MX-Compiler

A compiler from scratch for Mx*(a c-and-java-like language) to riscv32. Able to generate correct assembly file.

To run the project

./gradlew installDist
./build/install/Compiler/bin/Compiler inputfile

To run codegen tests with llvm or assembly

./gradlew test --tests LLVMTest
./gradlew test --tests CodegenTest

More command line options:

Current Objectives

• Optimizations
  • Graph simplification (edge splitter & preheader)
  • Inst Combine
  • Strength Reduction
  • Induction Variable Recognition
• Some non-trivial optimizations
• Improve code quality in code generation and IR
