LLVM fox32

This is a fork of LLVM 22 (development version) with a backend for the fox32 architecture. The goal is translating LLVM IR to fox32 assembly using llc.

For general LLVM information, see README-LLVM.md.

Building

Recommended build invocation:

cmake -S llvm -B build \
  -DCMAKE_BUILD_TYPE=Release \
  -DLLVM_PARALLEL_LINK_JOBS=8 \
  -DCMAKE_CXX_COMPILER_LAUNCHER=ccache \
  -DCMAKE_C_COMPILER_LAUNCHER=ccache

ccache reduces rebuild time. Useful due to frequent iteration.

Then build:

cmake --build build

Usage

Note

The fox32 backend is set as the default triple. You do not need to explicty set it.

Feed LLVM IR to llc:

build/bin/llc input.ll -o output.s

The output is fox32 assembly. As of now you will have to use the fox32 assembler to assemble the output.
