* 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.
