MLIR Python Bindings

MLIR Python Bindings

MLIR Python Bindings is a project of Google Summer of Code 2020.

Getting the Source Code and Building Python Bindings

This is the work-flow and configuration to get and build MLIR Python Bindings:

1. Clone llvm-project (The MLIR Python Bindings project is based on the LLVM system. ):

   • git clone [email protected]:llvm/llvm-project.git

   Clone the mlir-python-bindings in the specific directory:

   • cd llvm-project/mlir

   • git clone [email protected]:zhanghb97/mlir-python-bindings.git bindings

   Modify the CMakeLists.txt

   • Append add_subdirectory(bindings) to llvm-project/mlir/CMakeLists.txt

2. Configure and build MLIR and mlir-python-bindings:

   • cd llvm-project

   • mkdir <build directory name> (e.g. mkdir build)

   • cd <build directory name> (e.g. cd build)

   • Configure the project:

     cmake -G Ninja ../llvm \
       -DLLVM_ENABLE_PROJECTS=mlir\
       -DLLVM_TARGETS_TO_BUILD="host"\
       -DCMAKE_BUILD_TYPE=Release\
       -DLLVM_BUILD_LLVM_DYLIB=ON\
       -DLLVM_LINK_LLVM_DYLIB=ON
     

     You can generate the shared library mlir.so wherever you want with the option -DMLIR_LIBRARY_PATH. For example:

     -DMLIR_LIBRARY_PATH=~/llvm-project/build/bin/
     

     Otherwise, the shared library will be generated to llvm-project/<build directory name>/lib by default.

   • cmake --build . --target check-mlir-python
