(BLOCK_ALIGN, BLOCK_BYTES, ABLOCKS_PADDING, ABLOCKS_SIZE)
(ABLOCKS_BYTES, ABLOCK_ABASE, ABLOCKS_BUSY, ABLOCKS_BASE): New macros.
(struct ablock, struct ablocks): New types.
(free_ablock): New global var.
(lisp_align_malloc, lisp_align_free): New functions.
(FLOAT_BLOCK_SIZE): Redefine in terms of BLOCK_BYTES.
(struct float_block): Reorder and add gcmarkbits.
(GETMARKBIT, SETMARKBIT, UNSETMARKBIT, FLOAT_BLOCK, FLOAT_INDEX)
(FLOAT_MARKED_P, FLOAT_MARK, FLOAT_UNMARK): New macros.
(init_float, make_float): Use lisp_align_malloc.
(free_float, live_float_p): Don't use `type' any more.
(make_float): Use FLOAT_UNMARK to access to mark bit.
(mark_maybe_object, mark_maybe_pointer, survives_gc_p):
Use FLOAT_MARKED_P to access the mark bit.
(pure_alloc): Simplify use of ALIGN.
(mark_object): Use FLOAT_MARK to access the mark bit.
(gc_sweep): Use new macros to access the float's mark bit.
(init_alloc_once): Init free_ablock.
beginning of the tutorial.
(Help-Inv): New node.
(Help-]): New node.
(Help-M): Systematically point out the differences between default
Emacs and stand-alone versions. Delete second menu.
(Help-Xref): Systematically point out the differences between default
Emacs and stand-alone versions.
(Help-Int): Change `l' example.
(Expert Info): Fix typos.
(Emacs Info Variables): Mention `Info-hide-note-references' and new
default for `Info-scroll-prefer-subnodes'.
variables to preserve array slices.
(gdb-array-slice): Rename gdb-mouse-array-slice.
(gdb-array-slice): Interactive function bound to "\r" for text
terminals.
(gdb-view-source): Rename gdb-view-source-function.
Set uninitialised variables (defvars) to nil.
(GC_STRING_BYTES): Don't mask markbit (it's only used on `size').
(allocate_buffer): Move.
(string_bytes): Don't mask markbit of `size_byte'.
(mark_maybe_object, mark_maybe_pointer, Fgarbage_collect)
(mark_object, mark_buffer, survives_gc_p, gc_sweep):
Use the `size' field of buffers (rather than the `name' field) for
the mark bit, as is done for all other vectorlike objects.
Use the new macros to access the mark bit of vectorlike objects.
