* [OpenMP] Fixes for LIBOMP_OMP_VERSION=45/40Roman Lebedev2018-12-151-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [OpenMP] Initial implementation of OMP 5.0 Memory Management routinesJonathan Peyton2018-09-071-0/+78
Implemented omp_alloc, omp_free, omp_{set,get}_default_allocator entries, and OMP_ALLOCATOR environment variable. Added support for HBW memory on Linux if libmemkind.so library is accessible (dynamic library only, no support for static libraries). Only used stable API (hbwmalloc) of the memkind library though we may consider using experimental API in future. The ICV def-allocator-var is implemented per implicit task similar to place-partition-var. In the absence of a requested allocator, the uses the default allocator. Predefined allocators (the only ones currently available) are made similar for C and Fortran, - pointers (long integers) with values 1 to 8.
