bm_core_piler

Cminus compiler for the BM_CORE architecture designed using Python3 and Antlr4 used as the final project for the Laboratory of Compilers lecture.

How to use it

1. Install pipenv

2. Install Antlr 4.7

3. Clone this repository

4. cd into the repository

5. Execute pipenv --python python3.6 install to install the dependencies

6. Execute antlr4 -Dlanguage=Python3 -visitor -o bm_core_piler/gen cminus.g4 to generate the grammar parser

7. Execute pipenv run python -m bm_core_piler --<option> --file programs/<file_name>.cminus

Notes and options

The compiler runs as a Python module, so you always have to run python -m bm_core_compiler to execute it

To run the lexical analysis, use the option --lex

To run the syntactic analysis, use the option --syn

To run the semantic analysis, use the option --sem

To run the compiler over a file, use the option --<file_name>

Synthesizing

To synthesize the Cminus language use the option --synth

To specifie the initial memory position from which data will start to be stored use the option --mem <int_number>

Once you run, for example:

pipenv run python -m bm_core_piler --synth --mem 100 --prog --file programs/PROGAM_FILES/prog_1_pow_net.cminus

for synthesizing a program, or:

pipenv run python -m bm_core_piler --synth --file programs/SYSTEM_CODE/BM32OS.cminus

for synthesizing a system file, to finish translating the generated assembly to it's respective binary values, run:

./bin_script.sh

Notes

Finally, huge thanks to Ivan for helping on this project at it's early days.
