33%) - Jasmin
  • Mariana Rocha (33%) - Ollir
  • Milena Gouveia (33%) - Semantic Analysis and Optimizations

🪛 Implemented optimizations

  • Option -o:
    • constant propagation
    • constant folding
  • Option –r=<n> (register allocation):
    • n ≥ 1: the compiler tries to use at most <n> local variables when generating Jasmin instructions. It aborts and reports an error if <n> is not enough to store the local variables.
    • n = −1: This is the default value where the compiler uses as many variables as originally present in the OLLIR representation.

🔎 Self-assessment

The developed project seems to be working as expected except for the optimization where the compiler tries to use the fewest registers as possible (option -r 0). However, considering that all the project requirements and all the remaining optimizations were implemented, we believe that our project deserves a grade of 19-19.5 out of 20.
