ChangeLog:
* mdebugread.c (mdebug_type_void, mdebug_type_char, mdebug_type_short, mdebug_type_int, mdebug_type_int_32, mdebug_type_int_64, mdebug_type_long_32, mdebug_type_long_64, mdebug_type_long_long_64, mdebug_type_unsigned_char, mdebug_type_unsigned_short, mdebug_type_unsigned_int_32, mdebug_type_unsigned_int_64, mdebug_type_unsigned_long_32, mdebug_type_unsigned_long_64, mdebug_type_unsigned_long_long_64, mdebug_type_adr_32, mdebug_type_adr_64, mdebug_type_float, mdebug_type_double, mdebug_type_complex, mdebug_type_double_complex, mdebug_type_fixed_dec, mdebug_type_float_dec, mdebug_type_string): Remove. (basic_type_data): New global variable. (basic_type): New function. (parse_type): Remove static basic type map map_bt. Call basic_type to get basic types instead of using mdebug_type_ variables. (parse_symbol): Use builtin types instead of mdebug_type_ variables. (upgrade_type): Likewise. (parse_procedure): Likewise. (psymtab_to_symtab_1): Likewise. (_initialize_mdebugread): Do not initialize mdebug_type_ variables. Initialize basic_type_data. include/coff/ChangeLog: * symconst.h (btLong64, btULong64, btLongLong64, btULongLong64, btAdr64, btInt64, btUInt64): New defines.
