5d394f7072 * Makefile.in: Add rule for hpux-thread.o (needs special header
files).
	* (SUBDIRS):  Remove mswin.
	* Change procedure for creating init.c.  Speeds things up quite a
	bit.
	* config.in configure configure.in:  Check for select, poll.
	* Check for OSF header files before including hpux-thread.o.
	* Don't configure doc or testsuite when building under MSVC.
	* findvar.c value.h (read_register_pid write_register_pid):  Make
	global.  Needed for hppa-tdep.c.
	* (supply_register):  Don't set pid to inferior_pid when supplying
	registers.

	FRAME_SAVED_PC.
	* (frame_saved_pc):  Change name to hppa_frame_saved_pc.
	* (hppa_pop_frame):  Don't use a pid of 0 with target_write_pc.
	Use write_pc instead, which uses the correct pid.
	* (target_read_pc target_write_pc):  Use read/write_register_pid
	instead of read/write_register to preserve the pid passed in.
	* inftarg.c (child_can_run):  Add flag child_suppress_run to allow
	hpux-threads.c to override this as a runnable target.
	* config/pa/nm-hppah.h:  Define target_new_objfile and
	target_pid_to_str.
	* config/pa/tm-hppa.h (FRAME_SAVED_PC):  Use hppa_frame_saved_pc
	instead of frame_saved_pc.
	* config/m68k/tm-m68k.h:  Define TARGET_M68K for Wingdb.
	* config/m68k/tm-monitor.h:  Use FRAME_CHAIN_VALID_ALTERNATE, since
	we can't easily determine the start file bounds with ELF.
	* config/mips/tm-mips.h:  Define TARGET_MIPS for Wingdb.
	* hpux-thread.c:  New file for HPUX/OSF thread support.
	* osf-share/{README AT386/cma_thread_io.h HP800/cma_thread_io.h

problems than it fixes.
	* hppa-tdep.c (skip_prologue): If we exit the main loop without

Jeff Law
c85ff3a363 * hppa-tdep.c (frame_chain_valid): Handle systems where "$START$"
calls "main" directly.
	(skip_prologue): Always assume arguments were saved into the stack

d8afcce964 * hppa-tdep.c (read_unwind_info): Cosmetic cleanup.
* (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.
1995-05-11 02:26:00 +00:00
Stu Grossman
7486c68d68 * hppa-tdep.c (deposit_17): New routine to deposit 17 bit
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.

Jim Kingdon
bc28e68dad * hppa-tdep.c (pa_print_registers), monitor.c: Use

	* 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.
1995-03-01 07:18:04 +00:00
Kung Hsu
326ae3e292 * defs.h: define SWAP_TARGET_AND_HOST macro.
* findvar.c, monitor.c, hppa-tdep.c: remove definition of
        SWAP_TARGET_AND_HOST.
1995-02-28 23:08:06 +00:00
Per Bothner
5222ca60be * valops.c (value_arg_coerce): Now takes param_type argument.
(call_function_by_hand):  Convert arguments with value_arg_coerce
	early, and overwrite original args with converted args.
	No longer need multiple calls to value_arg_coerce.
	(value_arg_push):  Removed.
	* hppa-tdep.c (hppa_push_arguments):  No longer call value_arg_coerce.
	* mips-tdep.c (mips_push_arguments):  Likewise.
	* alpha-tdep.c (alpha_push_arguments):  Likewise.
	* rs6000-tdep.c (push_arguments, ran_out_of_registers_for_arguments):
	Likewise.

Jim Kingdon
16726dd15b 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.
