If a nonvolatile local variable is written before a _longjmp to
the frame containing the variable, and is read after the _longjmp,
the value read is indeterminate. Some local variables of type
'struct handler' and 'struct catchtag' are used in this way, so
mark each of their slots as volatile if the slot can be set before
_longjmp and read afterwards.
* lisp.h (struct handler): var and chosen_clause are now volatile.
(struct catchtag): val, next, and pdlcount are now volatile.
* lib-src/pop.c (socket_connection) [HAVE_GETADDRINFO]:
* src/bidi.c (bidi_push_it, bidi_pop_it):
* src/fns.c (copy_hash_table):
* src/image.c (define_image_type):
* src/keyboard.c (kbd_buffer_store_event_hold):
* src/process.c (Fprocess_send_eof):
* src/xfaces.c (x_create_gc) [HAVE_NS]:
* src/xgselect.c (xg_select):
Use assignment, not memcpy, as either will do here, and assignment is
more likely to catch type errors.
Use pointer-to-a-pointer to simplify and avoid a NILP check each
time an item is removed. No need to mark this function 'inline';
the compiler knows better than we do.
* nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
(updateFrameSize:): Add delay parameter to updateFrameSize, send it
to change_frame_size.
(windowDidResize:): Pass YES to updateFrameSize.

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.
* Makefile.in (install-arch-dep, install-arch-indep, install-doc):
Be more explicit about dependencies, for parallel `make install'.
It is not so unreasonable to run `make -j# install' from a clean state
for a self-contained NS build, where the "installation" happens within
the build tree.
The porting part of this patch fixes bugs on non-IEEE platforms
with frexp, ldexp, logb.
* admin/CPP-DEFINES (HAVE_CBRT, HAVE_LOGB, logb): Remove.
* configure.ac (logb, cbrt): Do not check for these functions,
as they are not being used.
* doc/lispref/numbers.texi (Float Basics, Arithmetic Operations, Math Functions):
Document that / and mod (with floating point arguments), along
with asin, acos, log, log10, expt and sqrt, return special values
instead of signaling exceptions.
(Float Basics): Document that logb operates on the absolute value
of its argument.
(Math Functions): Document that (log ARG BASE) also returns NaN if
BASE is negative. Document that (expt X Y) returns NaN if X is a
finite negative number and Y a finite non-integer.
* etc/NEWS: Document NaNs versus signaling-error change.
* src/data.c, src/lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
Now static.
* src/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.
Run autogen.sh after bootstrap-clean, to avoid bzr pull issues.
* INSTALL, README: Document autogen.sh.
* Makefile.in (Makefile): Mark it as precious, since it's updated
atomically.
(MAKE_CONFIG_STATUS): New macro.
(config.status, bootstrap): Use it. This causes 'make bootstrap'
to run config.status with the --recheck option, which is more
appropriate for a bootstrap.
(bootstrap): Run autogen.sh right after cleaning. Don't worry
about failures due to missing tools.
* autogen.sh: Exit with status 101 when failing due to missing tools.
* make-dist: Distribute autogen.sh.

(replace-lax-whitespace, query-replace-regexp)
(query-replace-regexp-eval, replace-regexp): Doc fix.
(perform-replace, replace-highlight): Let-bind
isearch-lax-whitespace to replace-lax-whitespace and
isearch-regexp-lax-whitespace to replace-regexp-lax-whitespace.
* lisp/isearch.el (isearch-query-replace): Let-bind
replace-lax-whitespace to isearch-lax-whitespace and
replace-regexp-lax-whitespace to
isearch-regexp-lax-whitespace.
Fixes: debbugs:10885
src/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.
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.
* configure.ac (frexp, fmod): Remove checks for these functions,
as we now assume them.
(FLOAT_CHECK_DOMAIN, HAVE_INVERSE_HYPERBOLIC, NO_MATHERR)
(HAVE_EXCEPTION):
Remove; no longer needed.
* admin/CPP-DEFINES (HAVE_FMOD, HAVE_FREXP, FLOAT_CHECK_DOMAIN)
(HAVE_INVERSE_HYPERBOLIC, NO_MATHERR): Remove.
* src/data.c, src/image.c, src/lread.c, src/print.c:
Don't include <math.h>; no longer needed.
* src/data.c, src/floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
might be autoconfigured, as that never happens.
* src/data.c (fmod):
* src/doprnt.c (DBL_MAX_10_EXP):
* src/print.c (DBL_DIG):
Remove. C89 or later always defines these.
* src/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.
* lisp/replace.el (query-replace-map): Bind four new symbols for
requesting window scrolling.
* lisp/subr.el (y-or-n-p): Handle the window-scrolling bindings in
query-replace-map.
* lisp/custom.el (custom-theme-load-confirm): Use y-or-n-p.
* lisp/window.el (scroll-other-window-down): Make the arg optional.
* lisp/emacs-lisp/map-ynp.el (map-y-or-n-p): Don't bind scrolling keys
since they are now in query-replace-map.
* doc/lispref/minibuf.texi (Yes-or-No Queries): Document recentering and
scrolling in y-or-n-p. Remove gratuitous example.
* doc/lispref/searching.texi (Search and Replace): Document window scrolling
entries in query-replace-map.

not just expect to be at its beginning. Adjust callees.
Succeed when do-end block has no space before the pipe character.
(ruby-brace-to-do-end): When the original block is one-liner,
convert to multiline. Reindent the result.
* test/automated/ruby-mode-tests.el:
(ruby-toggle-block-to-multiline): New test.
(ruby-should-indent-buffer, ruby-toggle-block-to-do-end)
(ruby-toggle-block-to-brace): Use buffer-string.
if register contains text so that `C-x r +' can now be
used for appending to a text register.
(register): New group.
(register-separator): New user option.
(append-to-register, prepend-to-register): Add separator based on
`register-separator.
* doc/emacs/regs.texi (Text Registers): `C-x r +' can now be used instead of
M-x append-to-register. New option `register-separator'.
(Number Registers): Mention that `C-x r +' is polymorphic.
