+
+ * gdbtypes.h (struct main_type): Move artificial flag out of
+ loc. New member of ``struct field'' named static_kind. Reduce
+ overloaded meaning of bitsize.
+ (FIELD_ARTIFICIAL, SET_FIELD_PHYSNAME, SET_FIELD_PHYSADDR)
+ (TYPE_FIELD_STATIC, TYPE_FIELD_STATIC_HAS_ADDR): Likewise.
+ (FIELD_STATIC_KIND, TYPE_FIELD_STATIC_KIND): New macros.
+
+ * ada-lang.c (fill_in_ada_prototype): Initialize static_kind for
+ new fields.
+ (template_to_fixed_record_type, template_to_static_fixed_type)
+ (to_record_with_fixed_variant_part): Likewise.
+ * coffread.c (coff_read_struct_type, coff_read_enum_type): Likewise.
+ * dwarf2read.c (dwarf2_add_field, read_enumeration): Likewise.
+ * dwarfread.c (struct_type, enum_type): Likewise.
+ * hpread.c (hpread_read_enum_type)
+ (hpread_read_function_type, hpread_read_doc_function_type)
+ (hpread_read_struct_type): Likewise.
+ * mdebugread.c (parse_symbol): Likewise.

2002-11-10 Andrew Cagney <ac131313@redhat.com>
* breakpoint.h (deprecated_frame_in_dummy): Rename frame_in_dummy.
