Commands to configure and compile LLVM
$ mkdir debug && cd debug
$ cmake -G Ninja ../llvm \
-DCMAKE_C_COMPILER=clang-12 -DCMAKE_CXX_COMPILER=clang++-12 \
-DLLVM_ENABLE_PROJECTS=mlir -DLLVM_BUILD_EXAMPLES=ON \
-DCMAKE_BUILD_TYPE=Debug \ # change to RelWithDebInfo for release build
-DLLVM_TARGETS_TO_BUILD="X86;NVPTX;AMDGPU" \ # maybe only X86 is needed
-DLLVM_ENABLE_LLD=ON \ # only on Linux
-DLLVM_INSTALL_UTILS=ON \ # optional to install FileCheck and lit
-DCMAKE_INSTALL_PREFIX=$(pwd)/run # install location in `run` under build
$ ninja
$ ninja installThe above installs a debug version of llvm under LLVM_PROJECT/debug/run,
where LLVM_PROJECT is the root of llvm project on your machine.
To compile this project
$ mkdir debug && cd debug
$ cmake -G Ninja .. \
-DMLIR_DIR=/ag/llvm-gh-mlir/debug/run/lib/cmake/mlir \
-DLLVM_DIR=/ag/llvm-gh-mlir/debug/run/lib/cmake/llvm \
-DLLVM_EXTERNAL_LIT=$(which lit) \
-DLLVM_ENABLE_LLD=ON \
-DCMAKE_INSTALL_PREFIX=$(pwd)/run \The above assumes that LLVM_PROJECT=/ag/llvm-gh-mlir, and that lit
command is installed and is globally available
