Passes should never modify it, just use the const version. While there
reduce copying in LoopInterchange. No functional change intended.

James Y Knight 46f91c8457 Fix handling of the 'n' asm constraint with invalid operands.
It had accidently accepted a symbol+offset value (and emitted
incorrect code for it, keeping only the offset part) instead of
properly reporting the constraint as invalid.

Logan Chien 0a43abc9f8 ARM: Fix cttz expansion on vector types.
The 64/128-bit vector types are legal if NEON instructions are
available.  However, there was no matching patterns for @llvm.cttz.*()
intrinsics and result in fatal error.

This commit fixes the problem by lowering cttz to:
a. ctpop((x & -x) - 1)
b. width - ctlz(x & -x) - 1

Silviu Baranga a647c30f88 Cleanup after r241809 - remove uncessary call to std::sort
Summary:
The iteration order within a member of DepCands is deterministic
and therefore we don't have to sort the accesses within a member.
We also don't have to copy the indices of the pointers into a
vector, since we can iterate over the members of the class.

Ulrich Weigand ef5aa29e12 Support alternate attribute spelling __enable_if__
Attribute names usually support an alternate spelling that uses double
underscores before and after the attribute name, like e.g. attribute
((__aligned__)) for attribute ((aligned)). This is necessary to allow
use of attributes in system headers without polluting the name space.

However, for attribute ((enable_if)) that alternate spelling does not
work correctly. This is because of code in Parser::ParseGNUAttributeArgs
(ParseDecl.cpp) that specifically checks for the "enable_if" spelling
without allowing the alternate spelling.

Similar code in ParseDecl.cpp uses the normalizeAttrName helper to allow
both spellings. This patch adds use of that helper for the "enable_if"
check as well, which fixes attribute ((__enable_if__)).

Pavel Labath b6fddcd735 Avoid dependency on uuid.h in MacOSXDYLD
Summary:
r241964 has added a dependency on uuid.h, which (on linux at least) necessitates instalation of a
new package. Since the only thing we need from that file is uuid_t (and this is already defined
in UuidCompatibility.h), we can avoid this dependency by making this include __APPLE__ specific.
If in future, we need more from this library, we can revisit this decision.

Pavel Labath 77dc9569c6 Introduce a MainLoop class and switch llgs to use it
Summary:
This is the first part of our effort to make llgs single threaded. Currently, llgs consists of
about three threads and the synchronisation between them is a major source of latency when
debugging linux and android applications.

In order to be able to go single threaded, we must have the ability to listen for events from
multiple sources (primarily, client commands coming over the network and debug events from the
inferior) and perform necessary actions. For this reason I introduce the concept of a MainLoop.
A main loop has the ability to register callback's which will be invoked upon receipt of certain
events. MainLoopPosix has the ability to listen for file descriptors and signals.

For the moment, I have merely made the GDBRemoteCommunicationServerLLGS class use MainLoop
instead of waiting on the network socket directly, but the other threads still remain. In the
followup patches I indend to migrate NativeProcessLinux to this class and remove the remaining
threads.

Jingyue Wu 9a92d4fb04 [LSR] don't attempt to promote ephemeral values to indvars
Summary:
This at least saves compile time. I also encountered a case where
ephemeral values affect whether other variables are promoted, causing
performance issues. It may be a bug in LSR, but I didn't manage to
reduce it yet. Anyhow, I believe it's in general not worth considering
ephemeral values in LSR.

  undoing foo.
- Don't use inline assembly, we don't need it for these intrinsics.

Nico Weber 0e80816fe8 Fix lld tests with LLVM_ENABLE_THREADS disabled.
With LLVM_ENABLE_THREADS disabled, all the llvm code assumes that it runs on
a single thread and doesn't use any mutexes.  lld still spawned lots of threads
in that case and called into llvm, assuming that llvm is thread-safe.

As fix, let lld use only a single thread if LLVM_ENABLE_THREADS is disabled.
I left in all the mutexes in lld. That means lld is a bit slower than
necessary in single-thread mode, but that's probably worth the simpler code.

We don't need to track all formerly-canonical declarations of an entity; it's sufficient to track those ones for which no other formerly-canonical declaration was imported into the same module.

Davide Italiano a2275910a7 [Sema] If lvalue to rvalue reference cast is valid don't emit diagnostic.
In the test, y1 is not reference compatible to y2 and we currently assume
the cast is ill-formed so we emit a diagnostic. Instead, in order to honour
the standard, if y1 it's not reference-compatible to y2 then it can't be
converted using a static_cast, and a reinterpret_cast should be tried instead.
Richard Smith provided the correct interpretation of the standard and
explanation about the subtle difference between "can't be cast" and "the cast
is ill-formed". The former applies in this case.
