This was only present for SI before.
Cayman may still be missing, but I am unable to test that currently.

Summary:
http://llvm.org/bugs/show_bug.cgi?id=20892
Add support of C-style formatting enabling/disabling directives. Now the following two styles are supported:
// clang-format on
/* clang-format on */
The flexibility in comments (support of extra spaces and/or slashes, etc.) is deliberately avoided to simplify search in large code bases.

This patch fixes the bad argument that GAS accepted but the IAS didn't,
ie. {#0x20}, moving it to {0x20} which both accept. It also makes the
ARMv7+ save/restore correct by using VFP instructions rather than old
co-processor ones.
Fixes PR20529.

David Blaikie's commits r217563 & r217564, which added shared_ptr to the
CostPool have fixed some memory leak issues exposed by the PBQP with
coalescing constraints.
The sanitizer bot was failing because of those leaks. Now that the leaks
are gone, we can reenable the aarch64/pbqp test.

The provided base must also be a multiple of the system's page size, which is a
reasonable enough demand.
Also check the other diagnostics more thoroughly.

We used to crash processing any relevant @llvm.assume on a 32-bit target
(because we'd ask SE to subtract expressions of differing types). I've copied
our 'simple.ll' test, but with the data layout from arm-linux-gnueabihf to get
some meaningful test coverage here.

The existing system linkers on Darwin and Linux are called "ld". We'd like to
eventually drop in lld as "ld" and have it just work. But lld is a universal
linker that requires the first option to be -flavor to know which command line
mode to emulate (gnu or darwin).
This change tests if argv[0] is "ld" and if so, if the tool was built on MacOSX
then assume the darwin flavor otherwise the gnu flavor. There are two test
cases which copy lld to "ld" and then run it. One for darwin and one for linux.

Leveraging both intrusive shared_ptr-ing (std::enable_shared_from_this)
and shared_ptr<T>-owning-U (to allow external users to hold
std::shared_ptr<CostT> while keeping the underlying PoolEntry alive).
The intrusiveness could be removed if we had a weak_set that implicitly
removed items from the set when their underlying data went away.
This /might/ fix an existing memory leak reported by LeakSanitizer in
r217504.

Need to convert the 64 element offset into bytes, not just the element
size like the normal case instructions.
Noticed by inspection. This can't be hit now because
st64 instructions aren't emitted during instruction selection,
and the post-RA scheduler isn't enabled.

We may as well just use Symbolizer::GetOrInit() in all the cases.
Don't call Symbolizer::Get() early in tools initialization: these days
it doesn't do any important setup work, and we may as well create the
symbolizer the first time it's actually needed.

Numerous changes, including:
* Changed the way variables and instructions are handled in basic blocks to
be more efficient.
* Eliminated SExprRef.
* Simplified futures.
* Fixed documentation.
* Compute dominator and post dominator trees.

1. We were hitting the NextIsPrevious assertion because we were trying
to merge decl chains that were independent of each other because we had
no Sema object to allow them to find existing decls. This is fixed by
delaying loading the "preloaded" decls until Sema is available.
2. We were trying to get identifier info from an annotation token, which
asserts. The fix is to special-case the module annotations in the
preprocessed output printer.
Fixed in a single commit because when you hit 1 you almost invariably
hit 2 as well.

Adds the qThreadStopInfo RSP command for llgs and includes a test that
verifies both debugserver and llgs respond with something reasonable
on a multithreaded app.

With this a DataLayoutPass can be reused for multiple modules.
Once we have doInitialization/doFinalization, it doesn't seem necessary to pass
a Module to the constructor.
Overall this change seems in line with the idea of making DataLayout a required
part of Module. With it the only way of having a DataLayout used is to add it
to the Module.

actually different. Fixes a surprising link error with nodejs on rpi,
where armv6-netbsd-eabihf turned into armv5e-netbsd-eabihf, which
doesn't lacks the necessary VFP support.

The routine that determines an alignment given some SCEV returns zero if the
answer is unknown. In a case where we could determine the increment of an
AddRec but not the starting alignment, we would compute the integer modulus by
zero (which is illegal and traps). Prevent this by returning early if either
the start or increment alignment is unknown (zero).

FIx a problem reported by Jakub Jelinek: don't do early-exit from fatal
UBSan handlers: even if source location is disabled (i.e. acquired by
some other thread), we should continue the execution to make sure that:
a) some thread will print the error report before calling Die().
b) handler marked as noreturn will indeed not return.
Explicitly add "Die()" calls at the end of all fatal handlers to be
sure UBSan handlers don't introduce UB themselves.
