Wed Apr 17 17:09:48 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
* i386-tdep.c (i386_get_frame_setup): Use SWAP_TARGET_AND_HOST
before returning locals or slocals.
* i386-tdep.c (i386_follow_jump): Do not add data16 to pos in
call to codestream_seek; add one to pos if (and only if)
we are dealing with a jump with data16 == 1 (i.e. 0x66, 0xe9).
Mon Apr 15 12:04:32 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
* valops.c (call_function_by_hand): Put dummy1 in target order
before FIX_CALL_DUMMY.
* tm-i386v.h (FIX_CALL_DUMMY): Don't depend on host byte order.
Sun Apr 14 11:55:19 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
* valops.c (push_word): Add SWAP_TARGET_AND_HOST.
* remote.c (remote_open): Send '+' before calling putpkt().
* tm-i386v.h (REGISTER_VIRTUAL_TYPE): Return pointer to void,
not int, for pc, fp, and sp.
* remote.c (remote_open): Call start_remote after putpkt("?");
