Today the Direct3D and HLSL teams are excited to share some insight into the next big step for GPU programmability. Once Shader Model 7 is released, DirectX 12 will accept shaders compiled to SPIR-V™. The HLSL team is committed to open development processes and collaborating with The Khronos® Group and LLVM Project. We’re sharing this information at the beginning of our multi-year development process so that we can be transparent about this transition from the start. We are working with the Khronos SPIR™ and Vulkan® working groups to ensure that this transition benefits the whole development ecosystem.

It is our mission that HLSL be the best language for compiling graphics and compute shaders for any device or GPU runtime API. To support that goal, the HLSL team is actively embracing open technologies and collaborating with industry standards. We will continue to adopt and support the best open-source tools available while contributing our own innovations to make Direct3D and other Microsoft technologies best in class.

In the 8 years since Shader Model 6.0 was first introduced, Direct3D and HLSL have grown considerably in both features and adoption. Releasing DXC on GitHub and the tremendous contributions from open-source collaborators and partners played a significant role in expanding HLSL’s user base to include Vulkan and Metal developers. As a result of this expansion, the team is focusing on developing HLSL support in Clang to enable us to keep up with industry demand for openness and new features. As we look end to end at the best way to support the full spectrum of our users, we are working hard to support HLSL for both DXIL and SPIR-V with Clang and LLVM.
