Truncation warning message incorrectly references an invalid hlsl type

1

**Description** Dxc issues a confusing warning when an hlsl intrinsic that returns a 64-bit type is cast to a 32-bit type. **Steps to Reproduce** https://godbolt.org/z/vo84G6nac ``` // dxc /Tvs_6_0 -spirv...

No truncation warning issued for 32-bit output of 64-bit atomics

1

**Description** When using `InterlockedAdd` with a 32-bit output varaible I would expect the compiler to issue a truncation warning, but no warning is given even though the resulting dxil has...

**Description** When loading or storing a matrix to `groupshared` dxc is using an alignment on the instruction that is not guaranteed by the underlying global variable. **Steps to Reproduce** https://godbolt.org/z/9c9os31MW...

Incorrect code for waterfall loop in VS shader

5

If I write a waterfall loop to implement my own version of NonUniformResourceIndex ``` // dxc /Tps_6_0 .\break.hlsl /DOUTPUT=SV_Target // dxc /Tvs_6_0 .\break.hlsl /DOUTPUT=Z StructuredBuffer mainBuf[]: register(t2, space0); [RootSignature("DescriptorTable(SRV(t2, numDescriptors=UNBOUNDED))")]...

dxc moves wave intrisics out of a waterfall loop

1

**Description** The output of a wave intrinsic depends on the current state of which threads are active. When a wave intrinsic occurs in a loop it needs to execute in...

**Description** When using dxc `-link` with an amplification shader target ( `-Tas_6_6`) I get a validation error message: ``` Link failed: error: validation errors Function: main: error: For amplification shader...

DXC does not eliminate wave intrinsic calls even when the result is unused

4

**Description** The wave intrinsics are kept in the final dxil but I would expect them to be removed by DCE. **Steps to Reproduce** https://shader-playground.timjones.io/350a97df5de025ead832c7054409a7aa ``` // dxc /T ps_6_0 t.hlsl...
