re PR c/10962 (lookup_field is a linear search on a linked list (can be slow if large struct))
2003-07-16 Andrew Pinski <pinskia@physics.uc.edu>
ChangeLog:
PR c/10962
* ggc.h: Add header guards.
* c-decl.c (finish_struct): Sort fields if
number greater than 15 and there are no
anonymous structs/unions.
* c-common.h: Include ggc.h.
(sorted_fields_type): New struct.
(field_decl_cmp): New prototype.
(resort_sorted_fields): New prototype.
(DECL_DECLARES_TYPE_NON_TEMPLATE_P): New macro.
* c-tree.h: (lang_type): Use pointer to sorted_fields_type
as s, removing other fields.
* c-typeck.c (lookup_field): Use s in lang_type.
These were mostly moved from cp/class.c:
* c-common.c (field_decl_cmp): New static function.
(field_decl_cmp): New function.
(resort_sorted_fields): New function.
cp/ChangeLog:
* class.c (field_decl_cmp): Remove.
(resort_field_decl_cmp): Remove.
(resort_sorted_fields): Remove.
(add_fields_to_vec): Rename to ...
(add_fields_to_record_type): this.
(finish_struct_1): Change to be using
sorted_fields_type's fields.
* cp-tree.h (lang_decl): In lang_decl_u3
change sorted_fields to be a pointer to
sorted_fields_type.
(resort_sorted_fields): Remove prototype.
* search.c (lookup_field_1): Change to be using
sorted_fields_type's fields.
