(Fgarbage_collect, mark_object): Ignore the markbit.
|

avoid warning.

allocating ablocks, which also avoids freeing a pointer into an
ablocks structure.
|
|
|
|
(GC_STRING_CHARS, string_bytes): Use ARRAY_MARK_FLAG rather than
MARKBIT as the gcmarkbit for strings.
|
|
|
|
(init_float, init_cons): Let the normal code allocate the first block.
(CONS_BLOCK_SIZE): Redefine based on BLOCK_BYTES and bitmap size.
(CONS_BLOCK, CONS_INDEX, CONS_MARKED_P, CONS_MARK, CONS_UNMARK): New macros.
(struct cons_block): Move conses to the beginning. Add gcmarkbits.
(Fcons): Use lisp_align_malloc and CONS_UNMARK.
(live_cons_p): Check the pointer is not past the `conses' array.
(mark_maybe_object, mark_maybe_pointer): Use CONS_MARKED_P.
(mark_object, mark_buffer): Use CONS_MARKED_P and CONS_MARK.
(survives_gc_p): Use CONS_MARKED_P and simplify.
(gc_sweep): Use CONS_MARKED_P, CONS_UNMARK, and lisp_align_free.

not put into BSS by that optimization.
|
|
(lisp_align_malloc): Use posix_memalign is available.
(ABLOCKS_BASE): Use HAVE_POSIX_MEMALIGN as an optimization.
(STRING_BLOCK_SIZE): Rename from STRINGS_IN_STRING_BLOCK for consistency.
Update users.
|
|
(mark_buffer): Manually mark the overlays_(after|before) fields.
|
|
|
|
now that `floats' is not the last element of the struct any more.
|
|
(last_marked): Change accordingly.
(mark_interval, mark_maybe_object, mark_maybe_pointer)
(Fgarbage_collect, mark_glyph_matrix, mark_face_cache, mark_image)
(mark_buffer): Update calls to mark_object.

(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.

(gc_sweep): Use new macros to access the float's mark bit.
(init_alloc_once): Init free_ablock.
|
|
|
|
(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.
|
|
(Fmake_marker, free_marker, gc_sweep): Update for new types.
|
|
Initialize the new field `gcmarkbit'.
(mark_interval, MARK_INTERVAL_TREE): Use the new `gcmarkbit' field.
(mark_interval_tree): Don't mark the tree separately from the nodes.
(UNMARK_BALANCE_INTERVALS): Don't unmark the tree.
(mark_maybe_object, mark_maybe_pointer, Fgarbage_collect, mark_object)
(survives_gc_p, gc_sweep): Use new `gcmarkbit' fields.

CONTENTS.
(make_specified_string): Likewise.

(Fgarbage_collect): Use them.

(mark_maybe_object) [GC_MARK_STACK==GC_USE_GCPROS_CHECK_ZOMBIES]:
Fix assignment of zombies.
(Fgarbage_collect) [GC_MARK_STACK==GC_USE_GCPROS_CHECK_ZOMBIES]:
Don't take car of non-cons.

adjusting the pointer. Use a goto to handle overflow exception.
