Converting a pseudo C source code to a pseudo assembly code

For more information, read the PDF files which are located in this repository (they're in Persian language).


pip3 install -r requirements.txt


python3 input_file_name.c

Sample input (pseudo C source code):

Check out sample.c in the repository (to see the language features).

Sample output (pseudo assembly codes):

  • This project was done by Ali Mirjahani and Erfan Alimohammadi in 2019 for the Shahid Beheshti University Compilers Course project.
  • You can modify the codes and produce your own programming language. There are not much hard-codes, so editing the language grammar would be easy. Grammar rules files have ".in" extension in the repository.
  • There are no switch-case statements in the scanner finite-state machine part. Just draw your DFA graph on a paper, and enter the graph nodes and edges in the scanner; it will work for you! So, modifying scanner DFA (adding and removing edges) doesn't take time from you.
  • This project uses a LL(1) parser (which is implemented by us) and a LALR parser (which is lark-parser, for parsing the boolean expressions). It switches between these two parsers, according to its state.
You can’t perform that action at this time.
