Todd Fiala 57a4e5b3d0 Fix TestEvents.py on OS X
This change addresses a hang/segfault in TestEvents.py. The threads that
run the listener loops now do an SBListener.Clear() before they wrap up
their work. This prevents the test from trying to clean up the
SBListener too late.

There is a separate issue here which is that we should prevent this
clean-up time lock-up, but that is out of scope for this particular
change. I'd like to get these tests back and running the normal flow
rather than skipping them.

This addresses:
llvm.org/pr25924 (at least, the OS X side, although I suspect this will
also address Linux)

Kevin Enderby b34e3a1877 Clean up the specific error message for a malformed Mach-O files with bad segment
load commands.

The existing test case in test/Object/macho-invalid.test for
macho-invalid-too-small-segment-load-command has a cmdsize of 55, while
being too small also it is not a multiple of 4.  So when that check is added
this test case will produce a different error. So I constructed a new test case
that will trigger the intended error.

I also changed the error message to be consistent with the other malformed Mach-O
file error messages which prints the load command index.  I also removed both
object_error::macho_load_segment_too_small and
object_error::macho_load_segment_too_many_sections from Object/Error.h
as they are not needed and can just use object_error::parse_failed and let the
error message string distinguish the specific error.

Nicolai Haehnle ffbd56a1c9 AMDGPU: Uniform branch conditions can originate with intrinsics
Summary:
Discovered by Dave Airlie, fixes an assertion in Khronos OpenGL CTS
GL43-CTS.shader_storage_buffer_object.advanced-matrix.

In this particular case, the buffer load intrinsic fed into a uniform
conditional branch, and led the brcond lowering down the wrong path.

Peter Collingbourne 3ad1c1e242 ELF: Undefine all symbols, not just those that we expect to be defined.
This allows the combined LTO object to provide a definition with the same
name as a symbol that was internalized without causing a duplicate symbol
error. This normally happens during parallel codegen which externalizes
originally-internal symbols, for example.

In order to make this work, I needed to relax the undefined symbol error to
only report an error for symbols that are used in regular objects.

Mehdi Amini 03abce901c llvm-lto: add a -thinlto-module-id that enables to force the Module identifier.
ThinLTO is using the Module Identifier to find the corresponding entry
in the index. However when reproducing part of the flow from temporary
files generated from the linker, you'd like to process a file and
force llvm-lto to use another module identifier than the current
filename. The alternative would be to tweak the index, which would be
more involved.

Jonathan Peyton 11dc82fa83 [STATS] Use partitioned timer scheme
This change removes the current timers with ones that partition time properly.
The current timers are nested, so that if a new timer, B, starts when the
current timer, A, is already timing, A's time will include B's. To eliminate
this problem, the partitioned timers are designed to stop the current timer (A),
let the new timer run (B), and when the new timer is finished, restart the
previously running timer (A). With this partitioning of time, a threads' timers
all sum up to the OMP_worker_thread_life time and can now easily show the
percentage of time a thread is spending in different parts of the runtime or
user code.

There is also a new state variable associated with each thread which tells where
it is executing a task. This corresponds with the timers: OMP_task_*, e.g., if
time is spent in OMP_task_taskwait, then that thread executed tasks inside a
#pragma omp taskwait construct.

The changes are mostly changing the MACROs to use the new PARITIONED_* macros,
the new partitionedTimers class and its methods, and new state logic.

Krzysztof Parzyszek e57662d5ec [Hexagon] Handle operand type differences for A2_tfrpi
The instruction A2_tfrpi has a 64-bit operand, while the corresponding
intrinsic takes a 32-bit value. The actual value has only 8 significant
bits, so the difference is only in the type used to represent it.
In order to map the intrinsic to the instruction, the operand needs to
be extended to the correct type.

Silviu Baranga c05bab8a9c [LV] Identify more induction PHIs by coercing expressions to AddRecExprs
Summary:
Some PHIs can have expressions that are not AddRecExprs due to the presence
of sext/zext instructions. In order to prevent the Loop Vectorizer from
bailing out when encountering these PHIs, we now coerce the SCEV
expressions to AddRecExprs using SCEV predicates (when possible).

We only do this when the alternative would be to not vectorize.

James Y Knight 0c145c0c3a Remove bit-rotten CppBackend.
This backend was supposed to generate C++ code which will re-construct
the LLVM IR passed as input. This seems to me to have very marginal
usefulness in the first place.

However, the code has never been updated to use IRBuilder, which makes
its current value negative -- people who look at the output may be
steered to use the *wrong* C++ APIs to construct IR.

Furthermore, it's generated code that doesn't compile since at least
2013.

Teresa Johnson 9254ebe3c0 [ThinLTO] Emit individual index files for distributed backends
Summary:
When launching ThinLTO backends in a distributed build (currently
supported in gold via the thinlto-index-only plugin option), emit
an individual index file for each backend process as described here:
http://lists.llvm.org/pipermail/llvm-dev/2016-April/098272.html

The individual index file encodes the summary and module information
required for implementing the importing/exporting decisions made
for a given module in the thin link step.
This is in place of the current mechanism that uses the combined index
to make importing decisions in each back end independently. It is an
enabler for doing global summary based optimizations in the thin link
step (which will be recorded in the individual index files), and reduces
the size of the index that must be sent to each backend process, and
the amount of work to scan it in the backends.

Rather than create entirely new ModuleSummaryIndex structures (and all
the included unique_ptrs) for each backend index file, a map is created
to record all of the GUID and summary pointers needed for a particular
index file. The IndexBitcodeWriter walks this map instead of the full
index (hiding the details of managing the appropriate summary iteration
in a new iterator subclass). This is more efficient than walking the
entire combined index and filtering out just the needed summaries during
each backend bitcode index write.

Depends on D19481.

David Majnemer 911d0e3c21 [X86] Use the right type when folding xor (truncate (shift)) -> setcc
The result type of setcc is dependent on whether or not AVX512 is
present.
We had an X86-specific DAG-combine which assumed that the result type
should be i8 when it could be i1.
This meant that we would generate illegal setccs which LowerSETCC did
not like.

Instead, use an appropriate type and zero extend to i8.

Also, there were some scenarios where the fold should have fired but
didn't because we were overly cautious about the types.  This meant that
we generated:

        shrl    $31, %edi
        andl    $1, %edi
        kmovw   %edi, %k0
        kxnorw  %k0, %k0, %k1
        kshiftrw        $15, %k1, %k1
        kxorw   %k1, %k0, %k0
        kmovw   %k0, %eax

instead of:
