2011-12-15Keep track of all declarations of an Objective-C class (both forwardDouglas Gregor
declarations and definitions) as ObjCInterfaceDecls within the same redeclaration chain. This new representation matches what we do for C/C++ variables/functions/classes/templates/etc., and makes it possible to answer the query "where are all of the declarations of this class?" git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146679 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-15Modify how the -verify flag works. Currently, the verification string andRichard Trieu
diagnostic message are compared. If either is a substring of the other, then no error is given. This gives rise to an unexpected case: // expect-error{{candidate function has different number of parameters}} will match the following error messages from Clang: candidate function has different number of parameters (expected 1 but has 2) candidate function has different number of parameters It will also match these other error messages: candidate function function has different number of parameters number of parameters This patch will change so that the verification string must be a substring of the diagnostic message before accepting. Also, all the failing tests from this change have been corrected. Some stats from this cleanup: 87 - removed extra spaces around verification strings 70 - wording updates to diagnostics 40 - extra leading or trailing characters (typos, unmatched parens or quotes) 35 - diagnostic level was included (error:, warning:, or note:) 18 - flag name put in the warning (-Wprotocol) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146619 91177308-0d34-0410-b5e6-96231b3b80d8

doesn't duplicate, but they all surface as implicit properties. It's also a useful optimization to not duplicate the implicit getter lookup.
