6a829ed9d4 Fix llvm-config to emit the linker flag for the combined shared object built by autoconfig/make instead of the individual components.
Summary:
When LLVM is configured to build shared libraries, CMake builds each component as it's own shared object, while autoconfig/make builds them statically and then links them all together to create a single shared object. This change adds compile time config flags to `llvm-config` so it can know whether LLVM's components are separated or not and act accordingly.

This fixes `llvm-config` instead of fixing the makefiles to behave like CMake because, AIUI, LLVM's autoconfig/make build system is on the way out anyway.

This change only affects `llvm-config` from builds that use autoconfig/make.

dbd8d4f056 AMDGPU: don't match vgpr loads for constant loads
Author: Dave Airlie <airlied@redhat.com>

In order to implement indirect sampler loads, we don't
want to match on a VGPR load but an SGPR one for constants,
as we cannot feed VGPRs to the sampler only SGPRs.

this should be applicable for llvm 3.7 as well.

4abd22ba6b [PeepholeOptimizer] Look through PHIs to find additional register sources
Reapply r242295 with fixes in the implementation.

- Teaches the ValueTracker in the PeepholeOptimizer to look through PHI
instructions.
- Add findNextSourceAndRewritePHI method to lookup into multiple sources
returnted by the ValueTracker and rewrite PHIs with new sources.

With these changes we can find more register sources and rewrite more
copies to allow coaslescing of bitcast instructions. Hence, we eliminate
unnecessary VR64 <-> GR64 copies in x86, but it could be extended to
other archs by marking "isBitcast" on target specific instructions. The
x86 example follows:

A:
  psllq %mm1, %mm0
  movd  %mm0, %r9
  jmp C

B:
  por %mm1, %mm0
  movd  %mm0, %r9
  jmp C

C:
  movd  %r9, %mm0
  pshufw  $238, %mm0, %mm0

Becomes:

A:
  psllq %mm1, %mm0
  jmp C

B:
  por %mm1, %mm0
  jmp C

C:
  pshufw  $238, %mm0, %mm0

541d079947 [ARM/AArch64] Fix cost model for interleaved accesses
Summary:
Fix the cost of interleaved accesses for ARM/AArch64.
We were calling getTypeAllocSize and using it to check
the number of bits, when we should have called
getTypeAllocSizeInBits instead.

This would pottentially cause the vectorizer to
generate loads/stores and shuffles which cannot
be matched with an interleaved access instruction.

No performance changes are expected for now since
matching/generating interleaved accesses is still
disabled by default.

9f141640b5 [TTI/CostModel] improve TTI::getGEPCost and use it in CostModel::getInstructionCost
Summary:
This patch updates TargetTransformInfoImplCRTPBase::getGEPCost to consider
addressing modes. It now returns TCC_Free when the GEP can be completely folded
to an addresing mode.

I started this patch as I refactored SLSR. Function isGEPFoldable looks common
and is indeed used by some WIP of mine. So I extracted that logic to getGEPCost.

Furthermore, I noticed getGEPCost wasn't directly tested anywhere. The best
testing bed seems CostModel, but its getInstructionCost method invokes
getAddressComputationCost for GEPs which provides very coarse estimation. So
this patch also makes getInstructionCost call the updated getGEPCost for GEPs.
This change inevitably breaks some tests because the cost model changes, but
nothing looks seriously wrong -- if we believe the new cost model is the right
way to go, these tests should be updated.

This patch is not perfect yet -- the comments in some tests need to be updated.
I want to know whether this is a right approach before fixing those details.

6db2ad6004 bugpoint: make the number of trim iterations a compile-time constant
Around 10 year ago Chris limited this code to a single iteration by just
dropping a break into the loop body. We now make the number of trim iterations
a compile time constant to be able to play with it and see if this can
improve the bugpoint results. We currently use with '3' still a small and
conservative value, but this can be adjusted in the future, if needed.

I tried to look for a trivial test case, but did not succeed yet.

5e7aab0de2 [llvm-dwarfump] Don't rely on global state, part 3.
Some tools used to rely on a global static variable to keep track of the 
return value for main(). I changed llvm-cxxdump to use exit(1)
and Rafael shortly after did the same with llvm-readobj. This is
(yet) another step towards the goal.

09fa5a537e [LAA] Begin moving the logic of generating checks out of addRuntimeCheck
Summary:
The goal is to start moving us closer to the model where
RuntimePointerChecking will compute and store the checks.  Then a client
can filter the check according to its requirements and then use the
filtered list of checks with addRuntimeCheck.

Before the patch, this is all done in addRuntimeCheck.  So the patch
starts to split up addRuntimeCheck while providing the old API under
what's more or less a wrapper now.

The new underlying addRuntimeCheck takes a collection of checks now,
expands the code for the bounds then generates the code for the checks.

I am not completely happy with making expandBounds static because now it
needs so many explicit arguments but I don't want to make the type
PointerBounds part of LAI.  This should get fixed when addRuntimeCheck
is moved to LoopVersioning where it really belongs, IMO.

Audited the assembly diff of the testsuite (including externals).  There
is a tiny bit of assembly churn that is due to the different order the
code for the bounds is expanded now
(MultiSource/Benchmarks/Prolangs-C/bison/conflicts.s and with LoopDist
on 456.hmmer/fast_algorithms.s).

7b0238cdc1 [LoopUnswitch] Improve loop unswitch pass to find trivial unswitch conditions more effectively
Summary:
This patch improves trivial loop unswitch. 

The current trivial loop unswitch only checks if loop header's terminator contains a trivial unswitch condition. But if the loop header only has one reachable successor (due to intentionally or unintentionally missed code simplification), we should consider the successor as part of the loop header. Therefore, instead of stopping at loop header's terminator, we should keep traversing its successors within loop until reach a *real* conditional branch or switch (whose condition can not be constant folded). This change will enable a single -loop-unswitch pass to unswitch multiple trivial conditions (unswitch one trivial condition could open opportunity to unswitch another one in the same loop), while the old implementation can unswitch only one per pass.

cbfbb3ee4c DI/Verifier: Fix argument bitrot in DILocalVariable
Add a verifier check that `DILocalVariable`s of tag
`DW_TAG_arg_variable` always have a non-zero 'arg:' field, and those of
tag `DW_TAG_auto_variable` always have a zero 'arg:' field.  These are
the only configurations that are properly understood by the backend.

(Also, fix the bad examples in LangRef and test/Assembler, and fix the
bug in Kaleidoscope Ch8.)

A large number of testcases seem to have bitrotted their way forward
from some ancient version of the debug info hierarchy that didn't have
`arg:` parameters.  If you have out-of-tree testcases that start failing
in the verifier and you don't care enough to get the `arg:` right, you
may have some luck just calling:

    sed -e 's/, arg: 0/, arg: 1/'

or some such, but I hand-updated the ones in tree.

These always empty fields are gone, so don't test that they're empty.

e5f2fce18a DI: Remove unnecessary DICompositeTypeBase
Remove unnecessary and confusing common base class for `DICompositeType`
and `DISubroutineType`.

While at a high-level `DISubroutineType` is a sort of composite of other
types, it has no shared code paths, and its fields are completely
disjoint.  This relationship was left over from the old debug info
hierarchy.

24b6acf971 DI: Simplify DebugInfoFinder::processType(), NFC
Handle `DISubroutineType` up-front rather than as part of a branch for
`DICompositeTypeBase`.  The only shared code path was looking through
the base type, but `DISubroutineType` can never have a base type.

This also removes the last use of `DICompositeTypeBase`, since we can
strengthen the cast to `DICompositeType`.

88c307a010 AsmPrinter: Use DICompositeType in updateAcceleratorTables(), NFC
`DISubroutineType` is impossible at this `dyn_cast` site, since we're
only dealing with named types and `DISubroutineType` cannot be named.
Strengthen the `dyn_cast` to `DICompositeType`.

dfe0e536ee MIR Serialization: Serialize the simple virtual register allocation hints.
This commit serializes the virtual register allocations hints of type 0.
These hints specify the preferred physical registers for allocations.

7b464ae8b9 DI: Remove DIDerivedTypeBase
Remove an unnecessary (and confusing) common subclass for
`DIDerivedType` and `DICompositeType`.  These classes aren't really
related, and even in the old debug info hierarchy, there was a
long-standing FIXME to separate them.

b2c91c5ecd Verifier: Sink filename check into visitMDCompositeType(), NFC
We really only want to check this for unions and classes (all the other
tags have been ruled out), so simplify the check and move it to the
right place.

cb21505064 Verifier: Remove unnecessary references to DW_TAG_subroutine_type, NFC
Remove unnecessary references to `DW_TAG_subroutine_type` in
`visitDICompositeType()` and `visitDIDerivedTypeBase()`, since
`visitDISubroutineType()` doesn't call either of those (and shouldn't,
since subroutine types are really quite special).
