------- Comment #23 from rguenth at gcc dot gnu dot org 2007-08-30 09:07 -------
I don't think the patch fixes anything. Can you elaborate on
"D.8892_26 is a non-pointer variable, eliminating edges."
but D.8892 _is_ a pointer. Or is it just that D.8892_26 is ultimately copied
from a pointer that doesn't have a constraint? (because it is initialized
from a call, this is what the patch would "fix" - it creates a lot more NMTs
and (by luck?) sees that now, even if with and without the patch D.8895_29
and __tmp_27 point to anything, they may point to the same thing)
