+ * rs6000-tdep.c: Use the modern gdbarch methods for handling the
+ register set, so our regcache isn't declared "legacy" and our E500
+ pseudoregister read and write functions aren't ignored.

+ rs6000_register_convert_to_raw): Deleted.
+ (rs6000_register_type, rs6000_convert_register_p,

+ gdbarch_deprecated_register_convertible,
