Tim Northover 28fc0e1fcd ARMv7k: define __ARM_PCS_VFP since we're hard-float.
It's a little debateable because we're not truly AAPCS, so I'm
certainly not going to define __ARM_PCS, but __ARM_PCS_VFP seems to be
really an "hard-float" define, which is a useful thing to have.

Simon Pilgrim bd4a3be7d2 [InstCombine][SSE] Add MOVMSK support to SimplifyDemandedUseBits
The MOVMSK instructions copies a vector elements' sign bits to the low bits of a scalar register and zeros the high bits.

This patch adds MOVMSK support to SimplifyDemandedUseBits so that its aware that the upper bits are known to be zero. It also removes the call to MOVMSK if none of the lower bits are actually required and just returns zero.

Silviu Baranga 632fdc5919 PR27216: Only define __ARM_FEATURE_FMA when the target has VFPv4
Summary:
According to the ACLE spec, "__ARM_FEATURE_FMA is defined to 1 if
the hardware floating-point architecture supports fused floating-point
multiply-accumulate".

This changes clang's behaviour from emitting this macro for v7-A and v7-R
cores to only emitting it when the target has VFPv4 (and therefore support
for the floating point multiply-accumulate instruction).

Fixes PR27216

Denis Zobnin 2008dbb4ed [MS] Improved implementation of MS stack pragmas (vtordisp, *_seg)
Rework implementation of several MS pragmas that use internal stack:
vtordisp, {bss|code|const|data}_seg.
This patch:
  1. Makes #pragma vtordisp use PragmaStack class as *_seg pragmas do;
  2. Fixes "#pragma vtordisp()" behavior: it shouldn't affect stack;
  3. Saves/restores the stacks on enter/exit a C++ method body.

Kuba Brecka dc7b607b09 [tsan] Fix Darwin GCD support after separation of Processor and ThreadState
Recent TSan changes (r267678) which factor out parts of ThreadState into a Processor structure broke worker threads on OS X.  This fixes it by properly calling ProcCreate for GCD worker threads and by replacing some CHECKs with RAW_CHECK in early process initialization.  CHECK() in TSan calls the allocator, which requires a valid Processor.

Alexey Bataev 2b19a6fe53 [OPENMP 4.5] Codegen for 'grainsize/num_tasks' clauses of 'taskloop'
directive.

OpenMP 4.5 defines 'taskloop' directive and 2 additional clauses
'grainsize' and 'num_tasks' for this directive. Patch adds codegen for
these clauses.
These clauses are generated as arguments of the '__kmpc_taskloop'
libcall and are encoded the following way:

void __kmpc_taskloop(ident_t *loc, int gtid, kmp_task_t *task, int if_val, kmp_uint64 *lb, kmp_uint64 *ub, kmp_int64 st, int nogroup,  int sched, kmp_uint64 grainsize, void *task_dup);

If 'grainsize' is specified, 'sched' argument must be set to '1' and
'grainsize' argument must be set to the value of the 'grainsize' clause.
If 'num_tasks' is specified, 'sched' argument must be set to '2' and
'grainsize' argument must be set to the value of the 'num_tasks' clause.
It is possible because these 2 clauses are mutually exclusive and can't
be used at the same time on the same directive.
If none of these clauses is specified, 'sched' argument must be set to
'0'.

Matthias Braun fbe85ae12e CodeGen: Add DetectDeadLanes pass.
The DetectDeadLanes pass performs a dataflow analysis of used/defined
subregister lanes across COPY instructions and instructions that will
get lowered to copies. It detects dead definitions and uses reading
undefined values which are obscured by COPY and subregister usage.

These dead definitions cause trouble in the register coalescer which
cannot deal with definitions suddenly becoming dead after coalescing
COPY instructions.

For now the pass only adds dead and undef flags to machine operands. It
should be possible to extend it in the future to remove the dead
instructions and redo the analysis for the affected virtual
registers.

Matthias Braun ff04541f4a TableGen: Support lanemasks for classes without subregisters
Previously using lanemasks on registers without any subregisters was not

- Report a lanemask of 1 for regclasses without subregisters
- Do the right thing when mapping a 0/1 lanemask from a class without
  subregisters into a class with subregisters in
  TargetRegisterInfo::composeSubRegIndexLaneMasks().

This will be used in the upcoming "DetectDeadLanes" patch.

Jim Ingham deb384d103 Fix an inefficiency in the handling of $__lldb_local_vars in expressions.
The code in ClangExpressionDeclMap::FindExternalVisibleDecls figures out what the token 
means, and adds the namespace to the lookup context, but since it doesn't mark it as
special in the search context, we go on to pass the name $__lldb_local_vars to the ASTSource
for further lookup.  Unless we've done our job wrong, those lookups will always fail, but
the can be costly.

So I added a bit to m_found & use that to short-circuit the lookup.
