Alexey Bataev 9d9e406684 [OPENMP][NVPTX]Fix barriers and parallel level counters, NFC.
Summary:
Parallel level counter should be volatile to prevent some dangerous
optimiations by the ptxas. Otherwise, ptxas optimizations lead to
undefined behaviour in some cases.
Also, use __threadfence() for #pragma omp flush and if the barrier
should not be used (we have only one thread in the team), still perform
flush operation since the standard requires implicit flush when
executing barriers.

Gheorghe-Teodor Bercea 9e9c918259 [OpenMP][libomptarget] Enable requires flags for target libraries.
Summary:
Target link variables are currently implemented by creating a copy of the variables on the device side and unified memory never gets exploited.

When the prgram uses the:

```
#pragma omp requires unified_shared_memory
```

directive in conjunction with a declare target link, the linked variable is no longer allocated on the device and the host version is used instead.

This behavior is overridden by performing an explicit mapping.

A Clang side patch is required.

Paul Osmialowski 0732fcc7d5 Fix hwloc topology traversal code unable to handle situation where L2 cache is common for the packages
Currently cores within package that share the same L2 cache are grouped together.
The current logic behind this assumes that the L2 cache is always at deeper
(or the same) level than the package itself. In case when L2 cache is common
for all packages (and the packages are at deeper level than L2 cache) the whole of
the further topology discovery fails to find any computational units resulting in
following assertion:

Assertion failure at kmp_affinity.cpp(715): nActiveThreads == __kmp_avail_proc.
OMP: Error #13: Assertion failure at kmp_affinity.cpp(715).

This patch adds a bit of a logic that prevents such situation from occurring.

Eli Friedman 025df3b827 [OpenMP][AArch64] Fix compile with LLVM trunk.
The code is currently using the ambiguous instruction
"sub sp, sp, w9, lsl #4". The ARM reference manual says this isn't
valid, and it's not clear whether it's supposed to mean uxtw or uxtx.

It doesn't matter which instruction we use here, since the high
bits of the operand are zero anyway, so I arbitrarily choose uxtw, to
preserve the register name.

Jonathan Peyton c107332583 [OpenMP] Workaround gfortran bugzilla build bug 41755
This patch provides workaround to allow gfortran to compile the
OpenMP Fortran modules.

From the gfortran manual:
https://gcc.gnu.org/onlinedocs/gcc-9.1.0/gfortran/BOZ-literal-constants.html

"Note that initializing an INTEGER variable with a statement such as
DATA i/Z'FFFFFFFF'/ will give an integer overflow error rather than the desired
result of -1 when i is a 32-bit integer on a system that supports 64-bit
integers. The -fno-range-check option can be used as a workaround for legacy
code that initializes integers in this manner."

Dimitry Andric 181aff63fb Add non-SSE wrapper for __kmp_{load,store}_mxcsr
Summary:
To be able to successfully build OpenMP on FreeBSD/i386, which still
uses i486 as its default processor, I had to provide wrappers for the
`__kmp_load_mxcsr` and `__kmp_store_mxcsr` functions.

If the compiler signals that SSE is not available, loading and storing
mxcsr does not make sense anway, so in that case the inline functions
are empty.  This gives the minimum amount of code churn.

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.

On most platforms, certain compiler and linker flags have to be passed
when using pthreads, otherwise linking against libomp.so might fail with
undefined references to several pthread functions.

Use CMake's `find_package(Threads)` to determine these for standalone
builds, or take them (and optionally modify them) from the top-level
LLVM cmake files.

Also, On FreeBSD, ensure that libomp.so is linked against libm.so,
similar to NetBSD.

Adjust test cases with hardcoded `-lpthread` flag to use the common
build flags, which should now have the required pthread flags.

section.
