LLVM to MIPS

Getting Started

Grab the LLVM source

Clone the official LLVM repository from GitHub.

Terminal window
git clone https://github.com/llvm/llvm-project.git

Checkout the LLVM version

Checkout the commit 7602d781b03427052c44537fa4b9c2a6da15697c. You can create a new branch from here.

Terminal window
cd llvm-project
git checkout 7602d781b03427052c44537fa4b9c2a6da15697c
git switch -c your-branch-name

Build the LLVM project. See all options at Building LLVM with CMake. Here is an example: (the Nova target is what we will add, so it won’t work yet)

Nova can be enabled after the Target Triple chapter.

Terminal window
cmake -S llvm -B build -G Ninja \
      -DCMAKE_BUILD_TYPE=Release \
      -DLLVM_BUILD_TESTS=ON \
      -DLLVM_PARALLEL_LINK_JOBS=8 \
      -DLLVM_TARGETS_TO_BUILD='X86;Mips;Nova' # Nova won't work yet


cmake --build build --target llc
