non-inline external definitions (and tentative definitions) that are
found at the top level. The corresponding declarations are stored in a
record in the PCH file, so that they can be provided to the
ASTConsumer (via HandleTopLevelDecl) when the PCH file is read.

Since ObjC 2.0 class "extensions" have a null name, the diagnostic above is actually "correct". Nevertheless, it is confusing. Decided to remove the name entirely (from my perspective, it didn't add any value). Also simplified the text of the diagnostic a bit.
llvm-svn: 68967
struct xyz { int y; };
enum abc { ZZZ };
static xyz b;
abc c;
we used to produce:
t2.c:4:8: error: unknown type name 'xyz'
static xyz b;
^
t2.c:5:1: error: unknown type name 'abc'
abc c;
^
we now produce:
t2.c:4:8: error: use of tagged type 'xyz' without 'struct' tag
static xyz b;
^
struct
t2.c:5:1: error: use of tagged type 'abc' without 'enum' tag
abc c;
^
enum
GCC produces the normal:
t2.c:4: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘b’
t2.c:5: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘c’

Implement the rvalue reference overload dance for returning local objects. Returning a local object first tries to find a move constructor now.
The error message when no move constructor is defined (or is not applicable) and the copy constructor is deleted is quite ugly, though.

@property int x;
associate the location of X with the property decl, not the location
of the @. Also, pass this info along to the synthesized ParmVarDecls
so that redefinition and other diagnostics can use it. This eliminates
a fixme.

that it is plumbed through Sema. On a file from growl, we used to emit:
t.mi:107059:1: warning: conflicting types for 'removePluginHandler:forPluginTypes:'
- (void) removePluginHandler:(id <GrowlPluginHandler>)handler forPluginTypes:(NSSet *)extensions {
^
t.mi:105280:1: note: previous definition is here
- (void) removePluginHandler:(id <NSObject>)handler forPluginTypes:(NSSet *)types;
^
now we produce:
t.mi:107059:55: warning: conflicting parameter types in implementation of 'removePluginHandler:forPluginTypes:': 'id<NSObject>' vs 'id<GrowlPluginHandler>'
- (void) removePluginHandler:(id <GrowlPluginHandler>)handler forPluginTypes:(NSSet *)extensions {
^
t.mi:105280:45: note: previous definition is here
- (void) removePluginHandler:(id <NSObject>)handler forPluginTypes:(NSSet *)types;
^
We still don't have proper loc info for properties, hence the FIXME.

1) improve localizability by not passing english strings in.
2) improve location for arguments.
3) print the objc type being passed.

after:

buffer generated for the current translation unit. If they are
different, complain and then ignore the PCH file. This effectively
checks for all compilation options that somehow would affect
preprocessor state (-D, -U, -include, the dreaded -imacros, etc.).
When we do accept the PCH file, throw away the contents of the
predefines buffer rather than parsing them, since all of the results
of that parsing are already stored in the PCH file. This eliminates
the ugliness with the redefinition of __builtin_va_list, among other
things.

clients of the analyzer to designate custom assertion routines as "noreturn"
functions from the analyzer's perspective but not the compiler's.

de-serialization of abstract syntax trees.
PCH support serializes the contents of the abstract syntax tree (AST)
to a bitstream. When the PCH file is read, declarations are serialized
as-needed. For example, a declaration of a variable "x" will be
deserialized only when its VarDecl can be found by a client, e.g.,
based on name lookup for "x" or traversing the entire contents of the
owner of "x".
This commit provides the framework for serialization and (lazy)
deserialization, along with support for variable and typedef
declarations (along with several kinds of types). More
declarations/types, along with important auxiliary structures (source
manager, preprocessor, etc.), will follow.

This allow us to document a simple migration path...change "Class <foo>" to "id <foo>".
This effects:

- <rdar://problem/6761864> Protocol qualified Class is unsupported

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.
