+Fri Oct 7 08:48:18 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
+
+ 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.
+
Fri Oct 7 12:17:17 1994 Ian Lance Taylor <ian@sanguine.cygnus.com>
* top.c (target_byte_order_auto): New static variable.
