Francois Pichet 1c229c0472 Add -fdelayed-template-parsing option. Using this option all templated function definitions are parsed at the end of the translation unit only if it is required by an actual instantiation. As such all the symbols of the TU are available during name lookup.
Using this flag is necessary for compatibility with Microsoft template code.
This also provides some parsing speed improvement.

Fariborz Jahanian c057794adb Fixes an instance method meta-data generation bug in
ObjC NeXt runtime where method pointer registered in

I turned at @end missing warning (for class
implementations) into an error as we can never
be sure that meta-data being generated is correct.

Douglas Gregor 20b2ebd785 Implement a new 'availability' attribute, that allows one to specify
which versions of an OS provide a certain facility. For example,

  void foo()
  __attribute__((availability(macosx,introduced=10.2,deprecated=10.4,obsoleted=10.6)));

says that the function "foo" was introduced in 10.2, deprecated in
10.4, and completely obsoleted in 10.6. This attribute ties in with
the deployment targets (e.g., -mmacosx-version-min=10.1 specifies that
we want to deploy back to Mac OS X 10.1). There are several concrete
behaviors that this attribute enables, as illustrated with the
function foo() above:

  - If we choose a deployment target >= Mac OS X 10.4, uses of "foo"
    will result in a deprecation warning, as if we had placed
    attribute((deprecated)) on it (but with a better diagnostic)
  - If we choose a deployment target >= Mac OS X 10.6, uses of "foo"
    will result in an "unavailable" warning (in C)/error (in C++), as
    if we had placed attribute((unavailable)) on it
  - If we choose a deployment target prior to 10.2, foo() is
    weak-imported (if it is a kind of entity that can be weak
    imported), as if we had placed the weak_import attribute on it.

Naturally, there can be multiple availability attributes on a
declaration, for different platforms; only the current platform
matters when checking availability attributes.

The only platforms this attribute currently works for are "ios" and
"macosx", since we already have -mxxxx-version-min flags for them and we
have experience there with macro tricks translating down to the
deprecated/unavailable/weak_import attributes. The end goal is to open
this up to other platforms, and even extension to other "platforms"
that are really libraries (say, through a #pragma clang
define_system), but that hasn't yet been designed and we may want to
shake out more issues with this narrower problem first.

Addresses <rdar://problem/6690412>.

As a drive-by bug-fix, if an entity is both deprecated and
unavailable, we only emit the "unavailable" diagnostic.

headers, which use C++0x generalized initializer lists. Per PR7069, it
appears that the only use is as the return type of a function, so this
commit enables this extension just in that narrow case. If it's enough
for libstdc++ 4.5, or if it can be trivially extended to work with
libstdc++ 4.5, we'll keep it. Otherwise, or if this breaks anything,
we'll revert and wait for the real feature.

Douglas Gregor e7c2065379 Push nested-name-specifier source-location information into dependent
template specialization types. This also required some parser tweaks,
since we were losing track of the nested-name-specifier's source
location information in several places in the parser. Other notable
changes this required:

  - Sema::ActOnTagTemplateIdType now type-checks and forms the
    appropriate type nodes (+ source-location information) for an
    elaborated-type-specifier ending in a template-id. Previously, we
    used a combination of ActOnTemplateIdType and
    ActOnTagTemplateIdType that resulted in an ElaboratedType wrapped
    around a DependentTemplateSpecializationType, which duplicated the
    keyword ("class", "struct", etc.) and nested-name-specifier
    storage.

  - Sema::ActOnTemplateIdType now gets a nested-name-specifier, which
    it places into the returned type-source location information.

  - Sema::ActOnDependentTag now creates types with source-location
    information.

Douglas Gregor 844cb50266 Reinstate the introduction of source-location information for
nested-name-speciciers within elaborated type names, e.g.,
 
  enum clang::NestedNameSpecifier::SpecifierKind

Fixes in this iteration include:

  (1) Compute the type-source range properly for a dependent template
  specialization type that starts with "template template-id ::", as
  in a member access expression

    dep->template f<T>::f()

  This is a latent bug I triggered with this change (because now we're
  checking the computed source ranges for dependent template
  specialization types). But the real problem was...

  (2) Make sure to set the qualifier range on a dependent template
  specialization type appropriately. This will go away once we push
  nested-name-specifier locations into dependent template
  specialization types, but it was the source of the
  valgrind errors on the buildbots.

Douglas Gregor bf5fe47b12 Reinstate r126737, extending the generation of type-source location
information for qualifier type names throughout the parser to address
several problems.

The commit message from r126737:

Push nested-name-specifier source location information into elaborated
name types, e.g., "enum clang::NestedNameSpecifier::SpecifierKind".

Aside from the normal changes, this also required some tweaks to the
parser. Essentially, when we're looking at a type name (via
getTypeName()) specifically for the purpose of creating an annotation
token, we pass down the flag that asks for full type-source location
information to be stored within the returned type. That way, we retain
source-location information involving nested-name-specifiers rather
than trying to reconstruct that information later, long after it's
been lost in the parser.

With this change, test/Index/recursive-cxx-member-calls.cpp is showing
much improved results again, since that code has lots of
nested-name-specifiers.

Douglas Gregor b09518c551 Eliminate a silly little Parse/Sema dance when parsing typename
specifiers such as

Previously, we would turn T::template apply<U> into a
TemplateSpecializationType. Then, we'd reprocess that
TemplateSpecializationType and turn it into either a
TemplateSpecializationType wrapped in an ElaboratedType (when we could
resolve "apply" to a template declaration) or a
DependentTemplateSpecializationType. We now produce the same ASTs but
without generating the intermediate TemplateSpecializationType.

The end goal here is to avoid generating TemplateSpecializationTypes
with dependent template-names, ever. We're not there yet.

Richard Smith b2bc2e6752 Tweaks to C++0x deduced auto type support:
* Flag indicating 'we're parsing this auto typed variable's initializer' moved from VarDecl to Sema
 * Temporary template parameter list for auto deduction is now allocated on the stack.
 * Deduced 'auto' types are now uniqued.

John McCall c146582e60 When parsing an out-of-line member function declaration, we must delay
access-control diagnostics which arise from the portion of the declarator
following the scope specifier, just in case access is granted by
friending the individual method.  This can also happen with in-line
member function declarations of class templates due to templated-scope
friend declarations.

We were really playing fast-and-loose before with this sort of thing,
and it turned out to work because *most* friend functions are in file
scope.  Making us delay regardless of context exposed several bugs with
how we were manipulating delay.  I ended up needing a concept of a
context that's independent of the declarations in which it appears,
and then I actually had to make some things save contexts correctly,
but delay should be much cleaner now.

I also encapsulated all the delayed-diagnostics machinery in a single
subobject of Sema;  this is a pattern we might want to consider rolling
out to other components of Sema.

extension.
