+ Change to match functions above.
+
+
+ * NEWS: Add item about if and while.
+
+ * .gdbinit: Restore `end'; it was not excess. Reindent
+ list-objfiles to make this clear. Comment out all of
+ list-objfiles because old gdb's choke on it.
+
+
+ * config/mips/tm-bigmips64.h: Just define TARGET_BYTE_ORDER and
+ include tm-mips64.h.
+
+
+ * Makefile.in (ANNOTATE_OBS): New definition.

+ Lynx wait status.
+ (fetch_core_registers): Don't try to fetch a register if
+ regmap maps it to -1.
+ * sparc-tdep.c (sparc_frame_find_saved_regs): Use FRAME_SAVED_I0
+ and FRAME_SAVED_L0 when setting saved_regs_addr. SPARC Lynx
+ stores the registers in a weird order.
+
+
+ * blockframe.c (reinit_frame_cache): Reinstate select_frame call
+ if inferior_pid is nonzero.
+
+
+ Speed up GDB startup time by not demangling partial symbols.

+
+ * breakpoint.h (bpstat_stop_status): Fix prototype declaration.
+
+
+ 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),

+ 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

+ 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.
+
+
+ * top.c (target_byte_order_auto): New static variable.
+ (set_endian): Mention that ``auto'' is permitted.

+ defined:
+ (endianlist, target_byte_order): New variables.
+ (set_endian, set_endian_big, set_endian_little): New functions.
+ (show_endian): New function.
+ (init_cmd_lists): Initialize endianlist.
+ (init_main): Add commands ``set endian big'', ``set endian
+ little'', and ``show endian''.
+ * a29k-pinsn.c: Rewrite uses of TARGET_BYTE_ORDER and
+ BITS_BIG_ENDIAN to switch at run time rather than at compile time.
+ * coffread.c, dwarfread.c, findvar.c, mips-tdep.c: Likewise.
+ * remote-os9k.c, stabsread.c, valarith.c, valprint.c: Likewise.
+ * values.c: Likewise.

+
+ * nlm/Makefile.in: Get rid of NWINCLUDES.
+ * config/{alpha,powerpc}/gdbserve.mt: Remove NWINCLUDES.
+ User should now configure with --with-headers.
+
+
+ * gdbserver/server.c (main): Silently accept all unrecognized
+ requests and send back a zero length acknowledge. That is what

+ * lynx-nat.c (child_wait): Pass fourth argument to ptrace.
+

+ Remove item about specifying arbitrary locations of stack frames
+ (this works on some machines).
+ Remove item about debugging functions without a frame pointer
+ (this works on some machines).

+ since that item was written.
+ Remove item about gdb catching SIGINT when attached; this is done.
+ Remove item about having list_command not read symbols--why bother?
+
+
+ * TODO: Append contents of Projects file.
+ * Projects: Remove.
+
+
+ * corelow.c (add_solib_stub): Remove copying of to_sections,
+ pass current_target to SOLIB_ADD. The Sep 10 change failed

+ copy the modified to_sections vector from current_target to
+ core_ops, so that core_close can free it later.

+
+
+ * dbxread.c (read_dbx_dynamic_symtab): Cast bfd_asymbol_name to

+
+
+ * gdbtk.tcl: Let ^U delete lines in the command window.
+
+
+ * cp-valprint.c (static_field_print): New variable, controls
+ printing of static members.

+
+ * solib.c: Remove inclusion of libelf.h and elf/mips.h.
+ (elf_locate_base): Use only standard BFD functions to collect

+ elegantly. Also, create special window to display file open
+ failure message. Move opening of file prior to creation of text
+ widget.
+ * (create_asm_win): Add PC as argument. We now base disassembly
+ on PC instead of function name, since function names can be
+ ambiguous (usually seen with shared libs). Also, use catch to
+ simplify code where we don't care about failures.
+ * source.c (symtab_to_filename): New. Returns the file
+ associated with a symtab.
+ * top.c: Define interactive_hook. Called during QUIT to animate
+ the GUI.
