Fix missing link reference to build clspv-opt (#608) Link against LLVMSupport to fix this issue: clspv-opt.dir/main.cpp.o: undefined reference to symbol '_ZTVN4llvm2cl11OptionValueINSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEEEE' libLLVMSupport.so.11git: error adding symbols: DSO missing from command line This only affects shared library builds. Add transitive dependencies as well to ensure check-spirv works out of the box with shared library build. Signed-off-by: Marco Antognini <marco.antognini@arm.com>
Clspv is a prototype compiler for a subset of OpenCL C to Vulkan compute shaders.
It consists of:
Clspv depends on external projects:
Clspv is licensed under the terms of the Apache 2.0 license. The AUTHORS file lists the copyright owners, while individual credit is given in the CONTRIBUTORS file. To contribute, see CONTRIBUTING.md.
Materials in projects Clspv depends on are licensed under their own terms.
Clspv is not an official Google product.
The compiler is an incomplete prototype, with many rough edges.
The input language is a subset of OpenCL C version 1.2. The OpenCL C on Vulkan Specification describes the specific subset, and also the mapping into Vulkan compute shaders.
Compile a set of kernels into a SPIR-V binary module:
clspv foo.cl -o foo.spv
Emit the binary as a C initializer list, for easy embedding of a shader in in a C or C++ program source:
clspv -mfmt=c foo.cl -o -
Predefine some preprocessor symbols:
clspv -DWIDTH=32 -DHEIGHT=64 foo.cl -o foo.spv
Use OpenCL compiler options:
clspv -cl-fast-relaxed-math -cl-single-precision-constant foo.cl -o foo.spv
Show help:
clspv -help
You will need:
Clspv depends on the sources for other projects, at specific commits. Run the following command to download those dependencies, and place them in the third_party
directory:
python3 utils/fetch_sources.py
Then, create a build directory:
cd <clspv-dir> mkdir build cd build
Then configure and build the code:
cmake <clspv-dir> cmake --build .
This will build the clspv
command line compiler and place it in location bin/clspv
under the build directory.
We recommend you use the Ninja build tool if it's available. To do so, replace the last two commands with:
cmake -G Ninja <clspv-dir> ninja
Other useful configuration options (the first cmake
command):
-DCMAKE_BUILD_TYPE=RelWithDebInfo
: Build in release mode, with debugging information. Default is a debug build.See the CMake documentation for more generic options.
To run the test suite from within the build directory:
cmake --build . --target check-spirv
Or if you are using Ninja:
ninja check-spirv
