some other thread being able to mess up the list by deleting/disabline one of its
locations in the process of doing so.

Richard Trieu 6093d143c5 Disable -Wpessimizing-move and -Wredundant-move in template instantiations.
Dependent types can throw off the analysis for these warnings, possibly giving
conflicting warnings and fix-its.  Disabling the warning in template
instantiations will prevent this problem, and will still catch the
non-dependent cases in templates.

Rui Ueyama eb26e1d03c COFF: Fix SECREL and SECTION relocations.
SECREL should sets the 32-bit offset of the target from the beginning
of *target's* output section. Previously, the offset from the beginning
of source's output section was used instead.

SECTION means the target section's index, and not the source section's
index. This patch fixes that issue too.

Bill Schmidt 42ddd71120 [PPC] Fix PR24216: Don't generate splat for misaligned shuffle mask
Given certain shuffle-vector masks, LLVM emits splat instructions
which splat the wrong bytes from the source register.  The issue is
that the function PPC::isSplatShuffleMask() in PPCISelLowering.cpp
does not ensure that the splat pattern found is requesting bytes that
are aligned on an EltSize boundary.  This patch detects this situation
as not a valid splat mask, resulting in a permute being generated
instead of a splat.

Patch and test case by Tyler Kenney, cleaned up a bit by me.

This is a simple bug fix that would be good to incorporate into 3.7.

Tobias Grosser 80e237bd53 Do not detect scops that are delinearized to arrays with "undef" size
Such codes are not interesting to optimize and most likely never appear in the
normal compilation flow. However, they show up during test case reduction with
bugpoint and trigger -- without this change -- an assert in
polly::MemoryAccess::foldAccess(). It is better to detect them in
ScopDetection itself and just bail out.

Pavel Labath 6e4f19d440 [LLGS] Spawned process handling cleanup
Summary:
This commit moves the m_spawned_pids member from the common LLGS/Platform class to the plaform
specific part. This enables us to remove LLGS code, which was attempting to manage the
m_spawned_pids contents, but at the same time making sure, there is only one debugged process. If
we ever want to do multi-process debugging, we will probably want to replace this with a set of
NativeProcessProtocolSP anyway. The only functional change is that support for
qKillSpawnedProcess packet is removed from LLGS, but this was not used there anyway (we have the
k packet for that).

Jason Molenda 752e1e833b When debugserver fails to attach to a process on a Darwin
system, make a couple of additional checks to see if the
attach was denied via the System Integrity Protection that
is new in Mac OS X 10.11.  If so, return a special E87
error code to indicate this to lldb.

Up in lldb, if we receive the E87 error code, be specific
about why the attach failed.

Also detect the more common case of general attach failure
and print a better error message than "lost connection".

I believe this code will all build on Mac OS X 10.10 systems.
It may not compile or run on earlier versions of the OS.
None of this should build on other non-darwin systems.

Jason Molenda 6ab659a922 First part of an attempt to indicate to the user when they are
debugging optimized code.  Adds new methods on Function/SBFunction
to query whether a given function is optimized.  Adds a new
function.is-optimized format entity and changes the default 
frame-format to append "[opt]" if the function was built with
optimization.

The only indication that a binary was built with optimization
that we have right now is the presence of the DW_AT_APPLE_optimized
attribute (DW_FORM_flag value 1) in the DW_TAG_compile_unit.
The absence of this flag may mean that the compile_unit was not
compiled with optimization, or it may mean that the producer 
does not generate this attribute.

Currently this only works for dSYM debugging.  When we create
the CompileUnit with dwarf-in-.o-file debugging we don't have
the attribute value yet so it's not set.  I need to find the
flag value when we do start to read the .o file DWARF and 
set the CompileUnit's status at that point - but haven't 
done it yet.

I'm also going to add a mechanism for issuing warnings to users
such that they're only issued once in a debug session and 
there is away for users to suppress these warnings altogether
via .lldbinit file settings.  But I want to get this changeset
committed now that it's at a useful state.

Eric Fiselier 7eb30deff1 [libcxx] Cleanup CMake configuration and integrate with LLVM
Summary:
This patch contains the following changes:

1. Require that libc++ can find a LLVM source directory. This is done the same way as `libc++abi` currently does.
2. Cleanup ugly configuration code in CMakeLists.txt by using `add_flags`, `add_flags_if`, and `add_flags_if_supported` macros.

The goals for this patch are:

1. Help libc++ be more consistent with how LLVM handles CMake options (see PR23670 PR23671).
2. Make it easier to use sanitizers using the `LLVM_USE_SANITIZER` option.
3. Make libc++'s CMakeLists.txt file easier to understand and change.
4. Move towards allowing libc++ to create Sphinx documentation (see http://efcs.ca/libcxx-docs). 
5. Move towards allowing  libc++ to use other LLVM utilities such as `not` and `FileCheck`.

Sanjoy Das cfe41f050c [Statepoints] Let patchable statepoints have a symbolic call target.
Summary:
As added initially, statepoints required their call targets to be a
constant pointer null if ``numPatchBytes`` was non-zero.  This turns out
to be a problem ergonomically, since there is no way to mark patchable
statepoints as calling a (readable) symbolic value.

This change remove the restriction of requiring ``null`` call targets
for patchable statepoints, and changes PlaceSafepoints to maintain the
symbolic call target through its transformation.

Sanjay Patel 133e68b45c ignore duplicate divisor uses when transforming into reciprocal multiplies (PR24141)
PR24141: https://llvm.org/bugs/show_bug.cgi?id=24141
contains a test case where we have duplicate entries in a node's uses() list.

After r241826, we use CombineTo() to delete dead nodes when combining the uses into
reciprocal multiplies, but this fails if we encounter the just-deleted node again in
the list.

The solution in this patch is to not add duplicate entries to the list of users that
we will subsequently iterate over. For the test case, this avoids triggering the
combine divisors logic entirely because there really is only one user of the divisor.

This fix was suggested as part of D11345 and is part of fixing PR24141.

There is no NFC-intended other than that.
