Use @import rather than @__experimental_modules_import, since the latter is rather a mess to type. llvm-svn: 169919 2012-12-12 06:11:52 +08:00			`@import redecl_merge_left;`
If we end up merging an Objective-C class with an existing Objective-C class that comes from a different module file, make sure that we load all of the pending declarations for the original declaration. llvm-svn: 147168 2011-12-23 03:44:59 +08:00

When deserializing the definition of a C++ class/ObjC class/ObjC protocol, record the definition pointer in the canonical declaration for that entity, and then propagate that definition pointer from the canonical declaration to all other deserialized declarations. This approach works well even when deserializing declarations that didn't know about the original definition, which can occur with modules. A nice bonus from this definition-deserialization approach is that we no longer need update records when a definition is added, because the redeclaration chains ensure that the if any declaration is loaded, the definition will also get loaded. llvm-svn: 148223 2012-01-16 02:08:05 +08:00			`@class ClassWithDef;`
