OpenMP: Add -Wopenmp and use it
The new warning has two purposes: First, it makes clearer to the
user that it is about OpenMP and, secondly and more importantly,
it permits to use -Wno-openmp.
The newly added -Wopenmp is enabled by default and replaces the
'0' (always warning) in several OpenMP-related warning calls.
For code shared with OpenACC, it only uses OPT_Wopenmp for
'flag_openmp | flag_openmp_simd'.
gcc/c-family/ChangeLog:
* c.opt (Wopenmp): Add, enable by default.
gcc/c/ChangeLog:
* c-parser.cc (c_parser_omp_clause_num_threads,
c_parser_omp_clause_num_tasks, c_parser_omp_clause_grainsize,
c_parser_omp_clause_priority, c_parser_omp_clause_schedule,
c_parser_omp_clause_num_teams, c_parser_omp_clause_thread_limit,
c_parser_omp_clause_dist_schedule, c_parser_omp_depobj,
c_parser_omp_scan_loop_body, c_parser_omp_assumption_clauses):
Add OPT_Wopenmp to warning_at.
gcc/cp/ChangeLog:
* parser.cc (cp_parser_omp_clause_dist_schedule,
cp_parser_omp_scan_loop_body, cp_parser_omp_assumption_clauses,
cp_parser_omp_depobj): Add OPT_Wopenmp to warning_at.
* semantics.cc (finish_omp_clauses): Likewise.
gcc/ChangeLog:
* doc/invoke.texi (-Wopenmp): Add.
* gimplify.cc (gimplify_omp_for): Add OPT_Wopenmp to warning_at.
* omp-expand.cc (expand_omp_ordered_sink): Likewise.
* omp-general.cc (omp_check_context_selector): Likewise.
* omp-low.cc (scan_omp_for, check_omp_nesting_restrictions,
lower_omp_ordered_clauses): Likewise.
* omp-simd-clone.cc (simd_clone_clauses_extract): Likewise.
gcc/fortran/ChangeLog:
* lang.opt (Wopenmp): Add, enabled by dafault and documented in C.
* openmp.cc (gfc_match_omp_declare_target, resolve_positive_int_expr,
resolve_nonnegative_int_expr, resolve_omp_clauses,
gfc_resolve_omp_do_blocks): Use OPT_Wopenmp with gfc_warning{,_now}.
