A. Changes to not select a frame until we need a selected frame:
* blockframe.c (flush_cached_frames): Call select_frame (NULL, -1).
* infrun.c (wait_for_inferior): Move call to select_frame back to
normal_stop. This reverts a change of 13 Apr 94 (it says Jeff
Law, but the change was my idea); the only reason for that change
was so we could save and restore the selected frame in
wait_for_inferior, and now that flush_cached frames clears the
selected frame, that should work OK now.
B. Changes to not create a current_frame until we need one:
* blockframe.c (get_current_frame): If current_frame is NULL, try
to create an innermost frame.

* blockframe.c (reinit_frame_cache): Don't call create_new_frame
or select_frame.
C. Changes to get rid of stop_frame_address and instead only
fetch the frame pointer when we need it.
* breakpoint.c (bpstat_stop_status): Remove argument
frame_address; use FRAME_FP (get_current_frame ()).
* infrun.c (wait_for_inferior): Don't pass frame pointer to
bpstat_stop_status.
* infrun.c (wait_for_inferior): Use FRAME_FP (get_current_frame

* inferior.h, infcmd.c, thread.c (thread_switch), m3-nat.c
(select_thread): Remove stop_frame_address and uses thereof.
D. Same thing for the stack pointer.
* infrun.c (wait_for_inferior): Remove stop_sp and replace
uses thereof with read_sp ().
E. Change to eliminate one nasty little spot where we were
wanting to know the frame pointer from before the current step
(idea from GDB 3.5, which saved my ass, because my other ideas of
how to fix it were very baroque).
* infrun.c: Remove prev_frame_address.
* infrun.c (wait_for_inferior, step_over_function): Use
step_frame_address instead of prev_frame_address.
F. Same basic idea for the stack pointer.

* infrun.c: Remove prev_sp and replace uses by step_sp.

start going again.

remote_debugging. Don't use repeat count unless it's > 0.

Handle extra arg.
* config/i386/xm-go32.h (GDBINIT_FILENAME): Set to gdb.ini.
(more work here to come)
* config/sh/tm-sh.h (EXTRA_FRAME_INFO): Add f_offset and leaf_function
fields.
