--- Comment #1 from Ira Rosen <irar at il dot ibm.com> 2010-12-25 11:49:58 UTC ---
The first loop now gets vectorized, it didn't because of:
/* Currently not vectorized because we get too many BBs in the inner-loop,
because the compiler doesn't realize that the inner-loop executes at
least once (cause k<4), and so there's no need to create a guard code
to skip the inner-loop in case it doesn't execute. */
So, the correct fix is to expect 2 outer loop vectorized on targets that
support realignment.
I'll fix the test.
