MiniJava-Compiler

A compiler for MiniJava, a subset of Java. MiniJava is designed so that its programs can be compiled by a full Java compiler like javac.

Usage

  • make: Compiles all files for the MiniJava compiler
  • make test: Runs the MiniJava compiler in every test file and creates the file test_results.txt with the results in the root directory
  • bash ./runLLVMTests.sh : Runs all .ll files generated by make test and outputs to the Standard Output.
  • make clean: Deletes all files created by make

To use the MiniJava compiler manually

make
java Main <inputFile1>.java <inputFile2>.java ...

LLVM File Execution

Install clang: sudo apt update && sudo apt install clang

clang -o out1 <inputFile1>.ll
./out1

If the MiniJava compiler type checking is successful, it will output the field and method offsets for each class in the Standard Output.
