possible nested-if confusion.

prototypes.

a prototype for this function.
(mfree): Add prototypes for mmalloc, mrealloc, mfree if we aren't
using mmalloc.
* ax-gdb.c breakpoint.c coffread.c corelow.c dbxread.c dwarf2read.c
dwarfread.c elfread.c eval.c exec.c gdbtk-cmds.c gdbtk.c infcmd.c
infrun.c mipsread.c nlmread.c os9kread.c parse.c printcmd.c symfile.c
symmisc.c symtab.c thread.c top.c tracepoint.c typeprint.c valops.c:
Cast parameters passed to make_cleanup to use the new
make_cleanup_func typedef.
More warning cleanups. There are still a bunch of places where the first
argument to make_cleanup is not cast to (make_cleanup_func); these are
either due to the function fitting the make_cleanup_func specification
already (e.g. free()) or they are in files that weren't compiled when
I did my make on a Linux native system. Bwahahaha. You can see them
like this:
grep make_cleanup\ * | grep -v make_cleanup_func
I'll surely go back and clean up the remaining suspicious calls in
GDB one of these days. :-)

and stack pointer during stepping, to speed things up.
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
()) instead of stop_frame_address.

stop_frame_address.
* 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.
* inferior.h, infcmd.c: New variable step_sp.
* infcmd.c (step_1, until_next_command): Set it.
* infrun.c: Remove prev_sp and replace uses by step_sp.

range, then set step_sp to the current stack pointer before we
start going again.

called via the *_breakpoint_hook functions.

other files to make sure that calls to error and warning will
work. Call init_ui_hook after everything else.
* utils.c (query): Call query_hook if set.
* (gdb_flush): Call flush_hook if set.
* Change _initialize_utils to initialize_utils cuz we don't use
automatic initialization of utils.c anymore.

watchpoints. Delete the watchpoint and watchpoint scope breakpoint
when the watchpoint goes out of scope. Remove and reinsert all

I386_REGNO_TO_SYMMETRY check in case it is needed for Dynix
someday.

stuff from PTRACE_READ_REGS, PTRACE_WRITE_REGS macros to

which performs one (the check_sigtramp2 one) of the functions
which had been handled by the step_resume_breakpoint. For each
use of the step_resume_breakpoint, make it still use the
step_resume_breakpoint, use the through_sigtramp_breakpoint, or
operate on both.
Deal with BPSTAT_WHAT_THROUGH_SIGTRAMP return from bpstat_what.
