	Discard killed buffers from deleted window and frame objects.
	This reduces an amount of references to killed buffers and
	helps GC to reclaim them faster.
	* alloc.c (discard_killed_buffers): New function.
	(mark_object): Use it for deleted windows and frames.
	(mark_object): If symbol's value is set up for a killed buffer
	or deleted frame, restore it's global binding.
	* data.c (swap_in_global_binding): Add GC notice.
	(swap_in_symval_forwarding): Use convenient set_blv_where.
	* window.c (wset_next_buffers, wset_prev_buffers): Move ...
	* window.h: ... to here.

	Convenient macro to check whether the buffer is live.
	* buffer.h (BUFFER_LIVE_P): New macro.
	* alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
	* minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.

	composition cases (Bug#12364).

	* xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
	overhang of succeeding glyphs overlapping box cursor.

	* w32term.c (x_draw_glyph_string): Likewise.

	Simplify, document, and port floating-point (Bug#12381).
	The porting part of this patch fixes bugs on non-IEEE platforms
	with frexp, ldexp, logb.
	* data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
	Now static.
	* floatfns.c: Simplify discussion of functions that Emacs doesn't
	support, by removing commented-out code and briefly listing the
	C89 functions excluded.  The commented-out stuff was confusing
	maintenance, e.g., we thought we needed cbrt but it was commented out.
	(logb): Remove decl; no longer needed.
	(isfinite): New macro, if not already supplied.
	(isnan): Don't replace any existing macro.
	(Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
	are present on all C89 platforms.
	(Ffrexp): Do not special-case zero, as frexp does the right thing
	for that case.
	(Flogb): Do not use logb, as it doesn't have the desired meaning
	on hosts that use non-base-2 floating point.  Instead, stick with
	frexp, which is C89 anyway.  Do not pass an infinity or a NaN to
	frexp, to avoid getting an unspecified result.

	* xdisp.c (Qinhibit_debug_on_message): Now static.

	* fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
	left fringe if the window has a left margin.  This avoids leaving
	traces of the cursor because its leftmost pixel is not drawn over.

83 84 85 86
	* dispnew.c (update_window_line): When the left margin area of a
	screen line is updated, set the redraw_fringe_bitmaps_p flag of
	that screen line.  (Bug#12277)

	Assume C89 or later for math functions (Bug#12381).
	This simplifies the code, and makes it a bit smaller and faster,
	and (most important) makes it easier to clean up signal handling
	since we can stop worring about floating-point exceptions in
	library code.  That was a problem before C89, but the problem
	went away many years ago on all practical Emacs targets.
	* data.c, image.c, lread.c, print.c:
	Don't include <math.h>; no longer needed.
	* data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
	might be autoconfigured, as that never happens.
	* data.c (fmod):
	* doprnt.c (DBL_MAX_10_EXP):
	* print.c (DBL_DIG):
	Remove.  C89 or later always defines these.
	* floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
	(in_float, float_error_arg, float_error_arg2, float_error_fn_name)
	(arith_error, domain_error, domain_error2):
	Remove all this pre-C89 cruft.  Do not include <errno.h> as that's
	no longer needed -- we simply return what C returns.  All uses removed.
	(IN_FLOAT, IN_FLOAT2): Remove.  All uses replaced with
	the wrapped code.
	(FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
	Remove.  All uses expanded, as these macros are no longer used
	more than once and are now more trouble than they're worth.
	(Ftan): Use tan, not sin / cos.
	(Flogb): Assume C89 frexp.
	(fmod_float): Assume C89 fmod.
	(matherr) [HAVE_MATHERR]: Remove; no longer needed.
	(init_floatfns): Remove.  All uses removed.

	* floatfns.c: Comment fix.
	* lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
	SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
	and anyway the declaration is harmless even if SIGDANGER is not defined.
	* syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
	defined BROKEN_FIONREAD).  systty.h formerly did this, but other
	source files not surprisingly expected syssignal.h to define, or
	not define, SIGIO, and it's cleaner to do it that way, for consistency.
	Include <sys/ioctl.h>, for FIONREAD.
	* systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
	This eliminates a problem whereby other files mysteriously had
	to include "syssignal.h" before including "systty.h" if they
	wanted to use "#ifdef SIGIO".

	This ports to platforms without HAVE_PTHREAD.

2012-09-06  Paul Eggert  <eggert@cs.ucla.edu>

	Signal-handler cleanup (Bug#12327).
	Emacs's signal handlers were written in the old 4.2BSD style with
	sigblock and sigmask and so forth, and this led to some
	inefficiencies and confusion.  Rewrite these to use
	pthread_sigmask etc. without copying signal sets around.  Also,
	get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
	'signal', and instead use functions that do not attempt to take
	over the system name space.  This patch causes Emacs's text
	segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
	* alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
	Do not include <signal.h> or "syssignal.h", as these
	modules do not use signals.
	* atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
	* gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
	Do not include <signal.h>, as "syssignal.h" does that for us now.
	* atimer.c (sigmask_atimers): New function.
	(block_atimers, unblock_atimers): New functions,
	replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
	All uses replaced.
	* conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
	no longer needed here.
	* emacs.c (main): Inspect existing signal handler with sigaction,
	so that there's	no need to block and unblock SIGHUP.
	* sysdep.c (struct save_signal): New member 'action', replacing
	old member 'handler'.
	(save_signal_handlers, restore_signal_handlers):
	Use sigaction instead of 'signal' to save and restore.
	(get_set_sighandler, set_sighandler) [!WINDOWSNT]:
	New function.  All users of 'signal' modified to use set_sighandler
	if they're writeonly, and to use sys_signal if they're read+write.
	(emacs_sigaction_init, forwarded_signal): New functions.
	(sys_signal): Remove.  All uses replaced by calls to sigaction
	and emacs_sigaction_init, or by direct calls to 'signal'.
	(sys_sigmask) [!__GNUC__]: Remove; no longer needed.
	(sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
	all uses replaced by pthread_sigmask etc. calls.
	* syssignal.h: Include <signal.h>.
	(emacs_sigaction_init, forwarded_signal): New decls.
	(SIGMASKTYPE): Remove.  All uses replaced by its definiens, sigset_t.
	(SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
	(sigmask, sys_sigmask): Remove; no longer needed.
	(sigpause): Remove.  All uses replaced by its definiens, sigsuspend.
	(sigblock, sigunblock, sigfree):
	(sigsetmask) [!defined sigsetmask]:
	Remove.  All uses replaced by pthread_sigmask.
	(signal): Remove.  Its remaining uses (with SIG_DFL and SIG_IGN)
	no longer need to be replaced, and its typical old uses
	are now done via emacs_sigaction_init and sigaction.
	(sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
	(sys_sigdel): Remove; unused.
	(NSIG): Remove a FIXME; the code's fine.  Remove an unnecessary ifdef.

	since special buffers aren't marked here any more.
	(allocate_buffer): Chain new buffer with all_buffers here...

	Be more systematic about preserving errno whenever a signal
	handler returns, even if it's not in the main thread.  Do this by
	renaming signal handlers to distinguish between signal delivery

	* process.c (handle_pipe_signal, handle_child_signal):
	New functions, with the actual signal-handling code taken from the
	original respective signal handlers, sans the sporadic attempts to
	preserve errno, since that's now done by handle_on_main_thread.
	* atimer.c (alarm_signal_handler): Remove unnecessary decl.
	* emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
	* emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:

	(main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
	Move initialization of main_thread to sysdep.c's init_signals.
	* process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
	our usage, and simplifies the mainline code.
	(record_child_status_change): New static function, as a helper
	for handle_child_signal, and with most of the old child handler's
	contents.
	(CAN_HANDLE_MULTIPLE_CHILDREN): New constant.

	replacing the old SIGNAL_THREAD_CHECK.  All uses changed.  This
	lets callers save and restore errno properly.

2012-09-04  Paul Eggert  <eggert@cs.ucla.edu>

	do most of the work.
	(fatal_error_backtrace): New function, taken from the guts
	of the old fatal_error_signal, but with a new option to output
	a backtrace.
	(shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
	info about the signal than just its number.
	* lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
	* sysdep.c: Include <execinfo.h>
	(emacs_backtrace): New function, taken partly from the previous

2012-09-04  Paul Eggert  <eggert@cs.ucla.edu>

	Simplify redefinition of 'abort' (Bug#12316).
	Do not try to redefine the 'abort' function.  Instead, redo
	the code so that it calls 'emacs_abort' rather than 'abort'.
	This removes the need for the NO_ABORT configure-time macro
	and makes it easier to change the abort code to do a backtrace.
	* .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
	* emacs.c (abort) [!DOS_NT && !NO_ABORT]:
	Remove; sysdep.c's emacs_abort now takes its place.
	* lisp.h (emacs_abort): New decl.  All calls from Emacs code to
	'abort' changed to use 'emacs_abort'.
	* msdos.c (dos_abort) [defined abort]: Remove; not used.
	(abort) [!defined abort]: Rename to ...
	(emacs_abort): ... new name.
	* sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
	the place of the old 'abort' in emacs.c.
	* w32.c, w32fns.c (abort): Do not #undef.
	* w32.c (emacs_abort): Rename from w32_abort.

2012-09-04  Eli Zaretskii  <eliz@gnu.org>

	* w32uniscribe.c (uniscribe_shape): Reverse the sign of
	offsets[j].dv, since the y axis of the screen coordinates points
	down, while the y axis of the font definition coordinates points
	up.  This fixes display of Arabic diacritics such as KASRA and
	KASRATAN.  (Bug#11860)

	Be more systematic about _setjmp vs setjmp.
	* alloc.c (test_setjmp, mark_stack):
	* image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
	(PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
	(png_load, my_error_exit, jpeg_load):
	* process.c (send_process_trap, send_process):
	Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
	The underscored versions are up to 30x faster on some hosts.
	Formerly, the code used setjmp+longjmp sometimes and
	_setjmp+_longjmp at other times, with no particular reason to
	prefer setjmp+longjmp.

	* process.c (read_process_output, exec_sentinel):
	Use bool for booleans.
	* emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
	All callers changed.
	* eval.c (interactive_p): Omit always-true boolean argument
	EXCLUDE_SUBRS_P.  All callers changed.
	* dispextern.h, lisp.h: Reflect above API changes.
	* firstfile.c (dummy): Use the address of 'main', whose signature
	won't change, instead of the address of 'initialize', whose
	signature just changed from int to bool.
	* lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
	* msdos.c (fatal_error_in_progress): ... from here.
	* xdisp.c (redisplaying_p): Now a boolean.  Set it to 1 instead
	of incrementing it.
	(redisplay_internal, unwind_redisplay): Simply clear
	REDISPLAYING_P when unwinding, instead of saving its previous,

	Clean up some extern decls.
	Mostly, this hoists extern decls out of .c files and into .h files.

629 630 631 632

	This fixes a performance regression introduced by the recent
	addition of vcopy.  This means 'vcopy' will need to be modified
	for a copying collector, but that's OK.  Also, tighten the
	checking in the assertion.
