There was a problem hiding this comment.
Typo in description:
Converts existing resource attributes [[hlsl::resource_class(..)]] and [[is_rov]]
tofrom declaration attributes to type attributes.
There's many places in the existing tests where these attributes are being used in ways we don't really intend them to use. Maybe now would be the right time to fix them up?
- use __hlsl_resource_t in tests - move function out of SemaHLSL - call erase with iterator

Converts existing resource attributes
[[hlsl::resource_class(..)]]and[[is_rov]]from declaration attributes to type attributes.During type attribute processing all HLSL resource type attributes are validated and collected by
SemaHLSL(SemaHLSL::handleResourceTypeAttr). At the end of the declaration they are be combined into a singleHLSLAttributedResourceTypeinstance (SemaHLSL::ProcessResourceTypeAttributes) that wraps the original type and stores all of the necessary information about the resource.SemaHLSLwill also need to short-term-store theTypeLocinformation for the newly created type that will be grabbed byTypeSpecLocFillersoon after it is created.Updates all places that expected resource attributes on declarations like resource binding diagnostic, builtin types in HLSLExternalSemaSource, or codegen.
Also includes implementation of
TreeTransform<Derived>::TransformHLSLAttributedResourceTypethat enables the use of attributed resource types inside templates.Fixes #104861
