I added a triple to the test that was failing so that it would have failed
on Linux.

fb4ffccacb If a conditional branch jumps to the same target, remove the condition
Given that large parts of inst combine is restricted to instructions which have one use, getting rid of a use on the condition can help the effectiveness of the optimizer. Also, it allows the condition to potentially be deleted by instcombine rather than waiting for another pass.

I noticed this completely by accident in another test case. It's not anything that actually came from a real workload.

p.s. We should probably do the same thing for switch instructions.

107918efa2 Emit correct linkage-name attribute based on DWARF version.
There are still 4 tests that check for DW_AT_MIPS_linkage_name,
because they specify DWARF 2 or 3 in the module metadata. So, I didn't
create an explicit version-based test for the attribute.

7c7b72a066 Infer known bits from dominating conditions
This patch adds limited support in ValueTracking for inferring known bits of a value from conditional expressions which must be true to reach the instruction we're trying to optimize. At this time, the feature is off by default. Once landed, I'm hoping for feedback from others on both profitability and compile time impact.

Forms of conditional value propagation have been tried in LLVM before and have failed due to compile time problems.  In an attempt to side step that, this patch only considers conditions where the edge leaving the branch dominates the context instruction. It does not attempt full dataflow.  Even with that restriction, it handles many interesting cases:
 * Early exits from functions
 * Early exits from loops (for context instructions in the loop and after the check)
 * Conditions which control entry into loops, including multi-version loops (such as those produced during vectorization, IRCE, loop unswitch, etc..)

Possible applications include optimizing using information provided by constructs such as: preconditions, assumptions, null checks, & range checks.

This patch implements two approaches to the problem that need further benchmarking.  Approach 1 is to directly walk the dominator tree looking for interesting conditions.  Approach 2 is to inspect other uses of the value being queried for interesting comparisons.  From initial benchmarking, it appears that Approach 2 is faster than Approach 1, but this needs to be further validated.

7775242da3 [CodeGenPrepare] Refine the cost model provided by the promotion helper.
- Use TargetLowering to check for the actual cost of each extension.
- Provide a factorized method to check for the cost of an extension:
  TargetLowering::isExtFree.
- Provide a virtual method TargetLowering::isExtFreeImpl for targets to be able
  to tune the cost of non-free extensions.

This refactoring offers a better granularity to model what really happens on
different targets.

No performance changes and very few code differences.

4a3cd42601 [AArch64] Avoid going through GPRs for across-vector instructions.
This adds new node types for each intrinsic.
For instance, for addv, we have AArch64ISD::UADDV, such that:
  (v4i32 (uaddv ...))
is the same as
  (v4i32 (scalar_to_vector (i32 (int_aarch64_neon_uaddv ...))))
that is,
  (v4i32 (INSERT_SUBREG (v4i32 (IMPLICIT_DEF)),
           (i32 (int_aarch64_neon_uaddv ...)), ssub)

In a combine, we transform all such across-vector-lanes intrinsics to:

  (i32 (extract_vector_elt (uaddv ...), 0))

This has one big advantage: by making the extract_element explicit, we
enable the existing patterns for lane-aware instructions to fire.
This lets us avoid needlessly going through the GPRs.  Consider:

    uint32x4_t test_mul(uint32x4_t a, uint32x4_t b) {
        return vmulq_n_u32(a, vaddvq_u32(b));
    }

We now generate:
    addv.4s  s1, v1
    mul.4s   v0, v0, v1[0]
instead of the previous:
    addv.4s  s1, v1
    fmov     w8, s1
    dup.4s   v1, w8
    mul.4s   v0, v1, v0

Also it extracts getCopyFromRegs helper function in SelectionDAGBuilder as we need to be able to customize type of the register exported from basic block during lowering of the gc.result.

44292e80ac Use a better name for compile unit labels.

Section->getLabelBeginName() makes it looks like they mark the start of the

While at it, switch to createTempSymbol to avoid collisions with labels

With this getLabelBeginName is dead, delete it.

14bd47ef85 DwarfAccelTable: Fix handling of hash collisions.
It turns out accelerator tables where totally broken if they contained
entries with colliding hashes. The failure mode is pretty bad, as it not
only impacted the colliding entries, but would basically make all the
entries after the first hash collision pointing in the wrong place.

The testcase uses the symbol names that where found to collide during a
clang build.

From a performance point of view, the patch adds a sort and a linear
walk over each bucket contents. While it has a measurable impact on the
accelerator table emission, it's not showing up significantly in clang
profiles (and I'd argue that correctness is priceless :-)).

55a060641f [CodeGen] Replace the reused stores' chain for extractelt expansion.
This fixes a subtle issue that was introduced in r205153.

When reusing a store for the extractelement expansion (to load directly
from it, inserting of going through the stack), later stores to the
same location might have overwritten the data we were expecting to
extract from.

To fix that, we need to explicitly replace the chain going out of the
reused store, so that later stores also have an explicit dependency on
the generated element-extracting loads, and can't clobber them.

cd5029d001 [SCEV] Unify getUnsignedRange and getSignedRange
Summary:
This removes some duplicated code, and also helps optimization: e.g. in
the test case added, `%idx ULT 128` in `@x` is not currently optimized
to `true` by `-indvars` but will be, after this change.

The only functional change in ths commit is that for add recurrences,
ScalarEvolution::getRange will be more aggressive -- computing the
unsigned (resp. signed) range for a SCEVAddRecExpr will now look at the
NSW (resp. NUW) bits and check for signed (resp. unsigned) overflow.
This can be a strict improvement in some cases (such as the attached
test case), and should be no worse in other cases.

d1232fa1c0 Fix line ending in test CodeGen/X86/pr22774.ll. NFC.
Also, replaced line with 'target triple' with flag -mtriple on the RUN line.
Removed the data layout string as it is not needed.

1428f080a8 Revert r231630 - Run LICM pass after loop unrolling pass.
As it broke llvm bootstrap.

8e120d80c3 Fix a bug in the LLParser where we failed to diagnose landingpads with non-constant clause operands.
Fixing this also exposed a related issue where the landingpad under construction was not
cleaned up when an error was raised, which would cause bad reference errors before the
error could actually be printed.

40e66277f7 [AArch64] Enable partial & runtime unrolling on cortex-a57
For inner one of nested loops, it is more likely to be a hot loop,
and the runtime check can be promoted out from patch 0001, so the
overhead is less, we can try a doubled threshold to unroll more loops.

994b4c784f Introduce runtime unrolling disable matadata and use it to mark the scalar loop from vectorization.
Runtime unrolling is an expensive optimization which can bring benefit
only if the loop is hot and iteration number is relatively large enough.
For some loops, we know they are not worth to be runtime unrolled.
The scalar loop from vectorization is one of the cases.

3836dd0315 Run LICM pass after loop unrolling pass.
Runtime unrollng will introduce a runtime check in loop prologue.
If the unrolled loop is a inner loop, then the proglogue will be inside
the outer loop. LICM pass can help to promote the runtime check out if
the checked value is loop invariant.

4c8f5afd99 InstCombine: fix fold "fcmp x, undef" to account for NaN
Summary:
See the two test cases.

; Can fold fcmp with undef on one side by choosing NaN for the undef

; Can fold fcmp with undef on both side
;   fcmp u_pred undef, undef -> true
;   fcmp o_pred undef, undef -> false
; because whatever you choose for the first undef
; you can choose NaN for the other undef
