Michal Gorny a70184ba92 [runtime] [test] Fix using %python path
Fix the newly-added tests to use %python substitution in order to use
the correct path to Python interpreter.  Otherwise, they fail on NetBSD
where there is no 'python', just 'pythonX.Y'.

Joachim Protze 0e0d6cdd58 [OMPT] First chunk of final OMPT 5.0 interface updates
This patch updates the implementation of the ompt_frame_t, ompt_wait_id_t
and ompt_state_t. The final version of the OpenMP 5.0 spec added the "t"
for these types.
Furthermore the structure for ompt_frame_t changed and allows to specify
that the reenter frame belongs to the runtime.

Roman Lebedev 781a0896b0 [OpenMP] Fixes for LIBOMP_OMP_VERSION=45/40
Summary:
I have discovered this because i wanted to experiment with
building static libomp (with openmp-4.0 support only)
for debugging purposes.

There are three kinds of problems here:
1. `__kmp_compare_and_store_acq()` simply does not exist.
   It was added in D47903 by @jlpeyton.
   I'm guessing `__kmp_atomic_compare_store_acq()` was meant.
2. In `__kmp_is_ticket_lock_initialized()`,
   `lck->lk.initialized` is `std::atomic<bool>`,
   while `lck` is `kmp_ticket_lock_t *`.
   Naturally, they can't be equality-compared.
   Either, it should return the value read from `lck->lk.initialized`,
   or do what `__kmp_is_queuing_lock_initialized()` does,
   compare the passed pointer with the field in the struct
   pointed by the pointer. I think the latter is correct-er choice here.
3. Tests were not versioned.
   They assume that `LIBOMP_OMP_VERSION` is at the latest version.

This does not touch LIBOMP_OMP_VERSION=30. That is still broken.

Jonathan Peyton bdb0a2ffaa [OpenMP] Fix transient divide by zero bug in 32-bit code
The value returned by __kmp_now_nsec() can overflow 32-bit values causing
incorrect values to be returned. The overflow can end up causing a divide
by zero error because in __kmp_initialize_system_tick(), the value
(__kmp_now_nsec() - nsec) can end up being much larger than the numerator:
1e6 * (delay + (now - goal))
during a pathological timing where the current time calculated is much larger
than nsec. When this happens, the value of __kmp_ticks_per_msec is set to zero
which is then used as the denominator in the KMP_NOW_MSEC() macro leading to
the divide by zero error.

Jonathan Peyton 6d88e049dc [OpenMP] Implement OpenMP 5.0 affinity format functionality
This patch adds the affinity format functionality introduced in OpenMP 5.0.
This patch adds: Two new environment variables:

OMP_DISPLAY_AFFINITY=TRUE|FALSE
OMP_AFFINITY_FORMAT=<string>
and Four new API:
1) omp_set_affinity_format()
2) omp_get_affinity_format()
3) omp_display_affinity()
4) omp_capture_affinity()
The affinity format functionality has two ICV's associated with it:
affinity-display-var (bool) and affinity-format-var (string).
The affinity-display-var enables/disables the functionality through the
envirable OMP_DISPLAY_AFFINITY. The affinity-format-var is a formatted
string with the special field types beginning with a '%' character
similar to printf
For example, the affinity-format-var could be:
"OMP: host:%H pid:%P OStid:%i num_threads:%N thread_num:%n affinity:{%A}"

The affinity-format-var is displayed by every thread implicitly at the beginning
of a parallel region when any thread's affinity has changed (including a brand
new thread being spawned), or explicitly using the omp_display_affinity() API.
The omp_capture_affinity() function can capture the affinity-format-var in a
char buffer. And omp_set|get_affinity_format() allow the user to set|get the
affinity-format-var explicitly at runtime. omp_capture_affinity() and
omp_get_affinity_format() both return the number of characters needed to hold
the entire string it tried to make (not including NULL character). If not
enough buffer space is available,
both these functions truncate their output.

There is similar patch for OpenBSD: https://reviews.llvm.org/D34280

The -lm was being omitted due to -Wl,--as-needed in cmake rule, similar patch is in freebsd-ports/devel/llvm-devel port.

$ LD_LIBRARY_PATH=/usr/local/llvm-devel/lib OMP_NUM_THREADS=100 ./a.out
