+ * bidi.c: Integer signedness and overflow fixes.
+ (bidi_cache_idx, bidi_cache_last_idx, bidi_cache_fetch_state)
+ (bidi_cache_search, bidi_cache_find_level_change)
+ (bidi_cache_iterator_state, bidi_cache_find, bidi_find_other_level_edge)
+ (bidi_dump_cached_states):
+ Don't arbitrarily limit cache indexes to int; use ptrdiff_t instead.
+ (bidi_cache_size): Use ptrdiff_t rather than size_t, as we prefer
+ signed integers.
+ (elsz): Make it a (signed) constant.
+ (bidi_cache_iterator_state): Check for size-calculation overflow.
+
+ * alloc.c: Integer signedness and overflow fixes.
+ Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
+ (__malloc_size_t): Default to size_t, not to int.
+ (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
+ (Fgarbage_collect, mark_object_loop_halt, mark_object):
+ Prefer ptrdiff_t to size_t when either would do, as we prefer
+ signed integers.
+ (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
+ (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
+ Now const. Initialize with values that are in range even if char
+ is signed.
+ (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
+ (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
+ These functions do the right thing with sizes > 2**32.
+ (check_depth): Now ptrdiff_t, not int.
+ (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
+ Adjust to new way of storing sizes. Check for size overflow bugs
+ in rest of code.
+ (STRING_BYTES_MAX): Adjust to new overheads. The old code was
+ slightly wrong anyway, as it missed one instance of
+ XMALLOC_OVERRUN_CHECK_OVERHEAD.
+ (refill_memory_reserve): Omit needless cast to size_t.
+ (mark_object_loop_halt): Mark as externally visible.
+
+ * xselect.c: Integer signedness and overflow fixes.
+ (Fx_register_dnd_atom, x_handle_dnd_message):
+ Use ptrdiff_t, not size_t, since we prefer signed.
+ (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
+ * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
+ x_dnd_atoms_size and x_dnd_atoms_length.
+
+ * doprnt.c: Prefer signed to unsigned when either works.
+ * eval.c (verror):
+ * doprnt.c (doprnt):
+ * lisp.h (doprnt):
+ * xdisp.c (vmessage):
+ Use ptrdiff_t, not size_t, when using or implementing doprnt,
+ since the sizes cannot exceed ptrdiff_t bounds anyway, and we
+ prefer signed arithmetic to avoid comparison confusion.
+ * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
+ but is a bit tricky.
+
+ Assume freestanding C89 headers, string.h, stdlib.h.
+ * data.c, doprnt.c, floatfns.c, print.c:
+ Include float.h unconditionally.
+ * gmalloc.c: Assume C89-at-least behavior for preprocessor,
+ limits.h, stddef.h, string.h. Use memset instead of 'flood'.
+ * regex.c: Likewise for stddef.h, string.h.
+ (ISASCII): Remove; can assume it returns 1 now. All uses removed.
+ * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
+ * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
+ (STDC_HEADERS): Remove obsolete defines.
+ * sysdep.c: Include limits.h unconditionally.
+
+2011-07-06 Paul Eggert <eggert@cs.ucla.edu>
+
+ Assume support for memcmp, memcpy, memmove, memset.
+ * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
+ * regex.c (memcmp, memcpy):
+ Remove; we assume C89 now.
+
+ * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
+ (__malloc_safe_bcopy): Remove; no longer needed.
+
+ * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
+ Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
+ well either way, and we prefer signed to unsigned.
+
+2011-07-06 Paul Eggert <eggert@cs.ucla.edu>
+
+ Remove unportable assumption about struct layout (Bug#8884).
+ * alloc.c (mark_buffer):
+ * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
+ (clone_per_buffer_values): Don't assume that
+ sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
+ This isn't true in general, and it's particularly not true
+ if Emacs is configured with --with-wide-int.
+ * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
+ New macros, used in the buffer.c change.

+ Move inside HAVE_XFT.
+ (something_changed_gsettingsCB): Renamed from something_changedCB.
+ Check for changes in GSETTINGS_TOOL_BAR_STYLE and GSETTINGS_FONT_NAME
+ also.
+ (GCONF_TOOL_BAR_STYLE, GCONF_FONT_NAME): New defines.
+ (GCONF_MONO_FONT): Renamed from SYSTEM_MONO_FONT. Move inside HAVE_XFT.

+ comment.

+
+ Random fixes. E.g., (random) never returned negative values.
+ * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
+ subseconds part to the entropy, as that's a bit more random.
+ Prefer signed to unsigned, since the signedness doesn't matter and
+ in general we prefer signed. When given a limit, use a
+ denominator equal to INTMASK + 1, not to VALMASK + 1, because the
+ latter isn't right if USE_2_TAGS_FOR_INTS.
+ * sysdep.c (get_random): Return a value in the range 0..INTMASK,
+ not 0..VALMASK. Don't discard "excess" bits that random () returns.
+
+2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
+
+ * textprop.c (text_property_stickiness):
+ Obey Vtext_property_default_nonsticky.
+ (syms_of_textprop): Add `display' to Vtext_property_default_nonsticky.
+ * w32fns.c (syms_of_w32fns):
+ * xfns.c (syms_of_xfns): Don't Add `display' since it's there by default.
