a member named 'swap' and then expect unqualified lookup for the name 'swap' in
its exception specification to find anything else.
Without delay-parsed exception specifications, this was ill-formed (NDR) by
[basic.scope.class]p1, rule 2. With delay-parsed exception specifications, the
call to 'swap' unambiguously finds the function being declared, which then
fails because the arguments don't work for that function.

Wire it through everywhere we have support for fastcall, essentially.
This allows us to parse the MSVC "14" CTP headers, but we will
miscompile them because LLVM doesn't support __vectorcall yet.

Clang supports __restrict__ as a function qualifier, but
DeclaratorChunk::FunctionTypeInfo lacked a field to track the qualifier's
source location (as we do with volatile, etc.). This was the subject of a FIXME
in GetFullTypeForDeclarator (in SemaType.cpp). This should also prove useful as
we add more warnings regarding questionable uses of the restrict qualifier.
There is no significant functional change (except for an improved source range
associated with the err_invalid_qualified_function_type diagnostic fixit
generated by GetFullTypeForDeclarator).

__super appeared. Name lookup is performed in all base classes of the

obviously supposed to be a parameter pack. Otherwise, warn if it immediately

to write a parameter pack followed by a C-style varargs ellipsis.
This warning can be syntactically disabled by using ", ..." instead of "...".

Array declarators involving the static keyword take on two forms:
D[ static type-qualifier-listopt assignment-expression ]
D[ type-qualifier-list static assignment-expression ]
Raise a diagnostic if the assignment-expression is missing.

Parser::ParseDeclarationSpecifiers eagerly updates the source range of
the DeclSpec with the current token position. However, it might not
consume any more tokens.
Fix this by only setting the start of the range, not the end. This way
the SourceRange will be invalid if we don't consume any more tokens.
This fixes PR20413.

If function parameters have default values, and that of the second
parameter is parsed with errors, function declaration would have
a parameter without default value that follows a parameter with
that. Such declaration breaks logic of selecting overloaded
function. As a solution, put opaque object as default value in such case.
This patch fixes PR20055.

Recognize additional cases, when '::' is mistyped as ':'.

Review is tracked by http://reviews.llvm.org/D3653.
This is an attempt to recommit the fix, initially committed as r212957 but then
reverted in r212965 as it broke self-build. In the updated patch ParseDirectDeclarator

When a user types:
int [4] foo;
assume that the user means:
int foo[4];
Update the information for 'foo' to prevent additional errors, and provide
a fix-it hint to move the brackets to the correct location.
Additionally, suggest parens for types that require it, such as:
int [4] *foo;
to:
int (*foo)[4];

MSVC delays parsing of default arguments until instantiation. If the
default argument is never used, it is never parsed. We don't model
this.
Instead, if lookup of a type name fails in a template argument context,
we form a DependentNameType, which will be looked up at instantiation
time.
This fixes errors about 'CControlWinTraits' in atlwin.h.

This removes a diagnostic that is no longer required (the semantic engine now properly handles attribute syntax so __declspec and __attribute__ spellings no longer get mismatched). This caused several testcases to need updating for a slightly different wording.

a missing include from CLog.h.
CLog.h referenced most of the core libclang types but never directly
included Index.h that provides them. Previously it got lucky and other
headers were always included first but with the sorting it ended up
first in one case and stopped compiling. Adding the Index.h include
fixes it right up.
