PR fortran/92568

gcc/fortran/ChangeLog:

	* dump-parse-tree.c (show_omp_clauses): Update for defaultmap.
	* f95-lang.c (LANG_HOOKS_OMP_ALLOCATABLE_P,
	LANG_HOOKS_OMP_SCALAR_TARGET_P): New.
	* gfortran.h (enum gfc_omp_defaultmap,
	enum gfc_omp_defaultmap_category): New.
	* openmp.c (gfc_match_omp_clauses): Update defaultmap matching.
	* trans-decl.c (gfc_finish_decl_attrs): Set GFC_DECL_SCALAR_TARGET.
	* trans-openmp.c (gfc_omp_allocatable_p, gfc_omp_scalar_target_p): New.
	(gfc_omp_scalar_p): Take 'ptr_alloc_ok' argument.
	(gfc_trans_omp_clauses, gfc_split_omp_clauses): Update for
	defaultmap changes.
	* trans.h (gfc_omp_scalar_p): Update prototype.
	(gfc_omp_allocatable_p, gfc_omp_scalar_target_p): New.
	(struct lang_decl): Add scalar_target.
	(GFC_DECL_SCALAR_TARGET, GFC_DECL_GET_SCALAR_TARGET): New.

gcc/ChangeLog:

	* gimplify.c (enum gimplify_defaultmap_kind): Add GDMK_SCALAR_TARGET.
	(struct gimplify_omp_ctx): Extend defaultmap array by one.
	(new_omp_context): Init defaultmap[GDMK_SCALAR_TARGET].
	(omp_notice_variable): Update type classification for Fortran.
	(gimplify_scan_omp_clauses): Update calls for new argument; handle
	GDMK_SCALAR_TARGET; for Fortran, GDMK_POINTER avoid GOVD_MAP_0LEN_ARRAY.
	* langhooks-def.h (lhd_omp_scalar_p): Add 'ptr_ok' argument.
	* langhooks.c (lhd_omp_scalar_p): Likewise.
	(LANG_HOOKS_OMP_ALLOCATABLE_P, LANG_HOOKS_OMP_SCALAR_TARGET_P): New.
	(LANG_HOOKS_DECLS): Add them.
	* langhooks.h (struct lang_hooks_for_decls): Add new hooks, update
	omp_scalar_p pointer type to include the new bool argument.
