This project aims to provide translation of DXIL (SM 6.x) shaders to SPIR-V which can be used in the vkd3d project, which implements D3D12 on top of Vulkan.
Check out submodules first with git submodule update --init.
No external dependencies apart from the submodules are required to build.
This project implements a "small" LLVM C++ API subset which acts as a drop-in replacement for the full LLVM.
It is possible to build against the true LLVM C++ API if llvm is checked out in external/llvm and -DDXIL_SPIRV_NATIVE_LLVM=ON CMake option is used.
See checkout_llvm.sh script.
Standard CMake build.
mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
make
make install
Only the C API is installed and is expected to be kept ABI/API stable when it releases.
pkg-config dxil-spirv-c-shared --cflags --libs
Something like:
find_package(dxil_spirv_c_shared)
if (dxil_spirv_c_shared_FOUND)
message("Found dxil-spirv! Enabling DXIL support.")
target_link_libraries(vkd3d-shader PRIVATE dxil-spirv-c-shared)
target_compile_definitions(vkd3d-shader PRIVATE HAVE_DXIL_SPV)
target_sources(vkd3d-shader PRIVATE vkd3d/libs/vkd3d-shader/dxil.c)
else()
message("Did not find dxil-spirv :( Disabling DXIL support.")
endif()
The primary method of testing dxil-spirv and avoiding regressions is through a reference shader suite.
First, build DXC. To keep output consistent, we must use a fixed version of DXC. Currently, this only works on Linux, the Windows build of DXC does not seem to support CMake properly.
./checkout_dxc.sh
./build_dxc.sh
The test suite accepts an arbitrary path to DXC, so if you have a standalone binary somewhere, that can work as well.
When adding new tests, place the HLSL test in shaders/ somewhere and run:
./test_shaders.py shaders --dxc external/dxc-build/bin/dxc --dxil-spirv cmake-build-debug/dxil-spirv
If there is any mismatch, the test script will complain. If there are legitimate changes to be made,
add --update to the command. The updated files should now be committed alongside the dxil-spirv change.
