+
+ 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.

+
+ * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
+ 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.

+
+ * nsterm.m (ns_update_begin): Set clip path to whole view by using
+ NSBezierPath (Bug#12131).

+
+ * fns.c (Fdelq, Fdelete): Doc fix.

+
+ * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
+ (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
+
+2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
+
+ * lisp.h (make_lisp_ptr): New macro to replace XSET.
+ (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
+ Use it.

+
+ * 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.
+
+ * 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.

+
+ * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
+ compositeToPoint for OSX < 10.6 (Bug#12390).
+
+2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
+
+ * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
+ This produces more-accurate results.
+
+2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
+
+ * nsterm.m (updateFrameSize): Call setFrame: on the view when size
+ changes (Bug#12088).

+ * syntax.c (Fstring_to_syntax): Doc fix.
+
