Support cooperative vector including Vulkan-Header (#6228)

2025-01-30T21:19:13+00:00

* Support cooperative vector including Vulkan-Header Adding a Slang support for cooperative vector with vulkan-header update.

Change how DeclRef::toText works (#5592)

2024-11-21T01:51:59+00:00

* Change how DeclRef::toText works We now ignore the decl-ref heirarchy since that only includes nodes with specialization info & simply walk up the tree of decls, while emitting any specializations present in the decl-ref. * Update some tests. Add cases for direct refs to generic params & Lookup decl refs

Vulkan update/NVAPI support (#1511)

2020-08-21T20:04:42+00:00

* First pass at incorporating nvapi into test harness. * D3d12 Atomic Float Add via NVAPI working * Dx12 atomic float appears to work. * Atomic float add on Dx12. * Added atomic64 feature addition to vk. Fix correct output for atomic-float-byte-address.slang * Disable atomic float failing tests. * Upgraded VK headers. * Detect atomic float availability on VK. * Try to get test working for in64 atomic. * Made HLSL prelude controlled via the render-test requirements. * Added -enable-nvapi to premake. * Fix D3D12Renderer when NVAPI is not available. * Small improvements to VKRenderer. * Improve atomic documentation in target-compatibility.md.

Initial work on getting render-test to support vulkan (#391)

2018-02-02T15:49:32+00:00

* Basic fixes to gets some Vulkan GLSL out of the IR path We haven't been paying much attention to the Vulkan output from the IR path, but that needs to change ASAP. This commit really just implements quick fixes, without concern for whether they are a good fit in the long term. - Add some more mappings from D3D `SV_*` semantics to built-in GLSL variables, and stop redeclaring those built-in variables in our output GLSL. - Add custom output logic for HLSL `*StructuredBuffer` types, so that they emit as `buffer` declarations with an unsized array inside. This has some real limitations: - What if the user passes the type into a function? The parameter should be typed as an (unsized) array, and not a buffer. - What happens if we have an array of structured buffers? We need to declare an array of blocks (which GLSL allows), but this changes the GLSL we should emit when indexing. - Customize the way that we emit entry point attributes (e.g., `[numthread(...)]`) to also support outputting equivalent GLSL `layout` qualifiers. In many of these cases, a better fix might involve doing more of this work in the IR as part of legalization (e.g., we already have a pass that deals with varying input/output for GLSL, so that should probalby be responsible for swapping the `SV_*` to `gl_*`, especially in cases where the types don't match perfectly across langauges). * Start adding Vulkan support to render-test - Add both Vulkan and D3D12 as nominally supported back-ends - Add a git submodule to pull in the Vulkan SDK dependencies - I don't want our users to have to install it manually, since the SDK is huge - Checking in the binaries to our main repository seems like a bad idea, but my hope is that we can prune the bloat using a subodule with the `shallow` cloning option - Implement enough logic for the Vulkan back-end to get a single test passing on Vulkan * Fix warning * Fixup: disable new compute tests for Linux * Fixup: ignore Vulkan tests on AppVeyor * Dynamically load Vulkan implementation Rather than statically link to the Vulkan library, we will dynamically load all of the required functions. This removes the need to have the stub libs involved at all. * Remove vulkan submodule I had set up a `vulkan` submodule to pull in the headers and stub libs, but now that we are going to dynamically load all the symbols anyway, the stub lib binaries aren't needed and we can just commit the headers. * Add Vulkan headers to external/
