+
+       Shrink struct vectorlike_header to the only size field.
+       * lisp.h (enum pvec_type): Avoid explicit enum member values.
+       Adjust comment.
+       (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
+       PVEC_TYPE_MASK to arrange new bitfield in the vector header.
+       (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
+       (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
+       information from the vector header.  Adjust comment.
+       (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
+       (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
+       layout.
+       (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.
+       (struct vectorlike_header): Remove next member.  Adjust comment.
+       (struct Lisp_Subr): Add convenient header.  Adjust comment.
+       (allocate_pseudovector): Adjust prototype.
+       * alloc.c (mark_glyph_matrix, mark_face_cache, allocate_string)
+       (sweep_string, lisp_malloc): Remove useless prototypes.
+       (enum mem_type): Adjust comment.
+       (NEXT_IN_FREE_LIST): New macro.
+       (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
+       (Fmake_bool_vector): Likewise.
+       (struct large_vector): New type to represent allocation unit for
+       the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
+       (large_vectors): Change type to struct large_vector.
+       (allocate_vector_from_block): Simplify.
+       (PSEUDOVECTOR_NBYTES): Replace with...
+       (vector_nbytes): ...new function.  Adjust users.
+       (sweep_vectors): Adjust processing of large vectors.
+       (allocate_vectorlike): Likewise.
+       (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
+       Add easserts.  Adjust XSETPVECTYPESIZE usage.
+       (allocate_buffer): Use BUFFER_PVEC_INIT.
+       (live_vector_p): Adjust to match large vector.
+       * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
+       * buffer.h (struct buffer): Add next member.
+       (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
+       New macros.
+       (FOR_EACH_BUFFER): Adjust to match struct buffer change.
+       * fns.c (internal_equal): Adjust to match enum pvec_type change.
+       (copy_hash_table): Adjust to match vector header change.
+       * lread.c (defsubr): Use XSETPVECTYPE.
+       * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
+       (xvectype): Likewise.  Print PVEC_NORMAL_VECTOR for regular vectors.
+       (xvecsize): New command.
