PIX: stabilize block enumeration order for PIX's instruction numbering pass.

1

PIX has a pass that adds "instruction ordinals" in order to have a common communication mechanism between, e.g., shader debugging instrumentation and the PIX UI. Unfortunately, the enumeration order of...

PIX: Emit correct input sig elements and view ID state into PSV0 when input sigs are changed by debug instrumentation

2

Three intertwined issues: 1: The shader-debug-instrumentation and pixel-hit-counter passes add SV_VertexId+SV_InstanceId to the input sig for a VS if they are not present, and SV_Position for the PS. The changes...

PIX: Some shader debug pass cleanup in response to CR comments (DXASSERT usage, null check localization, telescoping two terminator cases)

1

These changes are in response to comments on a cherry-pick PR in which it wasn't appropriate to address the issues immediately. The PR in question is: https://github.com/microsoft/DirectXShaderCompiler/pull/6300 fixes #6308 (file...

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

1

**Is your feature request related to a problem? Please describe.** A PIX customer had a shader in which an AllocateRayQuery handle (which is actually typed as i32) was included as...

**Description** Code issue noted in cherry-pick review: https://github.com/microsoft/DirectXShaderCompiler/pull/6300 **Steps to Reproduce** No repro. Code issue. **Actual Behavior** No behavior change expected. **Environment** Not relevant.

Asserts are used in place of DXASSERT in shader debug passes

1

**Description** See [bob80905](https://github.com/bob80905)'s comments on PR https://github.com/microsoft/DirectXShaderCompiler/pull/6300 In summary, "assert" was used when "DXASSERT" is preferred. Plus, some of the asserts are just plain "assert(false)" and could be refactored into...

PIX: Cope with arbitrary <32 integer widths in debugger pass

1

Who knew codegen could generate i25 as part of a switch argument? Not me!

Example: Given this HLSL: ``` static RWByteAddressBuffer DynamicBuffer = ResourceDescriptorHeap[1]; [numthreads(1, 1, 1)] void DynamicResources() { uint val = DynamicBuffer.Load(0u); RWByteAddressBuffer DynamicallyIndexedDynamicBuffer = ResourceDescriptorHeap[256 + val &0xf]; floatRWUAV[0] = DynamicallyIndexedDynamicBuffer.Load(0);...

Attempting to pass a texture in the AS->MS payload struct causes crash

1

**Description** Attempts to compile the following code results in an internal crash in the compiler. (GetLoweredUDT() returns nullptr when passed the payload's type) (This happened while writing tests. Not a...

- a DXIL comment pointing to the original file/line/hlsl snippet ? (rather then having to crawl through metadata) - e.g.: %270 = call float @dx.op.binary.f32(i32 35, float 0x3F1A36E2E0000000, float %269),...
