[ASAN] Use after free memory problem when merging geps

@tcorringham Related to comment about a fix for this issue [here](https://github.com/microsoft/DirectXShaderCompiler/issues/6223#issuecomment-1946924428): I think the correct fix for this is not to call `MergeGepUse` inside of `ReplaceUsesForLoweredUDT`. If merging is required,...

[Feature Request] Validator should prevent AllocateRayQuery handles from being used as anything but handles

We should iterate users of AllocateRayQuery and reject any that aren't PHI, Select, or a RayQuery intrinsic at the appropriate handle argument.

wgf11shader5x: Index\Samplers & Index\ConstantBuffers convert error in dxbcconv.dll that dynamic index only support Interface

As it turns out, the ID3D11Interface functionality is the only way to officially use dynamic resource indexing before SM 5.1 (FXC disallows explicit dynamic indexing in SM 5.0).  The assembly-based...

Accessing "aggressively packed" array elements in a constant buffer via static cast results in ICE

The problem is rooted in the use of `static` for the local variables. This is unnecessary, and it sets up a flag to track first entry into function predicating the...

Should emit error on unsupported cast operator overloading that's silently ignored

Related to #4096.

SM6.7 MSAA UAVs only include sample count info in the DXIL in annotateHandle instruction args

The annotate handle was meant to be a replacement for the metadata for the driver, but never quite got that far. I believe the issue is one of restoring global...

SM6.7 MSAA UAVs only include sample count info in the DXIL in annotateHandle instruction args

This is something we could add in a future DXIL version, which might be a solution to your scenario. If it's added in a future version, you could add it...

SM6.7 MSAA UAVs only include sample count info in the DXIL in annotateHandle instruction args

> [@jenatali](https://github.com/jenatali), [@tex3d](https://github.com/tex3d), [@bogner](https://github.com/bogner) - are we at all likely to consider this important to do before SM 7.0? If not, is there any reason to keep this issue open...

DXR 1.1: Using TraceRayInline(...) right after TraceRay(...) crashes shader compilation

Thanks for the report! This bug can be worked around if you use a different RayDesc structure instance for your TraceRayInline than you do for TraceRay. You can always assign...

Support IMul/UMul/UDiv with two outputs from HLSL

@llvm-beanz > we don’t have any tests for them at runtime The shader5x HLK test does test these operations for D3D11, and we test them in DXIL by running that...
