`*` Download the patch and unpack it into your LLVM distributive directory; a few header files will be overwritten; rebuilding of LLVM is not needed.

In most cases, you can get a suitable version of LLVM+CLANG with your package manager.

Failing that or having multiple versions of LLVM, you can [download a release archive](http://releases.llvm.org/), build or install it, and set
[CMAKE_PREFIX_PATH](https://cmake.org/cmake/help/v3.12/variable/CMAKE_PREFIX_PATH.html) so `cmake` can find it; for instance: `-DCMAKE_PREFIX_PATH=f:\LLVM\6.0.1\dist`

## <a name="build-and-install"></a> Build and install

### <a name="building"></a> Build

Assuming this repository is at `./HIP`:

```shell
cd hipify-clang
mkdir build dist
cd build

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

make -j install
```
On Windows, the following option should be specified for `cmake` at first place: `-G "Visual Studio 15 2017 Win64"`; the generated `hipify-clang.sln` should be built by `Visual Studio 15 2017` instead of `make.`

Debug build type `-DCMAKE_BUILD_TYPE=Debug` is also supported and tested; `LLVM+CLANG` should be built in `Debug` mode as well.
64-bit build mode `-Thost=x64` is supported as well; `LLVM+CLANG` should be built in 64-bit mode as well.

The binary can then be found at `./dist/bin/hipify-clang`.

### <a name="testing"></a> Testing

`hipify-clang` has unit tests using LLVM [`lit`](https://llvm.org/docs/CommandGuide/lit.html)/[`FileCheck`](https://llvm.org/docs/CommandGuide/FileCheck.html).

**LLVM+CLANG should be built from sources, pre-built binaries are not exhaustive for testing.**

To run it:
1. Download [`LLVM`](http://releases.llvm.org/6.0.1/llvm-6.0.1.src.tar.xz)+[`CLANG`](http://releases.llvm.org/6.0.1/cfe-6.0.1.src.tar.xz) sources.
2. Build [`LLVM+CLANG`](http://llvm.org/docs/CMake.html):
   ```shell
   cd llvm
   mkdir build dist
   cd build
   ```

     - **Linux**:
   ```shell
        cmake \
         -DCMAKE_INSTALL_PREFIX=../dist \
         -DLLVM_SOURCE_DIR=../llvm \
         -DCMAKE_BUILD_TYPE=Release \
         ../llvm
        make -j install
   ```

     - **Windows**:
   ```shell
        cmake \
         -G "Visual Studio 15 2017 Win64" \
         -DCMAKE_INSTALL_PREFIX=../dist \
         -DLLVM_SOURCE_DIR=../llvm \
         -DCMAKE_BUILD_TYPE=Release \
         -Thost=x64 \
         ../llvm
   ```

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Run `Visual Studio 15 2017`, open the generated `LLVM.sln`, build all, build project `INSTALL`.


3. Ensure [`CUDA`](https://developer.nvidia.com/cuda-toolkit-archive) of minimum version 7.0 is installed.

    * Having multiple CUDA installations to choose a particular version the `DCUDA_TOOLKIT_ROOT_DIR` option should be specified:

        - Linux: `-DCUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda-10.0`

        - Windows: `-DCUDA_TOOLKIT_ROOT_DIR="c:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v9.0"`

          `-DCUDA_SDK_ROOT_DIR="c:/ProgramData/NVIDIA Corporation/CUDA Samples/v9.0"`

4. Ensure [`cuDNN`](https://developer.nvidia.com/rdp/cudnn-archive) of the version corresponding to CUDA's version is installed.

    * Path to cuDNN should be specified by the `CUDA_DNN_ROOT_DIR` option:

        - Linux: `-DCUDA_DNN_ROOT_DIR=/srv/CUDNN/cudnn-10.0-v7.6.0.64`

        - Windows: `-DCUDA_DNN_ROOT_DIR=f:/CUDNN/cudnn-9.0-windows10-x64-v7.6.0.64`

5. Ensure [`python`](https://www.python.org/downloads) of minimum required version 2.7 is installed.

6. Ensure `lit` and `FileCheck` are installed - these are distributed with LLVM.

    * Install `lit` into `python`:

        - Linux: `python /srv/git/LLVM/8.0.0/llvm/utils/lit/setup.py install`

        - Windows: `python f:/LLVM/6.0.1/llvm/utils/lit/setup.py install`

    * Starting with LLVM 6.0.1 path to `llvm-lit` python script should be specified by the `LLVM_EXTERNAL_LIT` option:

        - Linux: `-DLLVM_EXTERNAL_LIT=/srv/git/LLVM/8.0.0/build/bin/llvm-lit`

        - Windows: `-DLLVM_EXTERNAL_LIT=f:/LLVM/6.0.1/build/Release/bin/llvm-lit.py`

7. Set `HIPIFY_CLANG_TESTS` option turned on: `-DHIPIFY_CLANG_TESTS=1`.

8. Run `cmake`:
     * [Linux](#linux)
     * [Windows](#windows)

9. Run tests:

     - Linux: `make test-hipify`.

     - Windows: run `Visual Studio 15 2017`, open the generated `hipify-clang.sln`, build project `test-hipify`.

### <a name="linux"></a >Linux

On Linux the following configurations are tested:

Ubuntu 14: LLVM 5.0.0 - 6.0.1, CUDA 7.0 - 9.0, cudnn-5.0.5 - cudnn-7.6.0.64

Ubuntu 16-18: LLVM 8.0.0, CUDA 8.0 - 10.0, cudnn-5.1.10 - cudnn-7.6.0.64

Build system for the above configurations:

## <a name="running-and-using-hipify-clang"></a> Running and using hipify-clang

To process a file, `hipify-clang` needs access to the same headers that would be needed to compile it with clang.

For example:

```shell
./hipify-clang square.cu --cuda-path=/usr/local/cuda-10.0 -I /usr/local/cuda-10.0/samples/common/inc
```

`hipify-clang` arguments are given first, followed by a separator, and then the arguments you'd pass to `clang` if you
were compiling the input file. The [Clang manual for compiling CUDA](https://llvm.org/docs/CompileCudaWithLLVM.html#compiling-cuda-code)
may be useful.

For a list of `hipify-clang` options, run `hipify-clang --help`.
