Alexander Potapenko d5802fe548 Make signal-related functions use __sanitizer_* structures instead of __sanitizer_kernel_* ones.
Also rename internal_sigaction() into internal_sigaction_norestorer(), as this function doesn't fully
implement the sigaction() functionality on Linux.

This change is a part of refactoring intended to have common signal handling behavior in all tools.

Chandler Carruth c12224cb93 [vectorizer] Tweak the way we do small loop runtime unrolling in the
loop vectorizer to not do so when runtime pointer checks are needed and
share code with the new (not yet enabled) load/store saturation runtime
unrolling. Also ensure that we only consider the runtime checks when the
loop hasn't already been vectorized. If it has, the runtime check cost
has already been paid.

I've fleshed out a test case to cover the scalar unrolling as well as
the vector unrolling and comment clearly why we are or aren't following
the pattern.

Logan Chien 22747e621e Remove default function template argument from the header.
GCC will treat the default function template arguments as a
compilation error if C++0x is not enabled.

This commit workaround the compilation error by moving the
SFINAE check to function argument instead of the template
argument.

Bob Wilson 055a0b4ca2 Fix a bug in gcov instrumentation introduced by r195513. <rdar://15930350>
The entry block of a function starts with all the static allocas. The change
in r195513 splits the block before those allocas, which has the effect of
turning them into dynamic allocas. That breaks all sorts of things. Change to
split after the initial allocas, and also add a comment explaining why the
block is split.

Manman Ren 413a6cb42b This patch teaches the DAGCombiner how to fold insert_subvector nodes
when the input is a concat_vectors and the insert replaces one of the
concat halves:

Lower half: fold (insert_subvector (concat_vectors X, Y), Z) ->
(concat_vectors Z, Y)
Upper half: fold (insert_subvector (concat_vectors X, Y), Z) ->
(concat_vectors X, Z)

This can be seen with the following IR:

define <8 x float> @lower_half(<4 x float> %v1, <4 x float> %v2, <4 x
float> %v3) {
  %1 = shufflevector <4 x float> %v1, <4 x float> %v2, <8 x i32> <i32
0, i32 1, i32 2, i32 3, i32 4, i32 5, i32 6, i32 7>
  %2 = tail call <8 x float> @llvm.x86.avx.vinsertf128.ps.256(<8 x
float> %1, <4 x float> %v3, i8 0)

The vinsertf128 intrinsic is converted into an insert_subvector node
in SelectionDAGBuilder.cpp.

Using AVX, without the patch this generates two vinsertf128 instructions:

vinsertf128 $1, %xmm1, %ymm0, %ymm0
vinsertf128 $0, %xmm2, %ymm0, %ymm0

With the patch this is optimized into:

vinsertf128 $1, %xmm1, %ymm2, %ymm0

Ben Langmuir 332aafede3 Fix autolinking when modules are imported in pch files
Add the ImportDecl to the set of interesting delcarations that are
deserialized eagerly when an AST file is loaded (rather than lazily like
most decls). This is required to get auto linking to work when there is
no explicit import in the main file. Also resolve a FIXME to rename
'ExternalDefinitions', since that is only one of the things that need eager
deserialization. The new name is 'EagerlyDeserializedDecls'. The corresponding
AST bitcode is also renamed.

Manman Ren 4ece7452ba PGO branch weight: update edge weights in SelectionDAGBuilder.
When converting from "or + br" to two branches, or converting from
"and + br" to two branches, we correctly update the edge weights of
the two branches.

The previous attempt at r200431 was reverted at r200434 because of
two testing case failures. I modified my patch a little, but forgot
to re-run "make check-all".

Testing case CodeGen/ARM/lsr-unfolded-offset.ll is updated because of
the patch's impact on branch probability which causes changes in
spill placement.

These should end up (in ELF) as R_X86_64_32S relocs, not R_X86_64_32.
