problems than it fixes.
* hppa-tdep.c (skip_prologue): If we exit the main loop without
finding all the register saves, retry again without looking for
the registers we could not find the first time.
Better fix for 7768.
calls "main" directly.
(skip_prologue): Always assume arguments were saved into the stack
since GCC will do so without setting the magic Args_Saved bit in
the unwind descriptor.
* (unwind_command): Clean it up and make it print things out
nicer.
* monitor.c: Add ^C handling capability (mostly ripped off from
remote.c).
* (monitor_printf): Make it check the command echo.
* (monitor_printf_noecho): Similar to above, but doesn't check
for echo.
* (monitor_stop): No longer waits for prompt. That is the job of
the caller. This makes things work much better for monitor_wait,
which waits for the prompt itself.
* (monitor_open): Deal with new monitor_stop semantics. Also,
flush input after sending init strings to get rid of junk that may
be output. Also, don't always send \r to remote. Use
monitor_ops->line_term cuz proper character isn't always \r.
* (monitor_fetch_register): Switch to completely different
algorithm to deal with lame-ass monitors which put spaces in the
middle of numbers, and prompt with a space!!!!!
* (monitor_read_memory_single): New routine to be used with
monitors that can only return one byte/short/long at a time. This
is selected via MO_GETMEM_READ_SINGLE.
* (monitor_load_srec): Use monitor_printf_noecho for sending S
records. Most targets don't echo them.
* (monitor.h): Get rid of cmd_delim. Add line_delim.
* op50n-rom.c (op50n_cmds): Fill it up. Make it work.
* w89k-rom.c: Change all eols from \r to \n. Change load_resp to
^Q to prevent error message.
* config/pa/tm-hppa.h (CALL_DUMMY (for hppro)): Add special
instruction sequence at end to make restore_pc_queue happy.
constants into PA instructions.
* Put #ifdefs around all signal handling code. Not generally
needed for embedded boards.
* (hppa_fix_call_dummy): Parameterize offsets into call dummy to
allow different dummys to be used by this code. Use
INSTRUCTION_SIZE instead of REGISTER_SIZE for things.
Conditionalize setup of _sr4export fixup. Improve comments.
* config/pa/tm-hppa.h: Define INSTRUCTION_SIZE. Use a different
call dummy if PA_LEVEL_0 is defined. Better comments for call
dummys. Define offsets for LDIL/LDO instructions which load
function addresses.
* config/pa/tm-pro.h: Get rid of signal handling stuff. Define
PA_LEVEL_0 to disable mucking with space regs and such.
extract_unsigned_integer and friends, not SWAP_TARGET_AND_HOST.
* defs.h, findvar.c: Move SWAP_TARGET_AND_HOST back to findvar.c.
Rename it to SWAP_FLOATING to make it clear it is no longer for
integers.
export stubs and actual shared library functions so that lazy
binding works correctly. Try both __d_plt_call and __gcc_plt_call
trampolines for calling import stubs.
space ID to place in the stack & inf_status structure.
(hppa_pop_frame): Don't walk through trampoline code if popping a
call dummy frame.
(hppa_fix_call_dummy): Call the stack dummy directly if the
current PC is in a shared library.
in_syscall bit in flags. Don't depend on the PC queue registers
when in_syscall is set, they're not valid.
* config/pa/tm-hppa.h (PUSH_DUMMY_FRAME): Pass inf_status down to
push_dummy_frame.
(SR4_REGNUM): Define.
* hppa-tdep.c: Misc. lint changes.
* somsolib.h (som_solib_get_got_by_pc): Add extern decl.
* hppa-tdep.c (hppa_fix_call_dummy): Handle case where FUN is the
function's export stub or real address in a shared library.
* hppa-tdep.c (hppa_pop_frame): Silently restart the inferior and
allow it to execute any return path trampoline code. Stop the
inferior and give the user control when the trampoline has
finished executing.
(in_solib_call_trampoline): Handle export stubs which also perform
parameter relocations.
(in_solib_return_trampoline): Likewise.
_sr4export and $$dyncall as trampolines. Likewise for long-call
stubs and parameter relocation stubs.
(in_solib_return_trampoline): Recognize a return trampoline for
return value relocation stubs.
Various name changes to match those used by hp-symtab.h.
No longer sanitize away hpread changes. Merge ChangeLog.hpread into
ChangeLog and ChangeLog-93.
symbol special handling when INHIBIT_SUNSOLIB_TRANSFER_TABLE_HACK
is defined.
* infrun.c (IN_SOLIB_CALL_TRAMPOLINE): Renamed from
IN_SOLIB_TRAMPOLINE. All callers changed.
(IN_SOLIB_RETURN_TRAMPOLINE): Provide default definition.
(wait_for_inferior): Handle single stepping through trampolines on
return paths from shared libraries.
* config/pa/tm-hppa.h (IN_SOLIB_CALL_TRAMPOLINE): Use
in_solib_call_trampoline.
(IN_SOLIB_RETURN_TRAMPOLINE): Use in_solib_return_trampoline.
(INHIBIT_SUNSOLIB_TRANSFER_TABLE_HACK): Define.
* hppa-tdep.c (in_solib_call_trampoline): New function.
(in_solib_return_trampoline): New function.
* somsolib.c (som_solib_add): Check the value of __dld_flags, if
it indicates __dld_list is not valid return an error. If it
indicates that libraries were not mapped privately, issue a
warning.
user code.
* hppa-tdep.c (internalize_unwinds): Accept and use new
"text_offset" argument for dynamic relocation of
region_{start,end} fields in the unwind descriptor.
(read_unwind_info): Pass text_offset to internalize unwinds.
retrieving the PC from a signal handler caller. Fix thinko
in Stan's last change ("frame", should have been "frame->next").
If the next frame is a signal handler caller and it's a system
call which has entered the kernel ((PSW & 0x2) != 0), then the
saved pc is in %r2 instead of %r31.
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.
* infrun.c (save_inferior_status, restore_inferior_status),

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.
(hpread.o): Add dependencies.
* somread.c: Do not include "aout/aout64.h". SOM has nothing to
do with a.out.
(BYTES_IN_WORD): Delete.
(som_symfile_read): Call hpread_build_psymtabs to build any
minimal symbols based on the HP C native debug symbols.
(som_symfile_finish): Call hpread_symfile_finish.
(som_symfile_init): Call hpread_symfile_init.
* config/pa/tm-hppa.h (HPREAD_ADJUST_STACK_ADDRESS): Define.
* hppa-tdep.c (hpread_adjust_stack_address): New function.
* config/pa/hppabsd.mh (NATDEPFILES): Add hpread.o
* config/pa/hppahpux.mh (NATDEPFILES): Likewise.
* hpread.c: New file.

(frame_saved_pc): Correctly restart the search for the saved
pc when a linker stub is encountered.
* hppa-tdep.c (inst_saves_gr): Handle 16 and 8 bit instruction
register stores emitted by the version 9 HP compilers.
(inst_saves_fr): Relax test for a specific base register (%r1);
this avoids losing with the version 9 HP compilers.
(skip_prologue): Try to skip argument stores emitted by the HP
compilers. It's not perfect, but it's better than before.
* 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.
