* spirv: add support for ops added by multiple extensions Some spirv ops are added by multiple extensions and capabilities. This commit adds support to avoid emitting unnecessary extensions and capabilities if one of the options is already required by some other op. * spirv: allow OpRaytracingAccelerationStructure to use multiple extensions This Op is provided by both SPV_KHR_ray_tracing and SPV_KHR_ray_query and the respective capabilities. Use one if already available and otherwise fall back to SPV_KHR_ray_tracing. * tests/vkray: add negative checks for RayTracingKHR and RayQueryKHR - Add new rayquery-compute.slang to test that only RayQueryKHR is needed in compute shaders. - Add checks for RayTracingKHR and RayQueryKHR capabilities and extensions in raygen.slang --------- Co-authored-by: Ellie Hermaszewska <ellieh@nvidia.com>
* Don't load cached builtin module in slang-bootstrap. * Fixes. * format code --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>
… CMake (shader-slang#6675) * Improve embed tool to search all include directories as determined by CMake Hopefully this puts an end to prelude generation issues. * Update CMakeLists.txt * Update CMakeLists.txt * Use Slang's string representation instead of malloc-ing chars
Close shader-slang#6541. Previously in type legalization pass, we skip the VoidType field when call make_struct, however in some optimization pass we keep counting the VoidType field. We have to make this behavior consistently over all our codebase. So in this change, we spot the make_struct call and leave VoidType field as it.
* Fix mul operator followed by global scope
This should fix expr like `2.0f * ::a::b::c`.
But it will no longer parse something like
```
extension<T> Ptr<T> { static void foo(); }
int*::foo() // won't work, but this is a less common case
```
Fixes shader-slang#6684
* Update simpe-namespace.slang to test global scope
…ng#6687) * Fix SPV_KHR_maximal_reconvergence extension name spelling Vulkan validation layers emit warnings on lowercase khr. * Move OpExtension check
* Eliminate empty struct on metal target Close 6573. We previously disabled the type legalization for ParameterBlock on Metal, but Metal doesn't allow empty struct in the argument buffer which is mapped from ParameterBlock, so we will need legalizeEmptyTypes on Metal target. * update test * update function name
…#6695) close shader-slang#6694 We should return nullptr when findAndValidateEntryPoint fails to valid the entrypoint.
* Ignore failure to fetch webgpu_dawn and slang-tint Fixes shader-slang#6683 * format code --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>
