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.

A recent regression caused by http://llvm.org/viewvc/llvm-project?rev=65912&view=rev.
This commit isn't fully baked. Nevertheless, it should cause Xcode to compile again. Will speak with Fariborz offline.

- Disallow casting 'super'. GCC allows this, however it doesn't make sense (super isn't an expression and the cast won't alter lookup/dispatch).
- Tighten up lookup when messaging 'self'.

And now, when clang check a class implementation to find unimplemented methods, it also checks all methods from the class extensions (unnamed categories).
There is also a test case to check this warning.
This patch contains also a minor update for ObjCImplDecl . getNameAsCString and getNameAsString now returns an empty string instead of crashing for unnamed categories."

Needed to make isPropertyReadonly() non-const (for this fix to compile). I imagine there's a way to retain the const-ness, however I have more important fish to fry.

The code for looking up local/private method in Sema::ActOnInstanceMessage() was not handling categories properly. Sema::ActOnClassMessage() didn't have this bug.
Created a helper with the correct logic and changed both methods to use it.
llvm-svn: 65532
Also changed ObjCInterfaceDecl::lookupClassMethod() to look through a categories protocols.
Test/patch submitted by Jean-Daniel Dupas (thanks!).

assertion when the ivars and method list was reset into the existing
interface. To fix this, mark decls as invalid when they are redefined,
and don't insert ivars/methods into invalid decls.

- 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.

Found while researching <rdar://problem/6497631> Message lookup is sometimes different than gcc's.
Will never be seen in user code. Needed to pass dejagnu testsuite.

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.

(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 :)

First step, handle diagnostics in StringLiteral's that are due to token pasting.
For example, we now handle:
id str2 = @"foo"
"bar"
@"baz"
" b\0larg"; // expected-warning {{literal contains NUL character}}
Correctly:
test/SemaObjC/exprs.m:17:15: warning: CFString literal contains NUL character
" b\0larg"; // expected-warning {{literal contains NUL character}}
~~~^~~~~~~
There are several other related issues still to be done.
