Use symbol alias instead of wrapper synthesis to implement link-time types. (#8603)

2025-10-07T00:21:37+00:00

This change achieves link-time type resolution with a different mechanism. For `extern struct Foo : IFoo = FooImpl;`, instead of synthesizing a wrapper type `Foo` that has a `FooImpl inner` field and dispatches all interface method calls to `inner.method()`, this PR completely removes this synthesis step, and instead just lower such `extern`/`export` types as `IRSymbolAlias` instructions that is just a reference to the type being wrapped. Then we extend the linker logic to clone the referenced symbol instead of the SymbolAlias insts itself during linking. By doing so, we greatly simply the logic need to support link-time types, and achieves higher robustness by not having to deal with many AST synthesis scenarios. Closes #8554. --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>

Relax restriction on using link-time types for shader parameters. (#8387)

2025-09-06T05:37:34+00:00

This change relaxes a previous restriction on link-time types and constants, so that we now allow them to be used to define shader parameters. Doing so will result in a parameter layout that is incomplete prior to linking. The PR added a test to call the reflection API on a fully linked program and ensure that we can report correct binding info.
