Dale Johannesen d2d4f6cad4 Use llvmgxx for C++ test.

Dan Gohman 03a7667349 Fix this test to account for a movl $0 being emitted as an xor now, 
and convert it to FileCheck.

Ted Kremenek b4ec3fc42d retain/release checker: Recognize that calls to 
'CVPixelBufferCreateWithPlanarBytes()' and
'CVPixelBufferCreateWithBytes' (Core Video API) can indirectly release
a pixel buffer object via a callback.

This fixes <rdar://problem/7283567>.

Dan Gohman 0be8c2b0e3 Make isSafeToClobberEFLAGS more aggressive. Teach it to scan backwards 
(for uses marked kill and defs marked dead) a few instructions in
addition to forwards. Also, increase the maximum number of instructions
to scan, as it appears to help in a fair number of cases.

Dan Gohman df777edea9 This remat entry is basically done. There are hooks to allow targets 
to remat non-load instructions as loads, and the remat code now uses
the UnmodeledSideEffects flags, MachineMemOperands, and similar things
to decide which instructions are valid for rematerialization.

Douglas Gregor 15e5602e59 Improve diagnostics when the parser encounters a declarator with an 
unknown type name, e.g.,

  foo::bar x;

when "bar" does not refer to a type in "foo". 

With this change, the parser now calls into the action to perform
diagnostics and can try to recover by substituting in an appropriate
type. For example, this allows us to easily diagnose some missing
"typename" specifiers, which we now do:

  test/SemaCXX/unknown-type-name.cpp:29:1: error: missing 'typename'
        prior to dependent type name 'A<T>::type'
  A<T>::type A<T>::f() { return type(); }
  ^~~~~~~~~~
  typename 

Fixes PR3990.

Ted Kremenek 80816acf9b retain/release checker: retained objects passed to pthread_create (as

Bob Wilson b62d160b3c More Neon clean-up: avoid the need for custom-lowering vld/st-lane intrinsics 
by creating TargetConstants during instruction selection instead of during
legalization.

Kevin Enderby f50799412c More bits of the ARM target assembler for llvm-mc to parse immediates. 
Also fixed a couple of coding style things that crept in.  And added more
to the temporary hacked up ARMAsmParser::MatchInstruction() method for testing.

Bob Wilson 1fdbe1152d NEON VLD/VST are now fully implemented. For operations that expand to 
multiple instructions, the expansion is done during selection so there is
no need to do anything special during legalization.

Douglas Gregor e40876a50c Unify our diagnostic printing for errors of the form, "we didn't like 
what we found when we looked into <blah>", where <blah> is a
DeclContext*. We can now format DeclContext*'s in nice ways, e.g.,
"namespace N", "the global namespace", "'class Foo'".

This is part of PR3990, but we're not quite there yet.

Duncan Sands 18a956cb4a Introduce new convenience methods for sign extending or 
truncating an SDValue (depending on whether the target
type is bigger or smaller than the value's type); or zero
extending or truncating it.  Use it in a few places (this
seems to be a popular operation, but I only modified cases
of it in SelectionDAGBuild).  In particular, the eh_selector
lowering was doing this wrong due to a repeated rather than
inverted test, fixed with this change.

Bob Wilson 3b51560ae4 Revise ARM inline assembly memory operands to require the memory address to 
be in a register.  The previous use of ARM address mode 2 was completely
arbitrary and inappropriate for Thumb.  Radar 7137468.
