Rafael Espindola a092f17580 Don' try to make sections in comdats SHF_MERGE.
Parts of llvm were not expecting it and we wouldn't print
the entity size of the section.

Given what comdats are used for, having SHF_MERGE sections would be
just a small improvement, so just disable it for now.

Fixes pr22463.

DeLesley Hutchins 3c355aa24d Thread Safety Analysis: support adopting of locks, as implemented in
std::lock_guard.  If EXCLUSIVE_LOCKS_REQUIRED is placed on the constructor of
a SCOPED_LOCKABLE class, then that constructor is assumed to adopt the lock;
e.g. the lock must be held on construction, and will be released on destruction.

Tobias Grosser 52a25237d8 Import isl(+imath) as an external library into Polly
With this patch Polly is always GPL-free (no dependency on GMP any more). As a
result, building and distributing Polly will be easier. Furthermore, there is no
need to tightly coordinate isl and Polly releases anymore.

We import isl b3e0fa7a05d as well as imath 4d707e5ef2. These are the git
versions Polly currently was tested with when using utils/checkout_isl.sh. The
imported libraries are both MIT-style licensed.

We build isl and imath with -fvisibility=hidden to avoid clashes in case other
projects (such as gcc) use conflicting versions of isl. The use of imath can
temporarily reduce compile-time performance of Polly. We will work on
performance tuning in tree.

Patches to isl should be contributed first to the main isl repository and can
then later be reimported to Polly.

This patch is also a prerequisite for the upcoming isl C++ interface.

Tom Stellard c7e448c92e R600/SI: Make more store operations legal
v2i32, i32, trunc i32 to i16, and truc i32 to i8 stores are legal for
all address spaces.  We had marked them as custom in order to lower
them for the private address space, but this is no longer necessary.

This enables lowering of misaligned stores of these types in the
DAGLegalizer.

Tom Stellard 071ec90b68 StructurizeCFG: Use a reverse post-order traversal
We were previously doing a post-order traversal and operating on the
list in reverse, however this would occasionaly cause backedges for
loops to be visited before some of the other blocks in the loop.

We know use a reverse post-order traversal, which avoids this issue.

The reverse post-order traversal is not completely ideal, so we need
to manually fixup the list to ensure that inner loop backedges are
visited before outer loop backedges.

David Blaikie 4d52443c0e DebugInfo: Attribute cleanup code to the end of the scope, not the end of the function.
Now if you break on a dtor and go 'up' in your debugger (or you get an
asan failure in a dtor) during an exception unwind, you'll have more
context. Instead of all dtors appearing to be called from the '}' of the
function, they'll be attributed to the end of the scope of the variable,
the same as the non-exceptional dtor call.

This doesn't /quite/ remove all uses of CurEHLocation (which might be
nice to remove, for a few reasons) - it's still used to choose the
location for some other work in the landing pad. It'd be nice to
attribute that code to the same location as the exception calls within
the block and to remove CurEHLocation.

Jordan Rose cb5386cbfc [analyzer] RetainCountChecker: be forgiving when ivars are accessed directly.
A refinement of r204730, itself a refinement of r198953, to better handle
cases where an object is accessed both through a property getter and
through direct ivar access. An object accessed through a property should
always be treated as +0, i.e. not owned by the caller. However, an object
accessed through an ivar may be at +0 or at +1, depending on whether the
ivar is a strong reference. Outside of ARC, we don't always have that
information.

The previous attempt would clear out the +0 provided by a getter, but only
if that +0 hadn't already participated in other retain counting operations.
(That is, "self.foo" is okay, but "[[self.foo retain] autorelease]" is
problematic.) This turned out to not be good enough when our synthesized
getters get involved.

This commit drops the notion of "overridable" reference counting and instead
just tracks whether a value ever came from a (strong) ivar. If it has, we
allow one more release than we otherwise would. This has the added benefit
of being able to catch /some/ overreleases of instance variables, though
it's not likely to come up in practice.

We do still get some false negatives because we currently throw away
refcount state upon assigning a value into an ivar. We should probably
improve on that in the future, especially once we synthesize setters as
well as getters.

Alexey Samsonov a511cdd247 Allow to specify multiple -fsanitize-blacklist= arguments.
Summary:
Allow user to provide multiple blacklists by passing several
-fsanitize-blacklist= options. These options now don't override
default blacklist from Clang resource directory, which is always
applied (which fixes PR22431).

-fno-sanitize-blacklist option now disables all blacklists that
were specified earlier in the command line (including the default
one).

This change depends on http://reviews.llvm.org/D7367.

Alexey Samsonov b9b8027cee SpecialCaseList: Add support for parsing multiple input files.
Summary:
This change allows users to create SpecialCaseList objects from
multiple local files. This is needed to implement a proper support
for -fsanitize-blacklist flag (allow users to specify multiple blacklists,
in addition to default blacklist, see PR22431).

DFSan can also benefit from this change, as DFSan instrumentation pass now
accepts ABI-lists both from -fsanitize-blacklist= and -mllvm -dfsan-abilist flags.

Go bindings are fixed accordingly.

correctly. __try and __finally are keywords if `LangOpts.MicrosoftExt` is set,
so this turns this on.  This also enables a few other keywords, but it
shouldn't overly perturb regular clang-format operation.  __except is a
context-sensitive keyword, so `AdditionalKeywords` needs to be passed around to
a few more places.
