might be queried in places where we absolutely require a valid
location (e.g., for template instantiation). Fixes some major
brokenness in the use of __is_convertible_to.

access control errors into SFINAE errors, so that the trait provides
enough support to implement the C++0x std::is_convertible type trait.
To get there, the SFINAETrap now knows how to set up a SFINAE context
independent of any template instantiations or template argument
deduction steps, and (separately) can set a Sema flag to translate
access control errors into SFINAE errors. The latter can also be
useful if we decide that access control errors during template argument
deduction should cause substitution failure (rather than a hard error)
as has been proposed for C++0x.

semantics after the C++0x is_convertible type trait. This
implementation is not 100% complete, because it allows access errors
to be hard errors (rather than just evaluating false).
Original patch by Steven Watanabe!

deallocation function has a two-argument form. Store the result of this
check in new[] and delete[] nodes.
Fixes rdar://problem/8913519
llvm-svn: 124373
derived-to-base cast that also casts away constness (one of the cases
for static_cast followed by const_cast) would be treated as a bit-cast
rather than a derived-to-base class, causing miscompiles and
heartburn.
Fixes <rdar://problem/8913298>.

overload a function without a ref-qualifier (C++0x
[over.load]p2). This, apparently, completes the implementation of
rvalue references for *this.
llvm-svn: 124321
reference binding is for the implicit object parameter of a member
function with a ref-qualifier. My previous comment, that we didn't
need to track this explicitly, was wrong: we do in fact get
rvalue-references-prefer-rvalues overloading with ref-qualifiers.

using rules that I just made up this morning. This encoding has now
been proposed to the Itanium C++ ABI group for inclusion, but of
course it's still possible that the mangling will change.
llvm-svn: 124296
- Don't publicize a C++0x feature through __has_feature if we aren't
in C++0x mode (even if the feature is available only with a
warning).
- "auto" is not implemented well enough for its __has_feature to be
turned on.
- Fix the test of C++0x __has_feature to actually test what we're
trying to test. Searching for the substring "foo" when our options
are "foo" and "no_foo" doesn't work :)
llvm-svn: 124291
- Add ref-qualifiers to the type system; they are part of the
canonical type. Print & profile ref-qualifiers
- Translate the ref-qualifier from the Declarator chunk for
functions to the function type.
- Diagnose mis-uses of ref-qualifiers w.r.t. static member
functions, free functions, constructors, destructors, etc.
- Add serialization and deserialization of ref-qualifiers.
llvm-svn: 124281
for reference binding (C++ [over.rank.ics]p3b1sb4), so that we prefer
the binding of an lvalue reference to a function lvalue over the
binding of an rvalue reference. This change resolves the ambiguity
with std::forward and lvalue references to function types in a way
that seems consistent with the original rvalue references proposal.
My proposed wording for this change is shown in
isBetterReferenceBindingKind(); we'll try to get this change adopted
in the C++0x working paper as well.

authors to write
class __attribute__((forbid_temporaries)) Name { ... };
when they want to force users to name all variables of the type. This protects
people from doing things like creating a scoped_lock that only lives for a
single statement instead of an entire scope.
The warning produced by this attribute can be disabled by
-Wno-forbid-temporaries.

generate meaningful [*] template argument location information.
[*] Well, as meaningful as possible, given that this entire code path
is a hack for when we've lost type-source information.

and turn on __has_feature(cxx_rvalue_references). The core rvalue
references proposal seems to be fully implemented now, pending lots
more testing.
llvm-svn: 124169
We translate property accesses to obj-c messages by simulating "loads" or "stores" to properties
using a pseudo-location SVal kind (ObjCPropRef).
Checkers can now reason about obj-c messages for both explicit message expressions and implicit
messages due to property accesses.
llvm-svn: 124161
messages that are sent for handling properties in dot syntax.
Replace all direct uses of ObjCMessageExpr in the checkers and checker interface with ObjCMessage.
