Steps to build LLVM on macOS and Linux

Configure LLVM

cmake -S llvm -B build -G Ninja -DCMAKE_BUILD_TYPE=Release -DLLVM_PARALLEL_{COMPILE,LINK}_JOBS=4 -DLLVM_ENABLE_PROJECTS="lld" -DLLVM_USE_LINKER=lld -DCMAKE_INSTALL_PREFIX=folder/where/you/want/to/leave/llvm

Build

ninja

Install

ninja install

Remove unnecessary files from installation

Delete:

• All binaries, but llvm-config from folder/where/you/want/to/leave/llvm/bin
• Remove share folder from folder/where/you/want/to/leave/llvm/
• Remove all .so files from folder/where/you/want/to/leave/llvm/lib
• Remove cmake folder from folder/where/you/want/to/leave/llvm/lib

Steps to build LLVM on Windows

Configure LLVM

cmake -S llvm -B build -DLLVM_ENABLE_PROJECTS=lld -DLLVM_TARGETS_TO_BUILD=X86 -Thost=x64 -DLLVM_USE_CRT_RELEASE=MT

Build

To build open the generated LLVM.sln file on build directory with Visual Studio. Select Release and then compile. If you don't have a lot of ram you should limit thee number of cores used in for compilation. For that you can follow this link https://stackoverflow.com/a/49068569.

Install

cmake --install . --prefix folder/where/you/want/to/leave/llvm/
