and DefaultFunctionArrayLvalueConversion. To prevent
significant regression for should-this-be-a-call fixits,
and to repair some such regression from the introduction of
bound member placeholders, make those placeholder checks
try to build calls appropriately. Harden the build-a-call
logic while we're at it.

conversion function whose result type is an lvalue reference. The
initialization code already handled this properly, but overload
resolution was allowing the binding. Fixes PR11003 /

some arguments types are ns_consumed and some otherwise
matching types are not. This fixes the objc++ side only *auch*.

cannot be converted.
This is in preparation for overload resolution of initializer lists.
Currently, you will always get this message when you try to pass an init
list to an overloaded function.
llvm-svn: 140461
builds a semantic (structured) initializer list, just reports on whether it can match
the given list to the target type.
Use this mode for doing init list checking in the initial step of initialization, which
will eventually allow us to do overload resolution based on the outcome.

For example:
void f(float);
void f(int);
int main {
long a;
f(a);
}
Here, MSVC will call f(int) instead of generating a compile error as clang will do in standard mode.
This fixes a few errors when parsing MFC code with clang.

converting to an arbitrary Objective-C pointer type is. Without
significantly re-implementing anything, change the API to reflect this,
and as a minor optimization, strip the pointer conversion off before
potentially building it.
Mostly, this removes a really bizarre-looking bit of code from
BuildInstanceMessage.

than conversions of C pointers to ObjC pointers. In order to ensure that
we've caught every case, add asserts to CastExpr that strictly determine
which cast kind is used for which kind of bit cast.

Change TypoCorrection to store a set of NamedDecls instead of a single
NamedDecl. Also add initial support for performing function overload
resolution to Sema::DiagnoseEmptyLookup.

considering explicit conversion operators when determining surrogate
functions. Fixes PR10453. Note that there are a few test cases where
Clang is still wrong because it does not implement DR899; see PR10456.

IsIntegralPromotion should consider the signedness of FromType when
calculating promotions. This, as of now, cannot be exercised on any
platform so there is no corresponding test.

of a single if block. This is really annoying to track down and test.
Silly changes to the test case caused it to stop showing up. I wish
there were a more concrete way of asserting that a note attaches to the
intended diagnostic.
This fixes PR10195.

deducing template parameter types. Recently Clang began enforcing the
more strict checking that the argument type and the deduced function
parameter type (after substitution) match, but that only consideres
qualification conversions.
One problem with this patch is that we check noreturn conversions and
qualification conversions independently. If a valid conversion would
require *both*, perhaps interleaved with each other, it will be
rejected. If this actually occurs (I'm not yet sure it does) and is in
fact a problem (I'm not yet sure it is), there is a FIXME to implement
more intelligent conversion checking.
However, this step at least allows Clang to resume accepting valid code
we're seeing in the wild.

Language-design credit goes to a lot of people, but I particularly want
to single out Blaine Garst and Patrick Beard for their contributions.
Compiler implementation credit goes to Argyrios, Doug, Fariborz, and myself,
in no particular order.
