Update slang-rhi deps for gfx-unit-test (#8237)

2025-08-26T18:01:07+00:00

This PR marks the `slang-rhi` a required dependecy for `platform` and `gfx-unit-test`, and only build them when `SLANG_ENABLE_SLANG_RHI=ON`. This should allow the slang still to be built without those tests components when `SLANG_ENABLE_SLANG_RHI=OFF`. --------- Co-authored-by: slangbot Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>

Fix a bug in examples/reflection-api (#7652)

2025-07-08T20:38:32+00:00

The bug here is subtle enough that it was missed during development of the example, and it it unlikely to be hit by typical applications. All that said, it is good to ensure that this example does things correctly, since we are pointing developers to it as an example of how to correctly extract information using the reflection API. In order to get the bug to surface, one can target Vulkan/SPIR-V using input code like: ``` struct Small { float4 v; Texture2D t; } struct Big { float4 u; ConstantBuffer smallCB; ParameterBlock smallPB; } ConstantBuffer bigCB; ``` Without this change, the example would display an incorrect cumulative offset for `bigCB.smallPB.t`. The incorrectly-computed offset showed that the `binding`s consumed by `bigCB.smallCB` (for both its constant buffer and its `t` field) were being included in the offset computed for the `t` within the parameter block (when the outer parameter block should have caused those offsets to be ignored). The underlying bug in the example is that when recursively printing the cumulative offsets for the "container" and "content" part of a buffer/block, the example was including the buffer/block in the `AccessPath` when printing cumulative offsets for the "content" part, but not for the "container" part. The fix is just to shift the order of things and use the same `AccessPath` when printing both the "container" and "content" parts of a buffer/block. It is difficult to be 100% certain that this change is correct, and that there are no corner cases where the new code gives unexpected/wrong results. I have manually tested the example code by throwing a variety of shader parameter declarations at it, and the new logic seems robust. We are probably at the point where the code of this example probably needs to be turned into a stand-alone tool that we can use as part of our automated testing. That will have to wait for a future change; the goal of this change is to just get the simple bug fixe checked in.

Enable Windows full debug testsuite in CI (#7085)

2025-05-16T21:51:46+00:00

* Unify Debug Layer Control Logic and Add Disable Option for Debug Builds This PR refactors and unifies the debug layer control logic in slang-test. A new `-disable-debug-layers` option is introduced, allowing debug builds to skip enabling the validation (debug) layer. This is currently needed to ensure stability in the debug test suite. Previously, different toggles such as ENABLE_VALIDATION_LAYER, ENABLE_DEBUG_LAYER, and debugLayerEnabled were used inconsistently across different components of slang-test. This PR standardizes the logic by using a single variable, debugLayerEnabled, to control the enabling/disabling of the debug layer internally. Notes: By default, the debug/validation layer is enabled in debug builds and is not supported in release builds of slang-test. Fixes: #7132 * Disable spirv-opt for the DebugFunctionDefinition issue * Run debug build only in GCP machines * Fix VUID-vkCmdPipelineBarrier-pBufferMemoryBarriers-02818 dstAcessMask can't include VK_ACCESS_TRANSFER_READ_BIT when stage mask has VK_PIPELINE_STAGE_RAY_TRACING_SHADER_BIT_KHR * Set failed retry limit to 32 --------- Co-authored-by: slangbot Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>
