amdgcn: libgomp plugin USM implementationdevel/omp/gcc-11
Implement the Unified Shared Memory API calls in the GCN plugin.
The allocate and free are pretty straight-forward because all "target" memory
allocations are compatible with USM, on the right hardware. However, there's
no known way to check what memory region was used, after the fact, so we use a
splay tree to record allocations so we can answer "is_usm_ptr" later.
libgomp/ChangeLog:
* plugin/plugin-gcn.c (struct usm_splay_tree_key_s): New.
(usm_splay_compare): New.
(splay_tree_prefix): New.
(GOMP_OFFLOAD_usm_alloc): New.
(GOMP_OFFLOAD_usm_free): New.
(GOMP_OFFLOAD_is_usm_ptr): New.
(GOMP_OFFLOAD_supported_features): Move into the OpenMP API fold.
Add GOMP_REQUIRES_UNIFIED_ADDRESS and
GOMP_REQUIRES_UNIFIED_SHARED_MEMORY.
(gomp_fatal): New.
(splay_tree_c): New.
* testsuite/lib/libgomp.exp (check_effective_target_omp_usm): New.
* testsuite/libgomp.c++/usm-1.C: Use dg-require-effective-target.
* testsuite/libgomp.c-c++-common/requires-1.c: Likewise.
* testsuite/libgomp.c/usm-1.c: Likewise.
* testsuite/libgomp.c/usm-2.c: Likewise.
* testsuite/libgomp.c/usm-3.c: Likewise.
* testsuite/libgomp.c/usm-4.c: Likewise.
* testsuite/libgomp.c/usm-5.c: Likewise.
* testsuite/libgomp.c/usm-6.c: Likewise.
