2012-05-12Only check NSArray/NSDictionary boxing method params once.Jordy Rose
Once we've found a "good" method, we don't need to check its argument types again. (Even if we might have later found a "bad" method, we were already caching the method we first looked up.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@156719 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-12Fix parsing of type-specifier-seq's. Types are syntactically allowed to beRichard Smith
defined here, but not semantically, so new struct S {}; is always ill-formed, even if there is a struct S in scope. We also had a couple of bugs in ParseOptionalTypeSpecifier caused by it being under-loved (due to it only being used in a few places) so merge it into ParseDeclarationSpecifiers with a new DeclSpecContext. To avoid regressing, this required improving ParseDeclarationSpecifiers' diagnostics in some cases. This also required teaching ParseSpecifierQualifierList about constexpr... which incidentally fixes an issue where we'd allow the constexpr specifier in other bad places. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152549 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-07Make parsing of objc @implementations more robust.Argyrios Kyrtzidis
Parsing of @implementations was based on modifying global state from the parser; the logic for late parsing of methods was spread in multiple places making it difficult to have a robust error recovery. -it was difficult to ensure that we don't neglect parsing the lexed methods. -it was difficult to setup the original objc container context for parsing the lexed methods after completing ParseObjCAtImplementationDeclaration and returning to top level context. Enhance parsing of @implementations by centralizing it in Parser::ParseObjCAtImplementationDeclaration(). ParseObjCAtImplementationDeclaration now returns only after an @implementation is fully parsed; all the data and logic for late parsing of methods is now in one place. This allows us to provide code-completion for late parsed methods with mis-matched braces. rdar://10775381 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149987 91177308-0d34-0410-b5e6-96231b3b80d8
