GetAttributeAtVertex() doesn't work on function parameters

2

**Description** When using an array member of a VS interpolant structure, `GetAttributeAtVertex` fails to compile. **Steps to Reproduce** ```hlsl // dxc.exe repro.hlsl /Tps_6_1 /EMainPS cbuffer Globals : register (b0) {...

Make ID3D12GraphicsCommandList::SetDescriptorHeaps take ManuallyDrop'd references

### Suggestion IIRC, most D3D12 structs that hold references to other D3D objects take these via `ManuallyDrop`. eg: ```rust } #[repr(C)] pub struct D3D12_BUFFER_BARRIER { pub SyncBefore: D3D12_BARRIER_SYNC, pub SyncAfter:...

We need to ensure that DXC works on ARM64 and would like to catch ARM64 issues as early as possible. Currently, each PR is validated with a variety of platforms...

Developers would like to be able to use reflection data to determine what WaveSizeRange was specified in the shader. Currently this is possible by scanning DXIL, HLSL source or some...

**Description** ``` StructuredBuffer foo : FOO(123); void main() {} // unneeded ``` This crashes on latest dxc.

The proposed schedule for this release is: * [x] 5/8/2024 - Create the release branch from `main` * [x] 5/15/2024 - Release Candidate 1 (begin Ask Mode[^1] for release branch)....

Shader compiler doesn't generate a loop where one should exist

Attributes read via `GetAttributeAtVertex` aren't counted as read in the signature

**Description** ```c++ float4 VCMain( nointerpolation float4 Color:COLOR0) : SV_TARGET0 { #ifdef USE_GET_ATTRIBUTE_AT_VERTEX return GetAttributeAtVertex(Color,0); #endif return Color; } ``` **Steps to Reproduce** With above shader the generated assembly shows the...
