OpenMP: Add C++ support for 'omp allocate' with stack variables
gcc/c/ChangeLog:
* c-parser.cc (c_parser_omp_allocate): Change error
wording.
gcc/cp/ChangeLog:
* cp-tree.h (finish_omp_allocate): New prototype.
* parser.cc (struct cp_omp_loc_tree,
cp_check_omp_allocate_allocator_r): New.
(cp_parser_omp_allocate): Call it; remove sorry,
improve checks, call finish_omp_allocate.
* pt.cc (tsubst_stmt): Call finish_omp_allocate.
* semantics.cc (finish_omp_allocate): New.
libgomp/ChangeLog:
* libgomp.texi (OpenMP Impl. Status): Document that 'omp allocate'
is now supported for C++ stack/automatic variables.
* testsuite/libgomp.c-c++-common/allocate-4.c: Renamed from ...
* testsuite/libgomp.c/allocate-4.c: ... this.
* testsuite/libgomp.c-c++-common/allocate-5.c: Renamed from ...
* testsuite/libgomp.c/allocate-5.c: ... this.
* testsuite/libgomp.c-c++-common/allocate-6.c: Renamed from ...
* testsuite/libgomp.c/allocate-6.c: ... this.
* testsuite/libgomp.c++/allocate-2.C: New test.
gcc/testsuite/ChangeLog:
* c-c++-common/gomp/allocate-5.c: Remove C++ 'sorry'; minor updates.
* c-c++-common/gomp/allocate-9.c: Likewise.
* c-c++-common/gomp/allocate-17.c: Likewise.
* c-c++-common/gomp/directive-1.c: Likewise.
* g++.dg/gomp/allocate-5.C: New test.
