I can re-confirm that the patch moves 3.4 to the state of 3.3 - i.e. with an
extra imull compared to 2.95 and 4.0. The patch has bootstrapped with checking
enabled and -funroll-loops on ia64, testing is in process. I'll formally submit
the patch shortly.
For the imull regression I'll file a separate bug with a possibly reduced testcase.
