Error if super-type capabilities are a super-set of sub-type (#7452)

2025-08-08T20:19:25+00:00

Fixes: #7410 Changes: 1. super-type capabilities must be a super-set of sub-type capabilities (and support the same shader stages/targets) * InheritanceDecl visits super-type to inherit it's capabilities; validate InheritanceDecl capabilities against sub-type * visit all container decl's with a default case * clean up functionDeclBase visitor * Simplify `diagnoseUndeclaredCapability` by moving logic into capability checking (more correct*) 3. added changed behavior to documentation 4. fixed some incorrect capabilities 5. **we do not** diagnose capability errors on interface requirement-to-implementation if both lack explicit capability requirements. This change is to work around a slangpy regression (test case for the failing situation is in `tests\language-feature\capability\capability-interface-extension-1.slang`), Note: maybe for slang-2026 we don't do this? 6. requirement & implementation must support the same shader stage/target. This was changed because otherwise we can have cases where `X` inherits from `Y`, but `Y` is only expected to be used in `glsl` whilst `X` is expected to be used in `hlsl | glsl` 7. removed `tests/language-feature/capability/capabilitySimplification3.slang` because it tests nothing special (redundant) Note: not using rebase due to separate branches depending on this PR --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>
