* m68k/tm-delta68.h (EXTRACT_RETURN_VALUE): Type argument for
`REGISTER_CONVERT_TO_VIRTUAL is `TYPE', not
`REGISTER_VIRTUAL_TYPE (FP0_REGNUM)';
(STORE_RETURN_VALUE): Ditto, and offset for `write_register_bytes'
is `REGISTER_BYTE (FP0_REGNUM)', not `FP0_REGNUM'.
(FRAME_NUM_ARGS): New macro.
* m68k/tm-news.h (EXTRACT_RETURN_VALUE, STORE_RETURN_VALUE): Ditto.
* delta68-nat.c (clear_insn_cache): New function, forgotten in previous
patch.
