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. ;]

This patch implements vector support for select instruction and adds specific vector instructions : shuffle and insertelement. (tests are also included)
and functions lle_X_memset, lle_X_memcpy added.

printing routine. This is made harder to see due to the surprising
formatting, inconsistent brace usage, and repeated conditions that all
test the same thing.
The only "consequence" of this bug is re-assigning 'str' to an empty
string when computing the error string for an error number of 0 in the
event of a non-GNU strerror_r routine. So, nothing to see here other
than cleanup. It did help me find PR17055 in clang-format though.

Iterator of std::vector may be implemented as a raw pointer. In
this case ADL does not find the find() function in the std namespace.
For example, this is the case with STDCXX implementation of vector.

part of getting started with LLVM.
The LLVM getting started document is in woeful need of attention. I may
get to some of this, but some random notes for folks interested:
1) We need to separate the getting started steps for folks who are
interested in the core LLVM libs and nothing else, folks interested
in a nifty C++ toolchain and nothing else, and folks interested in
both.
2) We should include documentation for both release archives, svn, and
git in equal portion, and we should document all of the various
repositories of interest: llvm, clang, clang-tools-extra,
compiler-rt, lld, libcxx, test-suite.
3) We should document the CMake build. We should probably document the
CMake build first, and give a fall-back set of docs for the Makefile
build for the use cases where that is still the preferred solution.
This would more closely match the use cases that folks in the open
source community are likely to have, and would remove a point of
discrepancy between Linux, Windows, and Mac instructions.
4) Probably a ton of other modernization stuff that I've not thought of
here.
Anyways, if anyone at all is interested, please help clean up this
document. It is much needed.

don't exist in libc. This is really not the right way to solve this problem;
but it's not clear to me at this time exactly what is the right way.
If we create stubs here, they will cause link errors because these functions
do not exist in libc.

The existing code missed some edge cases when e.g. we're going to emit sqrtf but
only the availability of sqrt was checked. This happens on odd platforms like
windows.

This adds an API to the LinkingContext for flavors to add Internal files
containing atoms that need to appear in the YAML output as well, when -emit-yaml
switch is used.
Flavors can add more internal files for other options that are needed.

There was one case that we could hit a DebugValue where I didn't think
to check. DebugValues are evil. No checkinable test case, sorry. It's
an obvious fix.

InitializedEntity::EntityKind as an index for one of its %select. Over time,
EntityKind has been expanded, but the diagnostic text has not been updated.
This adds additional text to the %select to cover the new enum values. A
comment has been added to the end of the enum regarding this situation. This
fixes the crasher in PR17043.

Here are a few miscellaneous things to tidy up the PPC64 fast-isel
implementation. I corrected a couple of commentary lapses, and added
documentation of future opportunities. I also implemented
TargetMaterializeAlloca, which I somehow forgot when I split up the
original huge patch.
Finally, I decided to delete SelectCmp. I hadn't previously hooked it
in to TargetSelectInstruction(), and when I did I realized it wasn't
serving any useful purpose. This is only useful for compares that
don't feed a branch in the same block, and to handle that we would
have to have logic to interpret i1 as a condition register. This
could probably be done, but would require Unseemly Hackery, and
honestly does not seem worth the hassle.
This ends the current patch series.
