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.

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.

information in any of the resulting TypeLocs (yet), so it doesn't
matter.

* 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.

making them be template instantiated in a more normal way and
make them handle attributes like other decls.
This fixes the used/unused label handling stuff, making it use
the same infrastructure as other decls.

LabelDecl and LabelStmt. There is a 1-1 correspondence between the
two, but this simplifies a bunch of code by itself. This is because
labels are the only place where we previously had references to random
other statements, causing grief for AST serialization and other stuff.
This does cause one regression (attr(unused) doesn't silence unused
label warnings) which I'll address next.
This does fix some minor bugs:
1. "The only valid attribute " diagnostic was capitalized.
2. Various diagnostics printed as ''labelname'' instead of 'labelname'
3. This reduces duplication of label checking between functions and blocks.
Review appreciated, particularly for the cindex and template bits.

instead from the Scope; Inner scopes in bodies don't have DeclContexts associated with them.
Fixes http://llvm.org/PR9160 & rdar://problem/8966163.

say "out-of-line definition differ from the declaration in the return type" instead of
the silly "functions that differ only in their return type cannot be overloaded".
Addresses rdar://7980179.

The difference with gcc is that it warns if you overload virtual methods only if
the method doesn't also override any method. This is to cut down on the number of warnings
and make it more useful like reported here: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20423.
If we want to warn that not all overloads are overriden we can have an additional
warning like -Wpartial-override.
-Woverloaded-virtual, unlike gcc, is added to -Wmost. Addresses rdar://8757630.

extremely rambunctious, both on parsing and on template instantiation.
Calm it down, fixing an internal consistency assert on anonymous enum
instantiation manglings.

clang's -Wuninitialized-experimental warning.
While these don't look like real bugs, clang's
-Wuninitialized-experimental analysis is stricter
than GCC's, and these fixes have the benefit
of being general nice cleanups.

Inheritable attributes on declarations may be inherited by any later
redeclaration at merge time. By contrast, a non-inheritable attribute
will not be inherited by later redeclarations. Non-inheritable
attributes may be semantically analysed early, allowing them to
influence the redeclaration/overloading process.
Before this change, the "overloadable" attribute received special
handling to be treated as non-inheritable, while all other attributes
were treated as inheritable. This patch generalises the concept,
while removing a FIXME. Some CUDA location attributes are also marked
as non-inheritable in order to support special overloading semantics
(to be introduced in a later patch).
The patch introduces a new Attr subclass, InheritableAttr, from
which all inheritable attributes derive. Non-inheritable attributes
simply derive from Attr.
N.B. I did not review every attribute to determine whether it should
be marked non-inheritable. This can be done later on an incremental
basis, as this change does not affect default functionality.

there's a respectable point of instantiation. Also, make sure we do
this operation even when instantiating a dependently-typed variable.
