[SPIR-V] EvaluateAttributeAtSample intrinsic function unimplemented

[nickyc95]

Hi,

I am trying to use the following intrinsic functions in a HLSL shader, which gets converted to SPIRV via DXC.

EvaluateAttributeAtCentroid, EvaluateAttributeAtSample, EvaluateAttributeSnapped

However I get the following error message on compilation:
error: EvaluateAttributeAtSample intrinsic function unimplemented

Are there any plans to implement this?

DXC Version: Compiled locally at revision b0c029e

Thanks,
Nick

I'm running into the same problem with the October 2020 release.

Hi, is there any plan to support this in the future ?
Thanks,

Possible dup of #3649?

[sudonatalie]

Yes, closing as duplicate of #3649 since it has a bit more implementation detail.
