2009-03-09Fix PR3766, a really nasty silent miscompilation case where we emittedChris Lattner
a warning and then threw away the AST. While I'm in there, tighten up the code to actually reject completely bogus cases (sending a message to a struct). We still allow sending a message to an int, which doesn't make sense but GCC allows it and is easy to support. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66468 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-22Contains the following (related to problems found while investigting ↵Steve Naroff
<rdar://problem/6497631> Message lookup is sometimes different than gcc's). - Implement instance/class overloading in ObjCContainerDecl (removing a FIXME). This involved hacking NamedDecl::declarationReplaces(), which took awhile to figure out (didn't realize replace was the default). - Changed Sema::ActOnInstanceMessage() to remove redundant warnings when dealing with protocols. For now, I've omitted the "protocol" term in the diagnostic. It simplifies the code flow and wan't always 100% accurate (e.g. "Foo<Prot>" looks in the class interface, not just the protocol). - Changed several test cases to jive with the above changes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65292 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-21This fixes <rdar://problem/6497650> More type mismatches issues with clang.Steve Naroff
Move two key ObjC typechecks from Sema::CheckPointerTypesForAssignment() to ASTContext::mergeTypes(). This allows us to take advantage of the recursion in ASTContext::mergeTypes(), removing some bogus warnings. This test case I've added includes an example where we still warn (and GCC doesn't). Need to talk with folks and decide what to do. At this point, the major bogosities should be fixed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65231 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-18Downgrade complaints about calling unavailable functions to a warningDouglas Gregor
(as GCC does), except when we've performed overload resolution and found an unavailable function: in this case, we actually error. Merge the checking of unavailable functions with the checking for deprecated functions. This unifies a bit of code, and makes sure that we're checking for unavailable functions in the right places. Also, this check can cause an error. We may, eventually, want an option to make "unavailable" warnings into errors. Implement much of the logic needed for C++0x deleted functions, which are effectively the same as "unavailable" functions (but always cause an error when referenced). However, we don't have the syntax to specify deleted functions yet :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64955 91177308-0d34-0410-b5e6-96231b3b80d8
