Doug Gregor	32f577abf2	[Runtime] Perform “deep” comparisons of witness tables when uniquing metadata. ... Metadata uniquing might encounter witness tables that were distinctly generated but come from identical descriptors. Handle this case in metadata uniquing be looking into the protocol conformance descriptors themselves.	2018-11-20 22:07:55 -08:00
Joe Groff	e2dd2ff11f	Runtime: Handle synthesized decl "related entity" tags. ... Clang-importer-synthesized declarations get an extra tag character included in their mangling, which was not being preserved in type context descriptors. This caused runtime lookup for these synthesized types to fail. Fix this by adding the tag information to type context descriptors and teaching the runtime to match it up when fetching metadata by mangled name. Fixes rdar://problem/40878715.	2018-06-28 12:11:12 -07:00
