Allan Shortlidge	16de339051	AST: Enable -unavailable-code-optimization for zippered libraries. ... Correct the determination of whether a declaration is unreachable at runtime when compiling a zippered library. Resolves rdar://125930716.	2025-02-09 11:20:48 -08:00
Allan Shortlidge	feba547411	AST: Adopt Decl::isUnreachableAtRuntime() in Hashable/Equatable derivation. ... When deriving `Hashable` and `Equatable` for enums, use `Decl::isUnreachableAtRuntime()` to determine whether or not to insert `_diagnoseUnavailableCodeReached()` traps for specific enum elements. This fixes a bug where inappropriate traps were inserted for enum elements that are unavailable for app extensions. It also fixes a bug where traps were inserted when building a zippered library for macOS and enum elements were unavailable on macOS but not for macCatalyst clients.
