- Changed method names to match gcc (categories names still aren't
mangled in).
- Expose correct name for class and metadata symbols (although
-fvisibility=hidden isn't yet correct).
- Remove several things from llvm.used that didn't need to be there
(I suspect this can still be trimmed).
- Don't use asm-prefix extension for _objc_empty_{cache,vtable} (not
needed).
- Hide EH type class info with -fvisibility=hidden
- Change setGlobal[Option]Visibility to not change the visibility of
functions with internal linkage.

This will simplify clang adoption, and is probably better "etiquette" (since gcc has always accepted this idiom without warning). Once we are over the adoption hurdle, we can turn this into an error.

- <rdar://problem/6757236> clang should make a dSYM when going
straight from source to binary
- This still matches gcc, but the right way to solve this would be to
detect the situation we care about (we are compiling from source
and linking in one step), instead of looking at the suffix of the
input file. The Tool doesn't quite have enough information to do
this yet, however.
- Also, find the suffix correctly.

Eventually, would be nice to be able to run these modifications even
when we don't want the warning or errors for the actual diagnostic.

failures that involve malformed types, e.g., "typename X::foo" where
"foo" isn't a type, or "std::vector<void>" that doens't instantiate
properly.
Similarly, be a bit smarter in our handling of ambiguities that occur
in Sema::getTypeName, to eliminate duplicate error messages about
ambiguous name lookup.
This eliminates two XFAILs in test/SemaCXX, one of which was crying
out to us, trying to tell us that we were producing repeated error
messages.

- Finish up support for converting UTF8->UTF16 to support ObjC @"string" constants.
Remove warning from CheckObjCString.
As the FIXME in the test case indicates, I still have a bug to work out (apparently with \u handling).

heuristics to determine when it's useful to desugar a type for display
to the user. Introduce two C++-specific heuristics:
- For a qualified type (like "foo::bar"), only produce a new
desugred type if desugaring the qualified type ("bar", in this
case) produces something interesting. For example, if "foo::bar"
refers to a class named "bar", don't desugar. However, if
"foo::bar" refers to a typedef of something else, desugar to that
something else. This gives some useful desugaring such as
"foo::bar (aka 'int')".
- Don't desugar class template specialization types like
"basic_string<char>" down to their underlying "class
basic_string<char, char_traits<char>, allocator<char>>, etc.";
it's better just to leave such types alone.
Update diagnostics.html with some discussion and examples of type
preservation in C++, showing qualified names and class template
specialization types.

- <rdar://problem/6741594> [pth] don't abuse -x to drive pth
generation
- Simpler, and fixes PR3915.
Cleanup test cases for PTH:
- Update to use -emit-pth
- Removed PTH test of carbon.c and cocoa.mm; these didn't actually
verify anything, and since PTH is token based the extra coverage
(over cocoa.m) isn't particularly helpful.
- Split PTH tests in cocoa.m to cocoa-pth.m, solely to increase
available parallelism when running tests.
Ted, could you update the PTH test cases (include-pth.c and
cocoa-pth.m) to have some sort of positive check that the PTH is
getting used? "# of PTH cache hits" or "tokens read from PTH cache"
statistics would work great. :)

In a case like:
@class foo;
foo *P;
addRecordToClass was making an empty shadow struct for the foo interface and
completing it. Later when an:
@interface foo
...
@endif
foo *Q;
was seen, ASTContext::addRecordToClass would think that foo was already laid
out and not lay out the definition. This fixes it to create a forward declared
struct the first time around, then complete it when the definition is seen.
Note that this causes two tests to regress, because something is trying to get
the size of the forward declared structs returned by this. Previously, this
would end up getting a size of zero but now it properly dies. I'm not sure
what the right solution is for this, so I xfailed the tests.
Fariborz, please take a look at this. The testcase in rdar://6676794 now gets
farther, but dies later because the objc ivar is not assigned a field number.
As an aside, I really don't like the fact that the objc front-end is creating
shadow C structs for ObjC types. This seems like an implementation detail of
the code generator that could be fixed by better factoring of the extant code.
