+        * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.

+
+        * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
+        HAVE_TIMER_SETTIME is defined.
+
+2012-09-30  Paul Eggert  <eggert@cs.ucla.edu>
+
+        Profiler improvements: more-accurate timers, overflow checks.
+        * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
+        signal.h, setjmp.h.  Include systime.h instead.
+        (saturated_add): New function.
+        (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
+        (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
+        (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
+        New static vars.
+        (enum profiler_cpu_running): New enum.
+        (profiler_cpu_running): Now of that enum type, not bool.
+        All uses changed to store the new value.
+        (handle_profiler_signal): Rename from sigprof_handler_1,
+        for consistency with other handlers.  Do not check whether
+        cpu_log is a hash-table if garbage collecting, since it
+        doesn't matter in that case.
+        (deliver_profiler_signal): Rename from sigprof_handler,
+        for consistency with other handlers.
+        (setup_cpu_timer): New function, with much of what used to be in
+        Fprofiler_cpu_start.  Check for out-of-range argument.
+        Prefer timer_settime if available, and prefer
+        thread cputime clocks, then process cputime clocks, then
+        monotonic clocks, to the old realtime clock.  Use make_timeval
+        to round more-correctly when falling back to setitimer.
+        (Fprofiler_cpu_start): Use it.
+        (Fprofiler_cpu_stop): Prefer timer_settime if available.
+        Don't assume that passing NULL as the 2nd argument of setitimer
+        is the same as passing a pointer to all-zero storage.
+        Ignore SIGPROF afterwards.
+        (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
+        * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
+        non-fatal signal handlers.  Ignore SIGPROF on startup.
+        * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
+        in profiler.c, since sysdep.c now uses it.
+
+        * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

+
+2012-09-27  Paul Eggert  <eggert@cs.ucla.edu>
+
+        Check more robustly for timer_settime.
+        * Makefile.in (LIB_TIMER_TIME): New macro.
+        (LIBES): Add it.
+        * atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
+        Use HAVE_TIMER_SETTIME, not SIGEV_SIGNAL, to decide whether to
+        call timer_settime.

+        * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
+
+2012-09-26  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * character.h (MAYBE_UNIFY_CHAR): Remove.
+        * charset.c, charset.h (maybe_unify_char): Now static.
+        * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
+        Since this stuff is now private to charset.c, there's no need for
+        a public macro and no need to inline by hand.

+        code.
+        (sys_kill): Improve commentary.
+
+        * w32.c (term_ntproc): Accept (and ignore) one argument, for
+        consistency with a signature of a signal handler.  All callers
+        changed.
+        (init_ntproc): Accept an argument DUMPING.  If dumping, don't
+        install term_ntproc as a signal handler for SIGABRT, as that
+        should be done by the dumped Emacs.
+

+
+        * w32select.c (term_w32select): Protect against repeated

+
+        Simplify and avoid signal-handling races (Bug#12471).
+        * alloc.c (die):
+        * sysdep.c (emacs_abort) [HAVE_NTGUI]:
+        Avoid recursive loop if there's a fatal error in the function itself.
+        * atimer.c (pending_atimers):
+        * blockinput.h: Don't include "atimer.h"; no longer needed.
+        (interrupt_input_pending): Remove.  All uses removed.
+        pending_signals now counts both atimers and ordinary interrupts.
+        This is less racy than having three separate pending-signal flags.
+        (block_input, unblock_input, totally_unblock_input, unblock_input_to)
+        (input_blocked_p):
+        Rename from their upper-case counterparts BLOCK_INPUT,
+        UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
+        INPUT_BLOCKED_P, and turn into functions.  All uses changed.
+        This makes it easier to access volatile variables more accurately.
+        (BLOCK_INPUT_RESIGNAL): Remove.  All uses replaced by unblock_input ().
+        (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
+        that's more reliable if the code is buggy and sets
+        interrupt_input_blocked to a negative value.  All uses changed.
+        * atimer.c (deliver_alarm_signal):
+        Remove.  No need to deliver this to the parent; any thread can
+        handle this signal now.  All uses replaced by underlying handler.

+        * dispnew.c (handle_window_change_signal):
+        * emacs.c (handle_danger_signal):
+        * keyboard.c (kbd_buffer_get_event):
+        Don't reestablish signal handler; not needed with sigaction.
+        * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
+        (UNBLOCK_INPUT_TO):
+        Rework to avoid unnecessary accesses to volatile variables.
+        (UNBLOCK_INPUT_TO): Now a function.
+        (totally_unblock_input, unblock_input): New decls.
+        * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
+        (init_data): Remove.  Necessary stuff now done in init_signal.
+        * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
+        * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
+        (fatal_error_code): Remove; no longer needed.
+        (terminate_due_to_signal): Rename from fatal_error_backtrace, since
+        it doesn't always backtrace.  All uses changed.  No need to reset
+        signal to default, since sigaction and/or die does that for us now.
+        Use emacs_raise (FOO), not kill (getpid (), FOO).
+        (main): Check more-accurately whether we're dumping.
+        Move fatal-error setup to sysdep.c
+        * floatfns.c: Do not include "syssignal.h"; no longer needed.
+        * gtkutil.c (xg_get_file_name, xg_get_font):
+        Remove no-longer-needed signal-mask manipulation.
+        * keyboard.c, process.c (POLL_FOR_INPUT):
+        Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
+        * keyboard.c (read_avail_input): Remove.
+        All uses replaced by gobble_input.
+        (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
+        (kbd_buffer_store_event_hold, gobble_input):
+        (record_asynch_buffer_change) [USABLE_SIGIO]:
+        (store_user_signal_events):
+        No need to mess with signal mask.
+        (gobble_input): If blocking input and there are terminals, simply
+        set pending_signals to 1 and return.  All hooks changed to not
+        worry about whether input is blocked.
+        (process_pending_signals): Clear pending_signals before processing
+        them, in case a signal comes in while we're processing.
+        By convention callers now test pending_signals before calling us.
+        (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
+        New functions, to support changes to blockinput.h.
+        (handle_input_available_signal): Now extern.
+        (reinvoke_input_signal): Remove.  All uses replaced by
+        handle_async_input.
+        (quit_count): Now volatile, since a signal handler uses it.
+        (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
+        All callers changed.  Block SIGINT only if not already blocked.
+        Clear sigmask reliably, even if Fsignal returns, which it can.
+        Omit unnecessary accesses to volatile var.
+        (quit_throw_to_read_char): No need to restore sigmask.
+        * keyboard.c (gobble_input, handle_user_signal):
+        * process.c (wait_reading_process_output):
+        Call signal-handling code rather than killing ourselves.
+        * lisp.h: Include <float.h>, for...
+        (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
+        (pending_signals): Now volatile.
+        (syms_of_data): Now const if IEEE floating point.
+        (handle_input_available_signal) [USABLE_SIGIO]:
+        (terminate_due_to_signal, record_child_status_change): New decls.
+        * process.c (create_process): Avoid disaster if memory is exhausted
+        while we're processing a vfork, by tightening the critical section
+        around the vfork.
+        (send_process_frame, process_sent_to, handle_pipe_signal)
+        (deliver_pipe_signal): Remove.  No longer needed, as Emacs now
+        ignores SIGPIPE.
+        (send_process): No need for setjmp/longjmp any more, since the
+        SIGPIPE stuff is now gone.  Instead, report an error if errno
+        is EPIPE.
+        (record_child_status_change): Now extern.  PID and W are now args.
+        Return void, not bool.  All callers changed.
+        * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
+        Remove.  All uses removed.  This bug should be fixed now in a
+        different way.
+        (wait_for_termination_1): Use waitpid rather than sigsuspend,
+        and record the child status change directly.  This avoids the
+        need to futz with the signal mask.
+        (process_fatal_action): Move here from emacs.c.
+        (emacs_sigaction_flags): New function, containing
+        much of what used to be in emacs_sigaction_init.
+        (emacs_sigaction_init): Use it.  Block nonfatal system signals that are
+        caught by emacs, to make races less likely.
+        (deliver_process_signal): Rename from handle_on_main_thread.
+        All uses changed.
+        (BACKTRACE_LIMIT_MAX): Now at top level.
+        (thread_backtrace_buffer, threadback_backtrace_pointers):
+        New static vars.
+        (deliver_thread_signal, deliver_fatal_thread_signal):
+        New functions, for more-accurate delivery of thread-specific signals.
+        (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
+        (deliver_arith_signal): Handle in this thread, not
+        in the main thread, since it's triggered by this thread.
+        (maybe_fatal_sig): New function.
+        (init_signals): New arg DUMPING so that we can be more accurate
+        about whether we're dumping.  Caller changed.
+        Treat thread-specific signals differently from process-general signals.
+        Block all signals while handling fatal error; that's safer.
+        xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
+        on IEEE hosts.
+        When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
+        Ignore SIGPIPE unless batch.
+        (emacs_backtrace): Output backtrace for the appropriate thread,
+        which is not necessarily the main thread.
+        * syssignal.h: Include <stdbool.h>.
+        (emacs_raise): New macro.
+        * xterm.c (x_connection_signal): Remove; no longer needed
+        now that we use sigaction.
+        (x_connection_closed): No need to mess with sigmask now.
+        (x_initialize): No need to reset SIGPIPE handler here, since
+        init_signals does this for us now.
