"INFO PROCESSES" command; (close_procinfo_file): call new
function "delete_thread" to cleanup GDB's thread database;
(proc_init_failed): add new argument "kill", to control whether

exit from an attached process, and cleanup procinfo handles
when the process exits; (procfs_resume, procfs_wait): cleanup
after a thread when it exits; (do_attach, do_detach): handle
attached processes with multiple threads; plus some general
improvements in the diagnostic output.

implementation; (thread_to_lwp, lwp_to_thread): enhance to
handle threads that may have exited; (sol_thread_attach): add
startup setup stuff; (sol_thread_detach): add unpush_target
call; (sol_thread_mourn_inferior): add unpush_target call;
(sol_thread_wait, sol_thread_resume): enhance to deal with
thread exit cleanly; (sol_thread_new_objfile,
sol_thread_pid_to_str): detect unsuccessful startup and
don't crash; plus some general cleanup.
* thread.c (delete_thread): new function, allows targets to
notify gdb when a thread is no longer valid.
* infrun.c (wait_for_inferior): don't try to detect a new
thread on receiving a TARGET_EXITED event.
* rs6000-tdep.c (frameless_function_invocation): Mark frames
with a zero PC as frameless to improve backtraces from core dumps
caused by dereferencing a NULL function pointer.
(frameless_function_invocation, frame_saved_pc, rs6000_frame_chain):
Handle frameless functions interrupted by a signal.
* sparc-tdep.c (sparc_init_extra_frame_info, sparc_frame_saved_pc):
Handle frameless functions interrupted by a signal.
* Finalize merge from Hurd folk.

* thread.c (thread_apply_command, thread_apply_all_command,
thread_command): Make sure TP is alive.
(thread_alive): New function.
Tue Nov 14 14:31:03 1995 Miles Bader <miles@gnu.ai.mit.edu>
* infrun.c (sig_print_info): Deal better with long signal names.
Wed Nov 22 15:23:35 1995 Miles Bader <miles@gnu.ai.mit.edu>
* thread.c (thread_id_to_pid): New function.
Fri Dec 1 13:25:25 1995 Miles Bader <miles@gnu.ai.mit.edu>
* gnu-nat.c: (set_thread_cmd_list, show_thread_cmd_list,
set_thread_default_cmd_list, show_thread_default_cmd_list):
New variables. (set_thread_cmd, show_thread_cmd,
set_thread_default_cmd, show_thread_default_cmd): New functions.
Fri Apr 18 15:20:16 1997 Miles Bader <miles@gnu.ai.mit.edu>
* gnu-nat.c (inf_startup): remove TASK parameter.
(inf_set_task): replace with new function (inf_set_pid).
* gdbthread.h: Add extern decl for thread_cmd_list.
* Makefile.in: Add rule for gnu-nat.o and i386gnu-nat.o (Gnu Hurd)
* config/i386/i386gnu.mh: remove rules for [i386]gnu-nat.o, now
in Makefile.in (as for other targets); add NATDEPFILE corelow.o to
satisfy symbol dependancy in solib.c (core_ops).
* target.[ch] conditionalize Mach-specific signals so that they
won't show up in non-Mach gdb's!
* thread.c: add function thread_id_to_pid; change name of static
function "thread_switch" to "switch_to_thread", to avoid conflict
with Mach global symbol; move thread_cmd_list to global scope
so targets can add their own thread commands.
* infrun.c: sig_print_info: allow for long signal names.
* gnu-nat.[ch]: tidying up comments.
* gnu-nat.c: move several functions to static scope, just for tidy;
remove calls to prune_threads and renumber_threads;
gnu_wait must not return -1 when inferior exits;
attach_to_child will modify inferior_pid in a way that allows
fork_inferior to remain unchanged;
remove extra arg from startup_inferior;
move mach-specific thread commands here from thread.c.
* procfs.c: Minor changes to make pre-ANSI compilers happy.
(procfs_notice_signals): Copy traced signal set back to
pi->prrun.pr_trace.
(unconditionally_kill_inferior): If PR_DEAD is defined,
rerun inferior after killing it.
floatformat_ieee_double_littlebyte_bigword for little endian
target byte order.
* utils.c (floatformat_to_doublest): Create local preswapped
copy of input for floatformat_littlebyte_bigword formats.
(get_field, put_field): Treat floatformat_littlebyte_bigword
the same as floatformat_little.
(floatformat_from_doublest): Postswap output words for
the floatformat_littlebyte_bigwords format.
does not require a command line arg, since most simulators
don't currently support passing such an arg into the simulated
program.
* gdb.base/commands.exp: Change tests to insert the proper
value as the arg to the first recursive factorial call. Change
compilation line to define FAKEARGV at compile time.
