attribute as part of the calculation. Sema::MarkDeclReferenced(), and
a few other places, want only to consider the "used" bit to determine,
e.g, whether to perform template instantiation. Fixes a linkage issue
with Boost.Serialization.

The macros required for DeclNodes use have changed to match the use of
StmtNodes. The FooFirst enumerator constants have been named firstFoo
to match usage elsewhere.

the x86-64 __va_list_tag with this attribute. The attribute causes the
affected type to behave like a fundamental type when considered by ADL.
(x86-64 is the only target we currently provide with a struct-based
__builtin_va_list)
Fixes PR6762.

return value optimization. Sema marks return statements with their
NRVO candidates (which may or may not end up using the NRVO), then, at
the end of a function body, computes and marks those variables that
can be allocated into the return slot.
I've checked this locally with some debugging statements (not
committed), but there won't be any tests until CodeGen comes along.

common to name and then ignore an exception parameter. This warning is
neither enabled by default nor by -Wall. Fixes <rdar://problem/7931045>.

"extern" can become "static" if a prior declaration was static). Patch

Patch by Enea Zaffanella! Minimal adjustments: allocate the ExtInfo nodes
with the ASTContext and delete them during Destroy(). I audited a bunch of
Destroy methods at the same time, to ensure that the correct teardown was
being done.

previously only had a single location (the @ in @interface); now we
know where the @ is (for the start of the declaration), where the
class name is (that's the normal "location" now for diagnostics), and
where the category name is. Also, eliminated the redundant "end"
location, since ObjCContainerDecl already has better @end information.
The only XFAIL'd test is temporary; will un-XFAIL-it once I've taught
CIndex how to use the new locations.

piece of the declaration. The '@' and the 'end' are separate tokens,
and require two SourceLocations to accurately track.
This change was motivated because ObjCContainerDecl::getSourceRange()
would previously not return the entire range of the declaration (the
'end' would be left off).

"integer promotion" type associated with an enum decl, and use this type to
determine which type to promote to. This type obeys C++ [conv.prom]p2 and
is therefore generally signed unless the range of the enumerators forces
it to be unsigned.

I'm healthily ignoring the vector type cases because we don't have a sensible
TypeLoc implementation for them anyway.

in the DeclaratorInfo, if one is present.
Preserve source information through template instantiation. This is made
more complicated by the possibility that ParmVarDecls don't have DIs, which
is possibly worth fixing in the future.
Also preserve source information for function parameters in ObjC method
declarations.

format, so that we don't end up with multiple declaration and types
blocks. Also, fix a few obscure bugs with PCH loading and generation:
- If the DeclIDs DenseMap reallocates while we are writing a
declaration (due to recursively writing other declarations), we
could end up writing a bad ID to ExternalDefinitions.
- When loading an ArrayLoc (part of DeclaratorInfo), we need to set
the size expression to NULL if no size expression was provided.
PCH -> AST rewriting is still partly broken, unfortunately.

header or not via a new "PCHLevel" field in Decl. We currently use
this information to help CIndex filter out declarations that came from
a precompiled header (rather than from an AST file). Further down the
road, it can be used to help implement multi-level precompiled
headers.

most of the unsafe boilerplate out of TypeLoc. Create a QualifiedLoc class
to represent the idea that we *might* start representing source locations
of qualifiers. Dealing with qualifiers explicitly like this also lets us
efficiently ignore them in all the concrete cases.
This should make it obvious and easy to add new TypeLoc subclasses.

This still isn't perfect, but I believe it is conservatively accurate at marking decls which IRgen needs to see, while still keeping the "deserialization footprint" on Cocoa.h.

cleaner, and fixes PR4536.
