From: Bernhard Reutner-Fischer <al...@gcc.gnu.org>
This gets rid of some of the str[n]*cmp in favour of (faster) pointer
equality checks.
gcc/fortran/ChangeLog:
2017-11-02 Bernhard Reutner-Fischer <al...@gcc.gnu.org>
* check.c (gfc_check_move_alloc): Use pointer comparison instead
of strcmp.
* class.c (find_intrinsic_vtab): Likewise.
* decl.c (find_special, check_function_name, variable_decl,
insert_parameter_exprs, gfc_get_pdt_instance,
gfc_match_formal_arglist, match_result, add_hidden_procptr_result,
add_global_entry, gfc_match_end): Likewise.
* interface.c (gfc_match_end_interface, compare_components,
gfc_compare_derived_types, find_keyword_arg, count_types_test,
generic_correspondence, compare_actual_formal,
gfc_check_typebound_override): Likewise.
* match.c (gfc_match_else, gfc_match_elseif, match_case_eos,
gfc_match_elsewhere): Likewise.
* openmp.c (gfc_match_oacc_routine, match_udr_expr,
gfc_omp_udr_find): Likewise.
* parse.c (match_deferred_characteristics,
parse_omp_structured_block, add_global_procedure): Likewise.
* resolve.c (check_proc_interface, resolve_formal_arglist,
resolve_contained_fntype, resolve_common_blocks,
count_specific_procs, not_entry_self_reference,
resolve_global_procedure, resolve_select_type,
gfc_verify_binding_labels, build_init_assign, compare_fsyms,
resolve_typebound_procedure, resolve_component): Likewise.
* symbol.c (gfc_add_component, gfc_find_component): Likewise.
* trans-array.c (structure_alloc_comps): Likewise.
* trans-decl.c (gfc_get_extern_function_decl, build_entry_thunks,
gfc_get_fake_result_decl, struct module_hasher,
module_decl_hasher::equal, gfc_trans_use_stmts,
generate_local_decl): Likewise.
* trans-expr.c (conv_parent_component_references,
gfc_conv_procedure_call): Likewise.
* module.c (mio_namelist, find_symbol, load_omp_udrs,
read_module): Likewise.
