--- Comment #6 from Ehsan Amiri <amehsan at ca.ibm.com> ---
The problem still exists for some simple loops such as this:

      for( i = 0 ; i < n ; i++ )
      {
         a[i] += b[i] + d[i];;
      }
(all array data types float)

again SCEV is unable to compute the iteration count of the loop: (from debug
output):

Exit Count for Loop at depth 1 containing: %vector.body<header><latch><exiting>
 from block vector.body: ***COULDNOTCOMPUTE***
