By John Potz and Alex Gravenor for CSC431 at Cal Poly in Spring 2019

Dependencies

• Clang version 6.0.0
• arm-linux-gnueabi-gcc verion 7.4.0
• JRE version 9 or higher
• ANTLR

Or

• Docker

Flags

• -llvm (emit llvm, the default is arm)
• -compile (compile the output assembly / llvm)
• -dead-code (-dc) (Eliminate dead code)
• -constant-prop (-cp) (Propogate constants)
• -simplify-cfg (-sc) (Simplify the Control Flow Graph)

How to Use

./run.sh source_file.mini [-compile] [-llvm] [-dead-code] [-constant-prop] [-simplify-cfg]

The output will be to source_file.ll, source_file.s and source_file.

If you compile to assembly, it creates an ARM32 elf executable.
