Building hipify-clang

Building hipify-clang#

After cloning the HIPIFY repository (git clone https://github.com/ROCm/HIPIFY.git), run the following commands from the HIPIFY root folder.

cd .. \
mkdir build dist \
cd build

cmake \
-DCMAKE_INSTALL_PREFIX=../dist \
-DCMAKE_BUILD_TYPE=Release \
../hipify

make -j install

To ensure LLVM is found, or in case of multiple LLVM instances, specify the path to the root folder containing the LLVM distribution:

-DCMAKE_PREFIX_PATH=/usr/llvm/20.1.8/dist

On Windows, specify the following option for CMake: -G "Visual Studio 17 2022"

Build the generated hipify-clang.sln using Visual Studio 17 2022 instead of Make. See Windows testing for the supported tools for building.

As debug build type -DCMAKE_BUILD_TYPE=Debug is supported and tested, it is recommended to build LLVM+Clang in debug mode.

Also, 64-bit build mode (-Thost=x64 on Windows) is supported, hence it is recommended to build LLVM+Clang in 64-bit mode.

You can find the binary at ./dist/hipify-clang or at the folder specified by the -DCMAKE_INSTALL_PREFIX option.

Testing hipify-clang#

hipify-clang is equipped with unit tests using LLVM lit or FileCheck.

Build LLVM+Clang from sources, as prebuilt binaries are not exhaustive for testing. Before building, ensure that the software required for building belongs to an appropriate version.

LLVM >= 10.0.0#

  1. Download LLVM project sources.

  2. Build LLVM project:

    cd .. \
mkdir build dist \
cd build

    Linux:

    cmake \
  -DCMAKE_INSTALL_PREFIX=../dist \
  -DLLVM_TARGETS_TO_BUILD="X86" \
  -DLLVM_ENABLE_PROJECTS="clang" \
  -DLLVM_INCLUDE_TESTS=OFF \
  -DCMAKE_BUILD_TYPE=Release \
  ../llvm-project/llvm
make -j install

    Windows:

    cmake \
  -G "Visual Studio 17 2022" \
  -A x64 \
  -Thost=x64 \
  -DCMAKE_INSTALL_PREFIX=../dist \
  -DLLVM_TARGETS_TO_BUILD="" \
  -DLLVM_ENABLE_PROJECTS="clang" \
  -DLLVM_INCLUDE_TESTS=OFF \
  -DCMAKE_BUILD_TYPE=Release \
  ../llvm-project/llvm

    Run Visual Studio 17 2022, open the generated LLVM.sln, build all, and build project INSTALL.

  3. Install CUDA version 7.0 or greater.

    • In case of multiple CUDA installations, specify the particular version using DCUDA_TOOLKIT_ROOT_DIR option:

      Linux:

      -DCUDA_TOOLKIT_ROOT_DIR=/usr/include

      Windows:

      -DCUDA_TOOLKIT_ROOT_DIR="C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v12.8"

-DCUDA_SDK_ROOT_DIR="C:/ProgramData/NVIDIA Corporation/CUDA Samples/v12.8"

  4. [Optional] Install cuTensor:

    • To specify the path to cuTensor, use the CUDA_TENSOR_ROOT_DIR option:

      Linux:

      -DCUDA_TENSOR_ROOT_DIR=/usr/include

      Windows:

      -DCUDA_TENSOR_ROOT_DIR=D:/CUDA/cuTensor/2.2.0.0

  5. [Optional] Install cuDNN belonging to the version corresponding to the CUDA version:

    • To specify the path to cuDNN, use the CUDA_DNN_ROOT_DIR option:

      Linux:

      -DCUDA_DNN_ROOT_DIR=/usr/include

      Windows:

      -DCUDA_DNN_ROOT_DIR=D:/CUDA/cuDNN/9.11.0

  6. [Optional] Install CUB 1.9.8 for CUDA < 11.0 only; for CUDA >= 11.0, the CUB shipped with CUDA will be used for testing.

    • To specify the path to CUB, use the CUDA_CUB_ROOT_DIR option (only for CUDA < 11.0):

      Linux:

      -DCUDA_CUB_ROOT_DIR=/srv/git/CUB

      Windows:

      -DCUDA_CUB_ROOT_DIR=D:/CUDA/CUB

  7. Install Python version 3.0 or greater.

  8. Install lit and FileCheck; these are distributed with LLVM.

    • Install lit into Python:

      Linux:

      python /usr/llvm/20.1.8/llvm-project/llvm/utils/lit/setup.py install

      Windows:

      python D:/LLVM/20.1.8/llvm-project/llvm/utils/lit/setup.py install

      In case of errors similar to ModuleNotFoundError: No module named 'setuptools', upgrade the setuptools package:

      python -m pip install --upgrade pip setuptools

    • Starting with LLVM 6.0.1, specify the path to the llvm-lit Python script using the LLVM_EXTERNAL_LIT option:

      Linux:

      -DLLVM_EXTERNAL_LIT=/usr/llvm/20.1.8/build/bin/llvm-lit

      Windows:

      -DLLVM_EXTERNAL_LIT=D:/LLVM/20.1.8/build/Release/bin/llvm-lit.py

    • FileCheck:

      Linux:

      Copy from /usr/llvm/20.1.8/build/bin/ to CMAKE_INSTALL_PREFIX/dist/bin.

      Windows:

      Copy from D:/LLVM/20.1.8/build/Release/bin to CMAKE_INSTALL_PREFIX/dist/bin.

      Alternatively, specify the path to FileCheck in the CMAKE_INSTALL_PREFIX option.

  9. To run OpenGL tests successfully on:

    Linux:

    Install GL headers.

    On Ubuntu, use: sudo apt-get install mesa-common-dev

    Windows:

    No installation required. All the required headers are shipped with the Windows SDK.

  10. Set the HIPIFY_CLANG_TESTS option to ON: -DHIPIFY_CLANG_TESTS=ON

  11. Build and run tests.

LLVM <= 9.0.1#

  1. Download LLVM + Clang sources

  2. Build LLVM+Clang:

    cd .. \
mkdir build dist \
cd build

    Linux:

    cmake \
  -DCMAKE_INSTALL_PREFIX=../dist \
  -DLLVM_SOURCE_DIR=../llvm \
  -DLLVM_TARGETS_TO_BUILD="X86" \
  -DLLVM_INCLUDE_TESTS=OFF \
  -DCMAKE_BUILD_TYPE=Release \
  ../llvm
make -j install

    Windows:

    cmake \
  -G "Visual Studio 16 2019" \
  -A x64 \
  -Thost=x64 \
  -DCMAKE_INSTALL_PREFIX=../dist \
  -DLLVM_SOURCE_DIR=../llvm \
  -DLLVM_TARGETS_TO_BUILD="" \
  -DLLVM_INCLUDE_TESTS=OFF \
  -DCMAKE_BUILD_TYPE=Release \
  ../llvm

  3. Run Visual Studio 16 2019, open the generated LLVM.sln, build all, and build the INSTALL project.

5 LLVM 14.x.x is the latest major release supporting Visual Studio 2017.

To build LLVM 14.x.x correctly using Visual Studio 2017, add -DLLVM_FORCE_USE_OLD_TOOLCHAIN=ON to corresponding CMake command line.

You can also build LLVM < 14.x.x correctly using Visual Studio 2017 without the LLVM_FORCE_USE_OLD_TOOLCHAIN option.

6 Note that LLVM 17.0.0 was withdrawn due to an issue; use 17.0.1 or newer instead.

7 Note that LLVM 18.0.0 has never been released; use 18.1.0 or newer instead.
