[Bug middle-end/29256] [4.2/4.3/4.4 regression] loop performance regression



------- Comment #26 from rakdver at gcc dot gnu dot org  2008-08-06 21:51 -------
Created an attachment (id=16036)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=16036&action=view)
possible fix

One place where this can be fixed is fwprop (something like the attached
patch).  I am not sure whether it is the right place, though; maybe cse should
be handling this?
