| | | | | | | | | | | | | | | | | | | | * 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.

| | | | | * alloc.c (sweep_vectors): Account total_vector_bytes for bool vectors larger than VBLOCK_BYTES_MAX.

| | | | | | | | | | | | | * lisp.h (make_pure_string): Fix prototype. (build_pure_c_string): New function, defined as static inline. This provides a better opportunity to optimize away calls to strlen when the function is called with compile-time constant argument. * alloc.c (make_pure_c_string): Fix comment.
