This is based on a proposal by YAMAMOTO Mitsuharu in <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>. For an admittedly artificial (nth 8000 longlist) benchmark on Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks Emacs's overall text size by 1%. * lisp.h (XUNTAG): New macro. (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW) (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR) (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it. * eval.c (Fautoload): * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT): * frame.h (XFRAME): Use XUNTAG.
