This compiler converts LLVM IR to SWPP assembly.

Bug fixes:
- Apr. 30: Compilation error fix
- May. 1: Copy should emit bitwidth, SExt should correctly emit mask, PHI is incorrectly emitted when used by each other
- May. 3: Support global variables (SimpleBackend.cpp will lower them to
malloc+inttoptr <glb var address>), switch should print dot at basic block names - May. 7: Fix crash when a constant is given as a branch condition or an undef value is used, let global var allocation only happen at main
To compile this project, you'll need to clone & build LLVM 10.0 first. Please follow README.md from https://github.com/aqjune/llvmscript using llvm-10.0.json. If you did assignment 4 or 5, you will already have built this.
After LLVM 10.0 is successfully built, please run:
./configure.sh <LLVM bin dir (ex: ~/llvm-10.0-releaseassert/bin)>
make
To run tests including FileCheck and Google Test:
make test
Compile LLVM IR input.ll into an assembly a.s using this command:
./sf-compiler input.ll -o a.s
To see the IR that has registers depromoted before emitting assembly, please run:
./sf-compiler input.ll -o a.s -print-depromoted-module
