Without the fix ivars with anonymous types can trigger errors like > error: 'TestClass::structIvar' from module 'Target' is not present in definition of 'TestClass' provided earlier > [...] > note: declaration of 'structIvar' does not match It happens because types of ivars from different modules are considered to be different. And it is caused by not merging anonymous `TagDecl` from different modules. To fix that I've changed `serialization::needsAnonymousDeclarationNumber` to handle anonymous `TagDecl` inside `ObjCInterfaceDecl`. But that's not sufficient as C code inside `ObjCInterfaceDecl` doesn't use interface decl as a decl context but switches to its parent (TranslationUnit in most cases). I'm changing that to make `ObjCContainerDecl` the lexical decl context but keeping the semantic decl context intact. Test "check-dup-decls-inside-objc.m" doesn't reflect a change in functionality but captures the existing behavior to prevent regressions. rdar://85563013 Differential Revision: https://reviews.llvm.org/D118525
