The point of these changes is to avoid reading the frame pointer
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.

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.

The point of these changes is to avoid reading the frame pointer
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),
alpha-tdep.c (alpha_pop_frame), convex-xdep.c (core_file_command),
h8300-tdep.c (h8300_pop_frame), h8500-tdep.c (h8300_pop_frame),
hppa-tdep.c (hppa_pop_frame), i386-tdep.c (i386_pop_frame),
i960-tdep.c (pop_frame), m68k-tdep.c
(m68k_pop_frame), mips-tdep.c (mips_pop_frame), rs6000-tdep.c
(push_dummy_frame, pop_dummy_frame, pop_frame), sh-tdep.c

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.

The point of these changes is to avoid reading the frame pointer
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),
alpha-tdep.c (alpha_pop_frame), convex-xdep.c (core_file_command),
h8300-tdep.c (h8300_pop_frame), h8500-tdep.c (h8300_pop_frame),
hppa-tdep.c (hppa_pop_frame), i386-tdep.c (i386_pop_frame),
i960-tdep.c (pop_frame), m68k-tdep.c
(m68k_pop_frame), mips-tdep.c (mips_pop_frame), rs6000-tdep.c
(push_dummy_frame, pop_dummy_frame, pop_frame), sh-tdep.c
(pop_frame), config/arm/tm-arm.h (POP_FRAME),
config/convex/tm-convex.h (POP_FRAME), config/gould/tm-pn.h
(POP_FRAME), config/ns32k/tm-merlin.h (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.

* symmisc.c (print_symbol): Use %02x not %2x for LOC_CONST_BYTES.
Clean up problems with targets and hosts that have 64 bit longs
and pointers and 32 bit ints.
* breakpoint.c, buildsym.c, c-lang.c, c-valprint.c, ch-lang.c,
ch-valprint.c, core.c, cp-valprint.c, dbxread.c, exec.c,
expprint.c, gdbtypes.c, infcmd.c, language.c, language.h,
m2-lang.c, maint.c, mips-tdep.c, mipsread.c, partial-stab.h,
printcmd.c, remote-vx.c, solib.c, source.c, stack.c, symfile.c,
symmisc.c, symtab.c, valops.c, valprint.c, xcoffexec.c:
Change all printf formats from %x to %lx if outputting an address.
Change la_*_format to use long format.
local_hex_string, local_hex_string_custom now take an unsigned long
argument, change all callers.
* coffread.c (read_coff_symtab): Remove superfluous cast for
complaint output.
* dbxread.c (end_psymtab): Cast MSYMBOL_INFO to long, not int.
* findvar.c, value.h (write_register): Change register value to long.
* gdbtypes.h (struct type): Change `bitsize' to long as
TYPE_FIELD_STATIC_PHYSNAME uses this field as a pointer.
* inferior.h (struct inferior_status): Change type of stop_pc to
CORE_ADDR.
* language.h (local_octal_string, local_octal_string_custom):
Remove prototype, the functions are neither defined nor used.
* mipsread.c (parse_symbol): Use temporary variable for bitsize as
f->bitsize is a long now.
* objfiles.c (add_to_objfile_sections, build_objfile_section_table):
Use unsigned long casts instead of int for abusing sections_end
pointer as integer.
* stack.c (parse_frame_specification): Change type of `args' to
CORE_ADDR for SETUP_ARBITRARY_FRAME.
* printcmd.c (make_vasize): Allow redefinition via MAKEVA_SIZE.
* mipsread.c (parse_type): Alpha cc now supports the t->continued
bit, update algorithm to match the way the compiler uses it.

The point of these changes is to avoid reading the frame pointer
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.

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

D. Same thing for the stack pointer.

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

The point of these changes is to avoid reading the frame pointer
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.

C. Changes to get rid of stop_frame_address and instead only
fetch the frame pointer when we need it.

frame_address; use FRAME_FP (get_current_frame ()).
* infrun.c (wait_for_inferior): Don't pass frame pointer to
