Tim Shen aec68b263d [InstCombine] Simplify and correct folding fcmps with the same children
Summary: Take advantage of FCmpInst::Predicate's bit pattern and handle (fcmp *, x, y) | (fcmp *, x, y) and (fcmp *, x, y) & (fcmp *, x, y) more consistently. Also fold more FCmpInst::FCMP_FALSE and FCmpInst::FCMP_TRUE to constants.

Currently InstCombine wrongly folds (fcmp ogt, x, y) | (fcmp ord, x, y) to (fcmp ogt, x, y); this patch also fixes that.

Etienne Bergeron f1d4e44d61 [compiler-rt] Fix passing debug information to unittest.
Summary:
On windows, the debug information was not present in the unittest executables,
which make them hard to debug.

The Sanitizer Unittests are compiled with a local clang build.
The link pass is also done by calling clang.

This pass is adding the appropriate flags to bring the right debug information
to these executables.

Jonathan Peyton fdcca8cd55 Fix omp_sections_nowait.c test to address Bugzilla Bug 28336
This rewrite of the omp_sections_nowait.c test file causes it to hang if the
nowait is not respected. If the nowait isn't respected, the lone thread which
can escape the first sections construct will just sleep at a barrier which
shouldn't exist. All reliance on timers is taken out. For good measure, the test
makes sure that all eight sections are executed as well. The test should take no
longer than a few seconds on any modern machine.

Rafael Espindola 2211f015cc Don't verify inputs to the Linker if ODR merging.
This fixes pr28072.

The point, as Duncan pointed out, is that the file is already
partially linked by just reading it.

Long term I think the solution is to make metadata owned by the module
and then the linker will lazily read it and be in charge of all the
linking. Running a verifier in each input will defeat the lazy
loading, but will be legal.

Right now we are at the unfortunate position that to support odr
merging we cannot verify the inputs, which mildly annoying (see test
update).

Reid Kleckner ad1e22bf33 Re-land "[MS] Don't expect vftables to be provided for extern template instantiations"
Reverts r273305 and re-instates r273296.

We needed to fix a bug in Sema::MarkVTableUsed to ensure that operator
delete lookup occurs when the vtable is referenced. We already had a
special case to look up operator delete when dllimport was used, but I
think should really mark virtual destructors referenced any time the
vtable is used.

Ahmed Bougacha 15a2f6d58c [X86] Lower blended PACKUSes using appropriate types.
When lowering two blended PACKUS, we used to disregard the types
of the PACKUS inputs, indiscriminately generating a v16i8 PACKUS.

This leads to non-selectable things like:
    (v16i8 (PACKUS (v4i32 v0), (v4i32 v1)))

Instead, check that the PACKUSes have the same type, and use that
as the final result type.

Benjamin Kramer 832d042078 [ManagedStatic] Reimplement double-checked locking with std::atomic.
This gets rid of the memory fence in the hot path (dereferencing the
ManagedStatic), trading for an extra mutex lock in the cold path (when
the ManagedStatic was uninitialized). Since this only happens on the
first accesses it shouldn't matter much. On strict architectures like
x86 this removes any atomic instructions from the hot path.

Also remove the tsan annotations, tsan knows how standard atomics work
so they should be unnecessary now.

Pavel Labath f17635375a Remove platform plugins from lldb-server
Summary:
This removes the last usage of Platform plugins in lldb-server -- it was used for launching child
processes, where it can be trivially replaced by Host::LaunchProces (as lldb-server is always
running on the host).

Removing platform plugins enables us to remove a lot of other unused code, which was pulled in as
a transitive dependency, and it reduces lldb-server size by 4%--9% (depending on build type and
architecture).

George Rimar e86dcd0cbd [ELF] - Added support for --unresolved-symbols option.
Option has next description (http://linux.die.net/man/1/ld):
"--unresolved-symbols=method
Determine how to handle unresolved symbols. There are four possible values for method
according to documentation:

ignore-all: Do not report any unresolved symbols.
report-all: Report all unresolved symbols. This is the default.
ignore-in-object-files: Report unresolved symbols that are contained in shared libraries, but ignore them if they come from regular object files.
ignore-in-shared-libs: Report unresolved symbols that come from regular object files, but ignore them if they come from shared libraries."

Since report-all is default and we traditionally do not report about undefined symbols in lld,
report-all does not report about undefines from DSO. 
ignore-in-object-files also does not do that. Handling of that option differs from what gnu linkers do.

Option works in next way in lld:
ignore-all: Do not report any unresolved symbols.
report-all: Report all unresolved symbols except symbols from DSOs. This is the default.
ignore-in-object-files: The same as ignore-all.
gnore-in-shared-libs: The same as report-all.

This is PR24524.

Sagar Thakur 067b6edc1f [LLDB][MIPS] Check if libatomic needs to be specified explicitly
Patch by Nitesh Jain.

Summary : The problem appears while linking liblldb.so. The class Address contain atomic variable m_offset. The loading and storing of variable is access via atomic_load_8 and atomic_store_8 functions. Some target fail to implicitly link libatomic, which cause undefine reference to atomic_store_8/atomic_load_8. This patch uses http://reviews.llvm.org/D20896 to check if libatomic need to be explicitly link.
