New Revision: 236830

URL: https://gcc.gnu.org/viewcvs?rev=236830&root=gcc&view=rev
Log:
	* gfortran.h (enum gfc_statement): Add ST_OMP_ORDERED_DEPEND.
	(enum gfc_omp_depend_op): Add OMP_DEPEND_SINK_FIRST and
	OMP_DEPEND_SINK.
	(struct gfc_omp_clauses): Add depend_source field.
	* parse.c (decode_omp_directive): If ordered directive has
	depend clause as the first of the clauses, use
	gfc_match_omp_ordered_depend and ST_OMP_ORDERED_DEPEND instead of
	gfc_match_omp_ordered and ST_OMP_ORDERED.
	(case_executable): Add ST_OMP_ORDERED_DEPEND case.
	(gfc_ascii_statement): Handle ST_OMP_ORDERED_DEPEND.
	* st.c (gfc_free_statement): Free omp clauses even for
	EXEC_OMP_ORDERED.
	* dump-parse-tree.c (show_omp_namelist): Handle OMP_DEPEND_SINK_FIRST
	depend_op.
	(show_omp_clauses): Handle depend_source.
	(show_omp_node): Print clauses for EXEC_OMP_ORDERED.  Allow NULL
	c->block for EXEC_OMP_ORDERED.
	* trans-openmp.c (gfc_trans_omp_clauses): Handle OMP_DEPEND_SINK_FIRST
	depend_op.  Handle orderedc and depend_source.
	(gfc_trans_omp_do): Set collapse to orderedc if non-zero.  Fill in
	OMP_FOR_ORIG_DECLS for doacross loops.
	(gfc_trans_omp_ordered): Translate omp clauses, allow NULL
	code->block.
	(gfc_split_omp_clauses): Copy orderedc together with ordered.
	* frontend-passes.c (gfc_code_walker): Handle EXEC_OMP_ORDERED.
	* openmp.c (gfc_match_omp_depend_sink): New function.
	(gfc_match_omp_clauses): Parse depend(source) and depend(sink: ...).
	(OMP_ORDERED_CLAUSES): Define.
	(gfc_match_omp_ordered): Parse clauses.
	(gfc_match_omp_ordered_depend): New function.
	(resolve_omp_clauses): Require orderedc >= collapse if specified.
	Handle depend(sink:) and depend(source) restrictions.  Disallow linear
	clause when orderedc is non-zero.
	(gfc_resolve_omp_do_blocks): Set omp_current_do_collapse to orderedc
	if non-zero.
	(resolve_omp_do): Set collapse to orderedc if non-zero.
	* match.h (gfc_match_omp_ordered_depend): New prototype.
	* match.c (match_exit_cycle): Rename collapse variable to count,
	set it to orderedc if non-zero, instead of collapse.
