Sorry, making it "smarter" is what I meant by "fix it up".
My problem with it, as I mentioned in my previous note, is that
the only location it is currently called doesn't help me.
I guess what I was asking was there shouldn't be a problem
with me calling it from another location, correct?

H.J.,

Did you see my request to test the patch attached to:

  http://gcc.gnu.org/ml/gcc-patches/2008-02/msg01442.html

to verify I haven't changed x86/x86_64's SPEC scores due to
the rtlanal.c change?
