* Back out "Update SPIRV submodules (#5815)"
This backs out commit e50aac13e2c161d672b137a62f6d66820d0f9ff1.
* Use upstream spirv-tools
* Fix bump-glslang.sh for newer versions of spirv-tools
* Use upstream glslang
* Add --do-fetch option to bump glslang
* Bump glslang and friends
Supersedes https://github.com/shader-slang/slang/pull/5815
* Regenerate glslang and spirv-tools outputs
* Fixes to slang-glslang
* Correct spirv intrinsic for OpImageSampleFootprintNV
Note that this currently fails validation with the following error:
```
error: line 145: Result <id> from OpSampledImage instruction must not appear as operand for OpImageSampleFootprintNV, since it is not specified as taking an OpTypeSampledImage. Found result <id> '55[%sampledImage]' as an operand of <id> '56[%resultVal]'.
%sampledImage = OpSampledImage %54 %51 %40
```
This seems to be in error as the spec for
*SPV_NV_shader_image_footprint* states that "Sampled Image must be an
object whose type is OpTypeSampledImage"
https://refined-github-html-preview.kidonng.workers.dev/KhronosGroup/SPIRV-Registry/raw/refs/heads/main/extensions/NV/SPV_NV_shader_image_footprint.html
glslang also seems to fail with the same validation error
* Fix spv storage class test

* Update SPIRV submodules
With the latest SPIR-V submodules, one of tests started failing:
tests/gpu-feature/texture/query/footprint/nv-shader-texture-footprint.slang
[ForceInline] is added to GLSL texture functions in order to inline %true and %false.
Without it, the value was indirectly passed down via a function parameter, which broke the existing test.
Also the test is modified to use -DAG, because the order unpredictably changed for Grad variants due to additional [ForceInline] marks for Gradient functions.
A new validation check in SPIRV-Tools was causing a validation error:
```
error: line 324: [VUID-StandaloneSpirv-OpTypeImage-06924] Cannot store to OpTypeImage, OpTypeSampler, OpTypeSampledImage, or OpTypeAccelerationStructureKHR objects
OpStore %17 %242
```
It appears that this is a bug on SPIRV-Tools.
A proper fix is proposed to Khronos/SPIRV-Tools:
https://github.com/KhronosGroup/SPIRV-Tools/pull/5914
But this commit uses `shader-slang/SPIRV-Tools/fix_for_OpImageSampleFootprintNV` with a custom fix as a temporary solution:
https://github.com/shader-slang/SPIRV-Tools/tree/fix_for_OpImageSampleFootprintNV

'raytracing' and 'texture-footprint' tests
fixed texture-footprint bug
changed when we emit raytracing/rayquery extensions with glsl backend (to reduce incorrect extension emitting)
|

|
|
|
|
|
|
|
| |
* Switch to direct-to-spirv backend as default.
* Fix slang-test.
* Fix.
* Fix.
|
| |
|
|
|
|
|
|
|
| |
* Add SPIRV intrinsics for texture footprint query.
* Cleanup.
