Setup

LLVM

Bundled

This builds and installs a debug version of LLVM in external/install, which is necessary for debugging code generation and using ASAN and UBSAN in the overall project.

cd external
./setup_deps.sh
cd ..

Linux System Install

System install of LLVM 6.0.x is required

MacOS System Install

Apple's bundled LLVM is incomplete, use homebrew:

brew install llvm
echo 'export PATH="/usr/local/opt/llvm/bin:$PATH"' >> ~/.bashrc
export PATH="/usr/local/opt/llvm/bin:$PATH"

Build

Use bundled LLVM:

make

Use system LLVM:

make SYSTEMLLVM=1

Optimized Build:

make SYSTEMLLVM=1 SIMOPT=1
