* coffread.c (decode_type): Use builtin_type_int32 instead
of FT_INTEGER fundamental type for array range index type. (decode_base_type): Use builtin types of current_gdbarch instead of fundamental types. * dwarf2read.c (struct dwarf2_cu): Remove ftypes member. (read_file_scope): Do not initialize ftypes member. (dwarf_base_type, dwarf2_fundamental_types): Remove functions. (read_array_type): Use builtin_type_int32 instead of FT_INTEGER fundamental type for array range index type. (read_tag_string_type): Likewise for string range index type. Also, do not overwrite FT_CHAR type with new string type. (read_base_type): If DW_AT_name is missing, create unnamed type with given properties instead of looking for a fundamental type. Create new types as TYPE_TARGET_TYPE for DW_ATE_address and DW_ATE_complex_float types. (read_subrange_type): Create new type to represent missing DW_AT_type instead of looking for a fundamental type. (die_type): Use builtin type to represent "void" instead of looking for a fundamental type. * stabsread.c (define_symbol): Use builtin types to represent 'r' and 'i' floating-point and integer constants. * gdbtypes.c (lookup_fundamental_type): Remove. * gdbtypes.h (lookup_fundamental_type): Remove prototype.
