Reid Kleckner 6af8e1e64c Remove unneeded ymath.h include from int_math.h
This avoids a conflict between stdbool.h, which defines bool to _Bool in
xkeycheck.h. From what I can tell, ymath.h is an internal header, and
the intention is that users should include math.h directly instead. It
doesn't appear to provide declarations of anything required for our
builtins. This include was added back in r249513 from 2015, and it's
possible that ymath.h provided something this code needed at the time,
but today it does not.

Nico Weber 04347d848d Make SourceManager::createFileID(UnownedTag, ...) take a const llvm::MemoryBuffer*
Requires making the llvm::MemoryBuffer* stored by SourceManager const,
which in turn requires making the accessors for that return const
llvm::MemoryBuffer*s and updating all call sites.

The original motivation for this was to use it and fix the TODO in
CodeGenAction.cpp's ConvertBackendLocation() by using the UnownedTag
version of createFileID, and since llvm::SourceMgr* hands out a const
llvm::MemoryBuffer* this is required. I'm not sure if fixing the TODO
this way actually works, but this seems like a good change on its own
anyways.

No intended behavior change.

Jonathan Peyton b727d384a3 [OpenMP] Fix hang on Windows
Debug dump on large machine shows when many OpenMP threads (401 in total)
sleep on a barrier, one of the innermost nesting levels sleeps
on a child's b_arrived flag whose value is equal to 4 and is equal to
checker value. i.e., (1) sleep bit is 0, and (2) done_check() would
return true if called.

It is unclear how this might happen. It could be Windows Server 2016's
error of EnterCriticalSection / LeaveCriticalSection, or
error of WaitForSingleObject / SetEvent / ResetEvent, or
error in the library which is very difficult to find.

As a workaround, change INFINITE wait to timed wait, so that each
thread awakens each 5 seconds (the timeout was chosen arbitrary to not
disturb other threads much), check flag condition under the lock, and
either go to sleep again or stop sleeping as a result of the check.

Reid Kleckner 41fe3a54c2 Ensure that ManagedStatic is constant initialized in MSVC 2017 & 2019
Fixes PR41367.

This effectively relands r357655 with a workaround for MSVC 2017.

I tried various approaches with unions, but I ended up going with this
ifdef approach because it lets us write the proper C++11 code that we
want to write, with a separate workaround that we can delete when we
drop MSVC 2017 support.

This also adds LLVM_REQUIRE_CONSTANT_INITIALIZATION, which wraps
[[clang::require_constant_initialization]]. This actually detected a
minor issue when using clang-cl where clang wasn't able to use the
constexpr constructor in MSVC's STL, so I switched back to using the
default ctor of std::atomic<void*>.

Pavel Labath dfaafbcf4c Breakpad: Refine record classification code
Previously we would classify all STACK records into a single bucket.
This is not really helpful, because there are three distinct types of
records beginning with the token "STACK" (STACK CFI INIT, STACK CFI,
STACK WIN). To be consistent with how we're treating other records, we
should classify these as three different record types.

It also implements the logic to put "STACK CFI INIT" and "STACK CFI"
records into the same "section" of the breakpad file, as they are meant
to be read together (similar to how FUNC and LINE records are treated).

The code which performs actual parsing of these records will come in a
separate patch.

Jonas Paulsson c56ffed304 [SystemZ] Bugfix in isFusableLoadOpStorePattern()
This function is responsible for checking the legality of fusing an instance
of load -> op -> store into a single operation. In the SystemZ backend the
check was incomplete and a test case emerged with a cycle in the instruction
selection DAG as a result.

Instead of using the NodeIds to determine node relationships,
hasPredecessorHelper() now is used just like in the X86 backend. This handled
the failing tests and as well gave a few additional transformations on
benchmarks.

The SystemZ isFusableLoadOpStorePattern() is now a very near copy of the X86
function, and it seems this could be made a utility function in common code
instead.
