before de-referencing it. Prevents deref of NULL pointer if core
file lacks .reg section.
* defs.h: Rename floatformat_{to from}_long_double to
floatformat_{to from}_doublest. Get rid of FLOATFORMAT_{TO
FROM}... macros.
* findvar.c (extract_floating store_floating): Change all refs to
FLOATFORMAT_{FROM TO}... to floatformat_{from to}_doublest.
* utils.c: Change floatformat_{to from}_long_double to
floatformat_{to from}_doublest cuz the new routines will use
whatever size (double or long double) is appropriate.
* config/i960/tm-i960.h (REGISTER_CONVERT_TO_VIRTUAL
REGISTER_CONVERT_TO_RAW): Change FLOATFORMAT... macros to
floatformat... routine calls.
shared library breakpoints that have been temporarily disabled.
* breakpoint.c: Handle temporarily disabled shared library
breakpoints like disabled breakpoints in most places.
(insert_breakpoints): Use shlib_disabled to indicate
that an unsettable breakpoint is only temporarily disabled.
(re_enable_breakpoints_in_shlibs): New function.
* corelow.c (solib_add_stub): After adding shared libraries,
try to reenable any temporarily disabled breakpoints.
* infcmd.c (attach_command): Likewise.
* infrun.c (wait_for_inferior): Likewise.
Hopefully the last 7763 related patches for a while.
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.
* sparc-tdep.c (sparc_pop_frame), infcmd.c (run-stack_dummy),
infrun.c (wait_for_inferior), thread.c (thread_switch),
convex-tdep.c (set_thread_command), a29k-tdep.c (pop_frame),

config/ns32k/tm-umax.h (POP_FRAME), config/tahoe/tm-tahoe.h
(POP_FRAME), config/vax/tm-vax.h (POP_FRAME): Don't
call create_new_frame.
* corelow.c (core_open), altos-xdep.c (core_file_command),
arm-xdep.c (core_file_command), gould-xdep.c (core_file_command),
m3-nat.c (select_thread), sun386-nat.c (core_file_command),
umax-xdep.c (core_file_command): Don't call create_new_frame; do
call flush_cached_frames.
* 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.
* infrun.c (save_inferior_status, restore_inferior_status),
inferior.h (struct inferior_status): Don't save and restore
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.
* infrun.c (wait_for_inferior): If we get out of the step
range, then set step_sp to the current stack pointer before we
start going again.
pass current_target to SOLIB_ADD. The Sep 10 change failed
if SOLIB_ADD errored out, or if SOLIB_ADD was trying to access
target memory.
* corelow.c (core_open): After reading the shared libraries,
copy the modified to_sections vector from current_target to
core_ops, so that core_close can free it later.
* config/rs6000/nm-rs6000.h, rs6000-nat.c (xcoff_relocate_core):
Pass down target parameter from SOLIB_ADD and use it instead of
directly accessing core_ops.
core_ops to current_target after adding the shared libraries.
* partial-stab.h (N_EXCL), dbxread.c (add_old_header_file,
find_corresponding_bincl_psymtab): Change `repeated header not seen'
error to a complaint, simplify complaint.
* procfs.c (signalname, errnoname): Make `name' const.
* symfile.c (reread_symbols): Use filename from old BFD to
reopen the objfile.
* values.c (record_latest_value): Don't record value in the
history chain until we are sure there won't be an error.
* Add rule for annotate.o to keep Sun make happy.
* configure.in: Add config for powerpc/Netware.
* partial-stab.h (near N_SO): Don't call START_PSYMTAB with null
filename. This speeds up handling of trailing N_SO stabs (they
mark the end of a .o file).
* target.c, target.h: Change the way pushing and popping of
targets work to support target overlays and inheritance.
* corelow.c, hppa-tdep.c, inflow.c, remote-nindy.c, utils.c:
Fixup references to current_target, due to previous changes.
* config/i386/tm-i386nw.h: Enable longjmp support. More work is
needed to get the address of longjmp out of the target.
gone now.

m2-exp.y, minsyms.c, nlmread.c, parse.c, putenv.c, regex.c
remote-utils.c, stabsread.c: Include <string.h>.
* regex.c: Include "defs.h", change re_comp argument to const char *.
* infptrace.c (fetch_register, store_inferior_registers): Change
regaddr to type CORE_ADDR.
* config/alpha/alpha-nw.mt, config/alpha/alpha-osf1.mt (MT_CFLAGS):
Remove, no longer necessary now that we use bfd_vma for a CORE_ADDR.
Change all references to stdout/stderr to gdb_stdout/gdb_stderr.
Replace all calls to stdio output functions with calls to
corresponding _unfiltered functions (`fprintf_unfiltered')
Replaced calls to fopen for output to gdb_fopen.
Added sufficient goo to utils.c and defs.h to make the above work.
The net effect is that stdio output functions are only directly used
in utils.c. Elsewhere, the _unfiltered and _filtered functions and
GDB_FILE type are used.
In the near future, GDB_FILE will stop being equivalant to FILE.
The semantics of some commands has changed in a very subtle way:
called in the right context, they may cause new occurences of
prompt_for_continue() behavior. The testsuite doesn't notice anything
like this, though.
Please respect this change by not reintroducing stdio output
dependencies in the main body of gdb code. All output from commands
should go to a GDB_FILE.
Target-specific code can still use stdio directly to communicate with
targets.
that clears the `inserted' flag for all breakpoints and deletes
any breakpoints which should go away between runs of programs.
* inflow.c (generic_mourn_inferior), infrun.c (init_wait_for_inferior),
remote-es.c (es1800_load), comments in exec.c and corelow.c:
Use it instead of mark_breakpoints_out.
* breakpoint.c (mark_breakpoints_out): Update comment, tm-rs6000.h
uses it in a completely different context.
* breakpoint.c (breakpoint_re_set_one): Add bp_call_dummy case.
* core.c: Add commands to set and show it.
* Callers to bfd_*open*: Pass gnutarget instead of NULL as target.
* environ.c (set_in_environ): For GNUTARGET, use set_gnutarget not
putenv.
* symtab.c (decode_line_1): Give error on unmatched single quote.
