libpthread is weird:
/lib/x86_64-linux-gnu/libpthread.so.0:000000000000b9b0 T pthread_cond_init@@GLIBC_2.3.2
/lib/x86_64-linux-gnu/libpthread.so.0:000000000000c720 T pthread_cond_init@GLIBC_2.2.5
let's do it with @@ for now
we can always introduce more macros parameters later

Select condition shadow was being ignored resulting in false negatives.
This change OR-s sign-extended condition shadow into the result shadow.

This changes the SelectionDAG nodes from ISD::INTRINSIC_W_CHAIN to
ISD::INTRINSIC_WO_CHAIN which enables easy lowering to equivalent SelectionDAG
nodes (e.g. __builtin_msa_sub_w -> ISD::SUB) in future patches since nodes
such as ISD::SUB do not have a chain.
It also corrects an obvious mistake, namely that the subtract intrinsics were
marked as being commutative.
As per a similar change in r189106
(http://llvm.org/viewvc/llvm-project?rev=189106&view=rev) there isn’t a new
testcase in this patch since the existing tests should test the intrinsics to
the same standard and the best I can do for a testcase would be a fragile
pass/maybe test of whether memory operations can (and do) cross the intrinsic.

been an oversight, as it definitely works. Every test which changed had
the const written on the LHS of the auto already.
Notably, this also makes things like cpp11-migrate's formation of 'const
auto &' variables much more familiar.
Yes, many people feel that 'const' and other qualifiers belong on the
RHS of the type. I'm not going to argue about that because Clang already
*overwhelming* places the qualifiers on the LHS when it can and on the
RHS when it must. We shouldn't diverge for auto. We should add a tool to
clang-tidy that fixes this in either direction, and then wire up
clang-tidy to tools like cpp11-migrate to fix their placement after
transforms.

What we really want is to enable Swift by default for *v7s triples (and there already seems to be some logic which attempts to do that). In that case the iOS version doesn't matter.

Summary:
Store first and last newline position in the token text for string literals and
comments to avoid doing .find('\n') for each possible solution.

Add a wrapper for the clone syscall for use in StopTheWorld. We
implement it only for x86_64, so stop building StopTheWorld for other platforms
(no one uses it outside x86_64 anyway).
See https://code.google.com/p/address-sanitizer/issues/detail?id=214 for why we
can't use the glibc clone() wrapper.

This is an improved version of r186498. It enables ExprEngine to reason about
temporary object destructors. However, these destructor calls are never
inlined, since this feature is still broken. Still, this is sufficient to
properly handle noreturn temporary destructors.
Now, the analyzer correctly handles expressions like "a || A()", and executes the
destructor of "A" only on the paths where "a" evaluted to false.
Temporary destructor processing is still off by default and one has to
explicitly request it by setting cfg-temporary-dtors=true.

Summary:
This change makes races between updates of thread-local stats and
merging all the thread-local stats together less harmful.

fallback syntax used when we fail to find a '.clang-format' file. Adjust
variable names appropriately.
Update the editor integration pieces that specify a '-style' option to
specify it as '-style=file'. I left the functionality in place because
even if the preferred method is to use '.clang-format' files, this way
if someone needs to clobber the style in their editor we show how to do
so in these examples.
Also check in a '.clang-format' file for Clang to ensure that separate
checkouts and builds of Clang from LLVM can still get the nice
formatting. =] This unfortunately required nuking the test for the
absence of a '.clang-format' file as now the directory happening to be
under your clang source tree will cause there to always be a file. ;]
