* remote-d10v.c (remote_d10v_open): Call push_remote_target
instead of open_remote_target.
* remote.c (remote_xfer_memory): Use REMOTE_TRANSLATE_XFER_ADDRESS
to translate addr/size when defined.
(open_remote_target): Delete.
* target.h (open_remote_target): Delete.
* config/d10v/tm-d10v.h (REMOTE_TRANSLATE_XFER_ADDRESS): Define.
Mon Feb 16 14:05:54 1998 Andrew Cagney <cagney@b1.cygnus.com>
* config/d10v/tm-d10v.h (USE_STRUCT_CONVENTION): Define. True when
sizeof type > 1.
