Unpredicated FP-multiply of SVE vector with a vector-element given by
vector[index], for example:

  fmul z0.s, z1.s, z2.s[0]

which performs an unpredicated FP-multiply of all 32-bit elements in

This patch adds restricted register classes for SVE vectors:
  ZPR_3b (only z0..z7 are allowed)  - for indexed vector of 16/32-bit elements.
  ZPR_4b (only z0..z15 are allowed) - for indexed vector of 64-bit elements.

Sanjay Patel 3074b9e53f [InstCombine] fold shuffle-with-binop and common value
This is the last significant change suggested in PR37806:
https://bugs.llvm.org/show_bug.cgi?id=37806#c5
...though there are several follow-ups noted in the code comments 
in this patch to complete this transform.

It's possible that a binop feeding a select-shuffle has been eliminated 
by earlier transforms (or the code was just written like this in the 1st 
place), so we'll fail to match the patterns that have 2 binops from: 
D48401, 
D48678, 
D48662, 
D48485.

In that case, we can try to materialize identity constants for the remaining
binop to fill in the "ghost" lanes of the vector (where we just want to pass 
through the original values of the source operand).

I added comments to ConstantExpr::getBinOpIdentity() to show planned follow-ups. 
For now, we only handle the 5 commutative integer binops (add/mul/and/or/xor).

Bjorn Pettersson 8dd6cf711f [DebugInfo] Corrections for salvageDebugInfo
Summary:
When salvaging a dbg.declare/dbg.addr we should not add
DW_OP_stack_value to the DIExpression
(see test/Transforms/InstCombine/salvage-dbg-declare.ll).

Consider this example
  %vla = alloca i32, i64 2
  call void @llvm.dbg.declare(metadata i32* %vla, metadata !1, metadata !DIExpression())

Instcombine will turn it into
  %vla1 = alloca [2 x i32]
  %vla1.sub = getelementptr inbounds [2 x i32], [2 x i32]* %vla, i64 0, i64 0
  call void @llvm.dbg.declare(metadata [2 x i32]* %vla1.sub, metadata !19, metadata !DIExpression())

If the GEP can be eliminated, then the dbg.declare will be salvaged
and we should get
  %vla1 = alloca [2 x i32]
  call void @llvm.dbg.declare(metadata [2 x i32]* %vla1, metadata !19, metadata !DIExpression())

The problem was that salvageDebugInfo did not recognize dbg.declare
as being indirect (%vla1 points to the value, it does not hold the
value), so we incorrectly got
  call void @llvm.dbg.declare(metadata [2 x i32]* %vla1, metadata !19, metadata !DIExpression(DW_OP_stack_value))

I also made sure that llvm::salvageDebugInfo and
DIExpression::prependOpcodes do not add DW_OP_stack_value to
the DIExpression in case no new operands are added to the
DIExpression. That way we avoid to, unneccessarily, turn a
register location expression into an implicit location expression
in some situations (see test11 in test/Transforms/LICM/sinking.ll).

James Henderson b427d4eced [ELF] Don't create empty output section for unreferenced PROVIDEs
LLD removes empty output sections otherwise specified in the linker
script. Prior to this change however, if section descriptions included
ANY kind of symbol assignment, then the consequent output section would
not be removed, even if the assignment was marked with PROVIDE and not
actually triggered (i.e. the symbol was never referenced). This change
modifies the isDiscarable function to ignore such directives when
determining whether a section should be discarded, in keeping with
bfd's behaviour. Symbol assignments that do result in a symbol
definition will continue to result in a kept section (this is not
actually the same as bfd's behaviour, but it is simpler, and probably
makes more sense).

Chandler Carruth 3897ded691 [PM/LoopUnswitch] Fix PR37651 by correctly invalidating SCEV when
unswitching loops.

Original patch trying to address this was sent in D47624, but that
didn't quite handle things correctly. There are two key principles used
to select whether and how to invalidate SCEV-cached information about
loops:

1) We must invalidate any info SCEV has cached before unswitching as we
   may change (or destroy) the loop structure by the act of unswitching,
   and make it hard to recover everything we want to invalidate within
   SCEV.

2) We need to invalidate all of the loops whose CFGs are mutated by the
   unswitching. Notably, this isn't the *entire* loop nest, this is
   every loop contained by the outermost loop reached by an exit block
   relevant to the unswitch.

And we need to do this even when doing trivial unswitching.

I've added more focused tests that directly check that SCEV starts off
with imprecise information and after unswitching (and simplifying
instructions) re-querying SCEV will produce precise information. These
tests also specifically work to check that an *outer* loop's information
becomes precise.

However, the testing here is still a bit imperfect. Crafting test cases
that reliably fail to be analyzed by SCEV before unswitching and succeed
afterward proved ... very, very hard. It took me several hours and
careful work to build these, and I'm not optimistic about necessarily
coming up with more to cover more elaborate possibilities. Fortunately,
the code pattern we are testing here in the pass is really
straightforward and reliable.

Thanks to Max Kazantsev for the initial work on this as well as the
review, and to Hal Finkel for helping me talk through approaches to test
this stuff even if it didn't come to much.

Sam McCall 3f0243fdaf [clangd] Incorporate transitive #includes into code complete proximity scoring.
Summary:
We now compute a distance from the main file to the symbol header, which
is a weighted count of:
 - some number of #include traversals from source file --> included file
 - some number of FS traversals from file --> parent directory
 - some number of FS traversals from parent directory --> child file/dir
This calculation is performed in the appropriate URI scheme.

This means we'll get some proximity boost from header files in main-file
contexts, even when these are in different directory trees.

This extended file proximity model is not yet incorporated in the index
interface/implementation.

Summary:
This patch is the first in a series of patches related to the [[ http://lists.llvm.org/pipermail/llvm-dev/2018-June/123883.html | RFC - A new dominator tree updater for LLVM ]].

This patch introduces the DomTreeUpdater class, which provides a cleaner API to perform updates on available dominator trees (none, only DomTree, only PostDomTree, both) using different update strategies (eagerly or lazily) to simplify the updating process.

—Prior to the patch—

   - Directly calling update functions of DominatorTree updates the data structure eagerly while DeferredDominance does updates lazily.
   - DeferredDominance class cannot be used when a PostDominatorTree also needs to be updated.
   - Functions receiving DT/DDT need to branch a lot which is currently necessary.
   - Functions using both DomTree and PostDomTree need to call the update function separately on both trees.
   - People need to construct an additional DeferredDominance class to use functions only receiving DDT.

Erik Pilkington 988a16af92 Revert r336159, r336157. Some bots failed on qualified std::max_align_t, and other on unqualified max_align_t.
I'll take another stab at this tomorrow. Any ideas for fixing this would be appreciated!

Chandler Carruth f814ad8932 [Support] Fix llvm::unique_function when building with GCC 4.9 by
introducing llvm::trivially_{copy,move}_constructible type traits.

This uses a completely portable implementation of these traits provided
by Richard Smith. You can see it on compiler explorer in all its glory:

  https://godbolt.org/g/QEDZjW

I have transcribed it, clang-formatted it, added some comments, and made
the tests fit into a unittest file.

I have also switched llvm::unique_function over to use these new, much
more portable traits. =D

Hopefully this will fix the build bot breakage from my prior commit.

Teresa Johnson f8182f1aef [ThinLTO] Fix printing of aliases for distributed backend indexes
Summary:
When we import an alias (which will import a copy of the aliasee), but
aren't going to import the aliasee directly, the distributed backend
index will not contain the aliasee summary. Handle this in the summary
assembly printer by printing "null" as the aliasee.
