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.

instance variables:
- Use isRecordType() rather than isa<RecordType>(), so that we see
through typedefs in ivar types.
- Mark the destructor as referenced
- Perform C++ access control on the destructor

template names. We were completely missing naming classes for many unqualified
lookups, but this didn't trigger code paths that need it. This removes part of
an optimization that re-uses the template name lookup done by the parser to
determine if explicit template arguments actually form a template-id.
Unfortunately the technique for avoiding the duplicate lookup lost needed data
such as the class context in which the lookup succeeded.

non-function-local declarations with names similar to what the user
typed. For example, this allows us to correct 'supper' to 'super' in
an Objective-C message send, even though the C function 'isupper' has
the same edit distance.
llvm-svn: 104023
consider "super" as a candidate whenever we're parsing an expression
within an Objective-C method in an interface that has a superclass. At
some point, we'd like to give "super" a little edge over non-local
names; that will come later.

way that C does. Among other differences, elaborated type specifiers
are defined to skip "non-types", which, as you might imagine, does not
include typedefs. Rework our use of IDNS masks to capture the semantics
of different kinds of declarations better, and remove most current lookup
filters. Removing the last remaining filter is more complicated and will
happen in a separate patch.
Fixes PR 6885 as well some spectrum of unfiled bugs.

generally recover from typos in keywords (since we would effectively
have to mangle the token stream). However, there are still benefits to
typo-correcting with keywords:
- We don't make stupid suggestions when the user typed something
that is similar to a keyword.
- We can suggest the keyword in a diagnostic (did you mean
"static_cast"?), even if we can't recover and therefore don't have
a fix-it.

than just a bool indicating that correction occurred. No actual
functionality change (it's still always used like a bool), but this
refactoring will be used to support typo correction to keywords.

This introduces FunctionType::ExtInfo to hold the calling convention and the
noreturn attribute. The next patch will extend it to include the regparm
attribute and fix the bug.

access to the (elevated) access of the accessed declaration, if applicable,
rather than plunking that access onto the end after we've calculated the
inheritance access.
Also, being a friend of a derived class gives you public access to its
members (subject to later modification by further inheritance); it does
not simply ignore a single location of restricted inheritance.
Also, when computing the best unprivileged path to a subobject, preserve
the information that the worst path might be AS_none (forbidden) rather
than a minimum of AS_private.

parameter hides a namespace-scope declararion with the same name in an
out-of-line definition of a template. The lookup requires a strange
interleaving of lexical and semantic scopes (go C++), which I have not
yet handled in the typo correction/code completion path.

name lookup rules for ivars, which are of course completely different
from and incompatible with the Objective-C++ rules.
For the record, the Objective-C++ rules are the sane ones.

This is to address a serious performance problem observed when running
'clang -fsyntax-only' on really broken source files. In one case,
repeatedly calling CorrectTypo() caused one source file to be rejected
after 2 minutes instead of 1 second.
This patch causes typo correction to take neglible time on that file
while still providing correction results for the first 20 cases. I
felt this was a reasonable number for moderately broken source files.
I don't claim this is the best solution. Comments welcome. It is
necessary for us to address this issue because it is a serious
performance problem.

This solution relies on an O(n) scan of redeclarations, which means it might
scale poorly in crazy cases with tons of redeclarations brought in by a ton
of distinct associated namespaces. I believe that avoiding this
is not worth the common-case cost.
