* alloc.c (enum mem_type): New memory type.
(refill_memory_reserve): Use new type for spare memory.
This prevents live_cons_p and live_string_p from incorrect
detection of uninitialized objects from spare memory as live.
Merge from gnulib, incorporating:
2012-08-24 execinfo: port to FreeBSD
2012-08-22 execinfo: new module
* admin/merge-gnulib (GNULIB_MODULES): Add execinfo.

(die) [ENABLE_CHECKING]: Print a backtrace if available.
* src/Makefile.in (LIB_EXECINFO): New macro.
(LIBES): Use it.
* buffer.c (set_buffer_overlays_before): Move here from buffer.h,
and rename from buffer_overlays_set_before.
(set_buffer_overlays_after): Move here from buffer.h, and rename
from buffer_overlays_set_after.
* buffer.h (buffer_intervals): Rename from buffer_get_intervals.
All uses changed.

interval_set_right.
(copy_interval_parent): Move here from intervals.h, and rename from
interval_copy_parent.
* intervals.h (set_interval_parent): Rename from interval_set_parent.
(set_interval_plist): Rename from interval_set_plist.
Return void, not Lisp_Object, since no caller uses the result.
* lisp.h (string_intervals): Rename from string_get_intervals.
(set_string_intervals): Rename from string_set_intervals.
* src/lisp.h (struct Lisp_Symbol): Change xname to meaningful
name since all xname users are fixed long time ago. Do not use
INTERNAL_FIELD.
(set_symbol_name, set_symbol_function, set_symbol_plist):
(set_symbol_next, set_overlay_plist): New function.
(struct Lisp_Cons): Do not use INTERNAL_FIELD.
(struct Lisp_Overlay): Likewise.
(CVAR, MVAR, SVAR): Remove.
* src/alloc.c, src/buffer.c, src/buffer.h, src/bytecode.c:

Remove.
* alloc.c (XMALLOC_HEADER_ALIGNMENT, roundup_size):
(union aligned_Lisp_Symbol, union aligned_Lisp_Misc):
(mark_maybe_pointer, pure_alloc): Change to use GCALIGNMENT.
These casts are no longer needed now that we assume C89 or later,
since they involve casting to or from void *.
* alloc.c (make_pure_string, make_pure_c_string, pure_cons)
(make_pure_float, make_pure_vector):
* lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):
* macros.c (Fstart_kbd_macro):
* menu.c (find_and_return_menu_selection):
* minibuf.c (read_minibuf_noninteractive):
* sysdep.c (closedir):
* xdisp.c (x_produce_glyphs):
* xfaces.c (compare_fonts_by_sort_order):
* xfns.c (x_real_positions, select_visual):

Remove unnecessary pointer casts.
* alloc.c (record_xmalloc): New function.
* lisp.h (record_xmalloc): New decl.
(SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
more like a function. This is because the pointer cast is not
needed. All uses changed.
* print.c (print_string, print_error_message): Avoid length recalc.
* src/lisp.h (struct Lisp_Cons): Use INTERNAL_FIELD.
Remove obsolete comment.
(MVAR): New macro.
(struct Lisp_Overlay): Use INTERNAL_FIELD.

access to Lisp_Object members of struct Lisp_Overlay to MVAR.
* alloc.c (gdb_make_enums_visible) [USE_LSB_TAG]: Add lsb_bits.
* lisp.h (enum lsb_bits) [USE_LSB_TAG]: New enum, for
gdb_make_enums_visible.
(TYPEMASK, VALMASK) [USE_LSB_TAGS]: Now enum constants, not macros.
(DIRECTORY_SEP): Now a constant, not a macro.
* lisp.h (min, max): Move earlier, because they're used earlier now.
(INTMASK, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK)
(CHAR_TABLE_STANDARD_SLOTS, CHARTAB_SIZE_BITS_0)
(CHARTAB_SIZE_BITS_1, CHARTAB_SIZE_BITS_2, CHARTAB_SIZE_BITS_3)
(DEFAULT_HASH_SIZE, COMPILED_ARGLIST, COMPILED_BYTECODE)
(COMPILED_CONSTANTS, COMPILED_STACK_DEPTH, COMPILED_DOC_STRING)
(COMPILED_INTERACTIVE, CHAR_ALT, CHAR_SUPER, CHAR_HYPER, CHAR_SHIFT)
(CHAR_CTL, CHAR_META, CHAR_MODIFIER_MASK, CHARACTERBITS)
(MANY, UNEVALLED, FLOAT_TO_STRING_BUFSIZE, MAX_ALLOCA):
Now constants, for GDB. They need not be macros.
(MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM, STRING_BYTES_BOUND):
Now constants, for GDB, as well as macros, for static initializers.
(CHAR_TABLE_STANDARD_SLOTS, CHAR_TABLE_EXTRA_SLOTS):
Move to after the definition of struct Lisp_Char_Table,
since the former now needs that type defined.
(enum CHARTAB_SIZE_BITS, enum CHAR_TABLE_STANDARD_SLOTS)
(enum DEFAULT_HASH_SIZE, enum Lisp_Compiled, enum char_bits)
(enum maxargs, enum FLOAT_TO_STRING_BUFSIZE, enum MAX_ALLOCA):
New enums, for gdb_make_enums_visible.
(GLYPH_MODE_LINE_FACE): Remove; unused.
* alloc.c (STRING_BYTES_MAX): Now a constant, now a macro.
(gdb_make_enums_visible): Add enum CHARTAB_SIZE_BITS, enum
CHAR_TABLE_STANDARD_SLOTS, enum char_bits, enum DEFAULT_HASH_SIZE,
enum FLOAT_TO_STRING_BUFSIZE, enum Lisp_Bits, enum Lisp_Compiled,
enum maxargs, enum MAX_ALLOCA.
(ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): Remove.
(ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Remove;
no longer needed, now that they are done in lisp.h.
* alloc.c (GC_STRING_BYTES, CHECK_STRING_BYTES): Remove. Convert
all users to STRING_BYTES or string_bytes if GC_CHECK_STRING_BYTES.
(check_string_bytes): Define to empty if not GC_CHECK_STRING_BYTES.
(check_sblock, compact_small_strings): Simplify.
* .bzrignore: Add lib/stdalign.h.
* config.bat: Do not set NO_DECL_ALIGN; no longer needed.
Copy lib/stdalign.in.h to lib/stdalign.in-h as needed.
* configure.ac (HAVE_ATTRIBUTE_ALIGNED): Remove the code that
fiddles with this, as gnulib now does this for us.
* admin/merge-gnulib: Add environ, stdalign.
* m4/environ.m4: New file, from gnulib.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* lib/stdalign.in.h, m4/stdalign.m4: New files, from gnulib.
* sed2v2.inp (HAVE_ATTRIBUTE_ALIGNED): Remove edit.
* sedlibmk.inp (STDALIGN_H, @GL_GENERATE_STDALIGN_H_TRUE@)
(GL_GENERATE_STDALIGN_H_FALSE): New edits.
* nt/config.nt (HAVE_ATTRIBUTE_ALIGNED): Remove.
* src/alloc.c (XMALLOC_BASE_ALIGNMENT, GC_POINTER_ALIGNMENT, pure_alloc):
Simplify by using alignof.

* src/lisp.h: Include <stdalign.h>.
(GCALIGNMENT): New macro and constant.
(DECL_ALIGN): Remove. All uses replaced by alignas (GCALIGNMENT).
(USE_LSB_TAG): ifdef on alignas, not on DECL_ALIGN.
(stdalign): New macro, if not already defined.
src/lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
enumeration constants, as PURE and HEAP are too general, and clash
with other headers and sources, such as gmalloc.c and the
MS-Windows system headers. All users changed.
* .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
arms of an 'if', not using conditional expressions; otherwise GDB
complains about the types in the unevaluated arm when the argument
is an integer literal.
(xgetint): Simplify expression.
* alloc.c (gdb_make_enums_visible): New constant. This ports to
GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
Zaretskii in <http://bugs.gnu.org/1995-05-30T23:07:27Z!kwzh@gnu.org#13>.
* lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
needed now that we have gdb_make_enums_visible.
(enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
(enum enum_USE_LSB_TAG):
New enum types, packaging up enums that need to be exported to GDB.
* lisp.h (struct Lisp_Excursion): New data type.
(PVEC_EXCURSION): New pseudovector type.
(XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
to deal with it. Adjust comments.
(init_marker, attach_marker): New prototype.
(unchain_marker): Adjust prototype.
* marker.c (attach_marker): Change to global.
(init_marker): New function.
* alloc.c (Fmake_marker, build_marker): Use it.
(build_marker): More easserts.
(mark_object): Handle struct Lisp_Excursion.
* editfns.c (save_excursion_save, save_excursion_restore):
Reimplement to use struct Lisp_Excursion. Add comments.
* alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
(ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
emacs.c, as this is a more-suitable home. Had this been done earlier
the fix for 1995-05-30T23:07:27Z!kwzh@gnu.org would have avoided some of the problems noted in
<http://bugs.gnu.org/1995-05-30T23:07:27Z!kwzh@gnu.org#13> by Eli Zaretskii, as the scope problems
would have been more obvious.
* emacs.c (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
(gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
(CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
Remove; now done in lisp.h.
* lisp.h (PUBLISH_TO_GDB): New macro.
(GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
(DATA_SEG_BITS): Use it.
(GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
(CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
* mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
not be usable in #if. This simplifies things.
* alloc.c (GC_DEFAULT_THRESHOLD): New macro.
(Fgarbage_collect): Use it. Change minimum to 1/10 of default.
(free_cons, free_misc): Subtract object size from consing_since_gc.
(FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
'for_each_per_buffer_object_at'.
All uses changed. It's better to use upper-case for macros that
cannot be implemented as functions, to give the reader a clue
that they're special.
* alloc.c (bool_header_size): New constant.
(header_size, word_size): Move earlier, as they're now used earlier.
Use 'word_size' in a few more places, where it's appropriate.
(Fmake_bool_vector, sweep_vectors): Don't assume that there is no
padding before the data member of a bool vector.
(sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
than doing the check by hand with an abort ().
