* 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.
