Duncan Sands 0b875a0c29 When folding a load from a global constant, if the load started in the middle
of an array element (rather than at the beginning of the element) and extended
into the next element, then the load from the second element was being handled
wrong due to incorrect updating of the notion of which byte to load next.  This
fixes PR13442.  Thanks to Chris Smowton for reporting the problem, analyzing it
and providing a fix.

Richard Smith 2589b9808e PR12057: Allow variadic template pack expansions to cross lambda boundaries.
Rather than adding a ContainsUnexpandedParameterPack bit to essentially every
AST node, we tunnel the bit directly up to the surrounding lambda expression
when we reach a context where an unexpanded pack can not normally appear.
Thus any statement or declaration within a lambda can now potentially contain
an unexpanded parameter pack.

Akira Hatanaka 5a69c235ae Eliminate the stack slot used to save the global base register.
The long branch pass (fixed in r160601) no longer uses the global base register
to compute addresses of branch destinations, so it is not necessary to reserve
a slot on the stack.

Jordan Rose 68449acea4 Add __has_feature(attribute_availability_with_message).
This tests for the ability to include a "message" field in availability
attributes, like so:

  extern void ATSFontGetName(const char *oName)
    __attribute__((availability(macosx,introduced=8.0,deprecated=9.0,
                                message="use CTFontCopyFullName")));

This was actually supported in Clang 3.1, but we got a request for a
__has_feature so that header files can use this more safely. It's
unfortunate that the 3.1 release doesn't include this, however.

Rafael Espindola a44e193a11 In order to correctly compile
struct s {
  double x1;
  float x2;
};
__attribute__((regparm(3))) struct s f(int a, int b, int c);
void g(void) {
  f(41, 42, 43);
}

We need to be able to represent passing the address of s to f (sret) in a
register (inreg). Turns out that all that is needed is to not mark them as
mutually incompatible.

Kevin Enderby 216ac31971 Fix a bug in the x86 disassembler's symbolic disassembly support for Jcc-Jump
if Condition Is Met instuctions that was not correctly determining the target
instruction.

So for a jne rel32 instruction:

% cat x.s
.byte 0x0f, 0x85, 0x09, 0x00, 0x00, 0x00
% as x.s

it was incorrectly deterining the target:

% otool -q -tv a.out 
a.out:
(__TEXT,__text) section
0000000000000000	jne	0xd

and with the fix it gets this correct as:

% otool -q -tv a.out
a.out:
(__TEXT,__text) section
0000000000000000	jne	0xf

David Chisnall 5b8c1680de ELF does not imply GNU/Linux. Do not assume GNU conventions just because we
are targeting an ELF platform.  Only fold gs-relative (and fs-relative) loads
if it is actually sensible to do so for the target platform.

Hans Wennborg 84ce606b91 Tweak warning text for returning incomplete type from extern "C" functions.
A warning was added in r150128 for returning non-C compatible

decidedly non-C compatible, but incomplete.

Manuel Klimek 86f8bbced4 Introduces a new concept for binding results to matchers
as per Chandler's request:
- introduces a new matcher base type BindableMatcher that
  provides the bind() call
- makes all dynamic-cast matcher creation functions return
  BindableMatchers; the special case about dynamic-cast
  matchers is that the node they match on and the node
  their child matchers match on are the same node, just
  casted to a different type; thus, there is no ambiguity
  on what bind() matches on; additionally, those are the
  matchers that we name with nouns in the matcher language,
  so it's easy for users to intuitively know which matchers
  are bindable

To make this change possible, we got rid of a non-orthogonal
implementation of thisPointerType, which had an implicit
dynamic-cast matcher from CallExpr to CXXMemberCallExpr; as
alternative, we now provide a memberCall dynamic-cast matcher
and thisPointerType is a predicate on CXXMemberCallExpr.

Last, the ArgumentAdaptingMatcher is actually not required
for the implementation of makeDynCastAllOfComposite - this
simplification makes it more obvious where the bind() call
can be used based on the matcher creation function types.
