E.g. the codegen result is 
     fmls v1.2s, v0.2s, v2.s[3]
which is expected to be
     fmls v0.2s, v1.2s, v2.s[3]

[Sanitizer] Replace Symbolizer::IsAvailable and Symbolizer::IsExternalAvailable with Symbolizer::CanReturnFileLineInfo.
Remove now redundant checks in symbolizer initialization in TSan and MSan.

LOAD AND ADD LOGICAL isn't really separately useful for LLVM.

Before:
  Constructor() : a(a) {}

After:
  Constructor()

This style guide is pretty precise about this.

This is intended to address the following problem.
Episodically we see CHECK-failures when recursive interceptors call back into user code. Effectively we are not "in_rtl" at this point, but it's very complicated and fragile to properly maintain in_rtl property. Instead get rid of it. It was used mostly for sanity CHECKs, which basically never uncover real problems.
Instead introduce ignore_interceptors flag, which is used in very few narrow places to disable recursive interceptors (e.g. during runtime initialization).

llvm-svn: 197979

Those methods were too damn bloated.

Print the list of leaked objects after each leak report. Previously we
printed only a joint list of all leaked objects. As a bonus, suppressed objects
are no longer reported.

Introduce proper facilities to render token spellings using the diagnostic
formatter.

Replaces most of the hard-coded diagnostic messages related to expected tokens,
which all shared the same semantics but had to be multiply defined due to
variations in token order or quote marks.

The associated parser changes are largely mechanical but they expose
commonality in whole chunks of the parser that can now be factored away.

This commit uses C++11 typed enums along with a speculative legacy fallback
until the transition is complete.

Requires corresponding changes in LLVM r197895.

DAG.getVectorShuffle() doesn't always return a vector_shuffle node.
If mask is the exact sequence of it's operand(For example, operand_0
is v8i8, and  the mask is 0, 1, 2, 3, 4, 5, 6, 7), it will directly
return that operand. So a check is added here.

This failure caused by improper condition when lowering shuffle_vector
to scalar_to_vector. After this patch NEON_VDUP with v1i64 will not

These still have "experimental" status, meaning we don't guarantee
backward compatibility. However, they are already actively used by the
open source WebKit project, and have started to be adopted by other
projects.

Check for single use of fmul node in fused multiply patterns
to allow generation of fused multiply add/sub instructions.
Otherwise fmul operation ends up being repeated more than
once which does not help peformance on targets with
only one MAC unit, as for example cortex-a53.

The correct pattern matching should be:

- fnmadd is (-Ra) + (-Rn)*Rm  which should be matched as:

  fma (fneg node:$Rn),  node:$Rm, (fneg node:$Ra) and as

  (f32 (fsub (f32 (fneg FPR32:$Ra)), (f32 (fmul FPR32:$Rn, FPR32:$Rm))))

- fnmsub is (-Ra) + Rn*Rm which should be matched as

  fma node:$Rn,  node:$Rm, (fneg node:$Ra) and as

  (f32 (fsub (f32 (fmul FPR32:$Rn, FPR32:$Rm)), FPR32:$Ra))))

Split sadd.with.overflow into add + sadd.with.overflow to allow
analysis and optimization. This should ideally be done after
InstCombine, which can perform code motion (eventually indvars should
run after all canonical instcombines). We want ISEL to recombine the
add and the check, at least on x86.

This is currently under an option for reducing live induction
variables: -liv-reduce. The next step is reducing liveness of IVs that
are live out of the overflow check paths. Once the related
optimizations are fully developed, reviewed and tested, I do expect
this to become default.

Remove wait_for_launch parameter from DoAttachToProcessWithName(). This parameter is redundant as this information is already provided by the ProcessAttachInfo parameter.
