62f973306c [ARM] Reject invalid -march values
Restructure Triple::getARMCPUForArch so that invalid values will
return nullptr, while retaining the behaviour that an argument
specifying no particular architecture version will give a default
CPU. This will be used by clang to give an error on invalid -march
values.

Also restructure the extraction of the architecture version from
the MArch string a little to hopefully make what it's doing clearer.

4462e6d1b0 This change is refactoring only. It moves basic block normalization for invokes to happen before replacement of a call with safepoint in "ReplaceWithStatepoint". Previously it was partly done before replacement of calls with safepoint and partly after call replacement but before RAUW's for gc_relocates, which was confusing.

ca33d72658 [mips] Emit the .insn directive for empty basic blocks.
Summary:
In microMIPS, labels need to know whether they are on code or data. This is
indicated with STO_MIPS_MICROMIPS and can be inferred by being followed
by instructions. For empty basic blocks, we can ensure this by emitting the
.insn directive after the label.

Also, this fixes some failures in our out-of-tree microMIPS buildbots, for the
exception handling regression tests under: SingleSource/Regression/C++/EH

So unexpected section type inside writeSectionContent method indicates

e4eff4b231 Clear kill flags in tail duplication.
If we duplicate an instruction then we must also clear kill flags on any uses we rewrite.
Otherwise we might be killing a register which was used in other BBs.

For example, here the entry BB ended up with these instructions, the ADD having been tail duplicated.

	%vreg24<def> = t2ADDri %vreg10<kill>, 1, pred:14, pred:%noreg, opt:%noreg; GPRnopc:%vreg24 rGPR:%vreg10
	%vreg22<def> = COPY %vreg10; GPR:%vreg22 rGPR:%vreg10

	The copy here is inserted after the add and so needs vreg10 to be live.

9e31c0cf91 YAML: Enable the YAMLParser tests.
This commit enables the tests located in test/YAMLParser directory.
Those tests were never actually enabled, as llvm-lit didn't pick up the
files with the 'data' extension. The commit renames those test files to files
with the 'test' extension so that llvm-lit would find them.

This commit also modifies yaml-bench so that it returns an error status
if an error occurred during parsing. It also adds the '-use-color'
command line option to yaml-bench (to make sure that file check matches
the error messages in the output stream).

This commit modifies some of the renamed tests so that they wouldn't
fail. It gets rid of XFAILs and uses the 'not' command instead for
some of the tests that have to fail during parsing. This commit
also adds some 'FIXME' comments to a couple of tests that are
supposed to fail but currently pass because of various bugs
in the implementation of the yaml parser.

aa46024ea3 Fix information loss in branch probability computation.
Summary:
This addresses PR 22718. When branch weights are too large, they were
being clamped to the range [1, MaxWeightForBB]. But this clamping is
only applied to edges that go outside the range, so it distorts the
relative branch probabilities.

This patch changes the weight calculation to scale every branch so the
relative probabilities are preserved. The scaling is done differently
now. First, all the branch weights are added up, and if the sum exceeds
32 bits, it computes an integer scale to bring all the weights within
the range.

The patch fixes an existing test that had slightly wrong branch
probabilities due to the previous clamping. It now gets branch weights
scaled accordingly.

This is a follow-on to r236740 where I took Andrea's advice

AFAICT, there is no change in the final code produced because

by the more complicated pattern.

39cf555429 [x86] eliminate unnecessary shuffling/moves with unary scalar math ops (PR21507)
Finish the job that was abandoned in D6958 following the refactoring in
http://reviews.llvm.org/rL230221:

1. Uncomment the intrinsic def for the AVX r_Int instruction.
2. Add missing r_Int entries to the load folding tables; there are already
   tests that check these in "test/Codegen/X86/fold-load-unops.ll", so I
   haven't added any more in this patch.
3. Add patterns to solve PR21507 ( https://llvm.org/bugs/show_bug.cgi?id=21507 ).

So instead of this:

  movaps	%xmm0, %xmm1
  rcpss	%xmm1, %xmm1
  movss	%xmm1, %xmm0

We should now get:

  rcpss	%xmm0, %xmm0

And instead of this:

  vsqrtss	%xmm0, %xmm0, %xmm1
  vblendps	$1, %xmm1, %xmm0, %xmm0 ## xmm0 = xmm1[0],xmm0[1,2,3]

We should now get:

  vsqrtss	%xmm0, %xmm0, %xmm0
