!The loop in this example cannot be parallelized.
!
!This pattern has two pair of dependencies:
!1. loop carried output dependence
! x = .. :
!
!2. loop carried true dependence due to:
!.. = x;
! x = ..;
!Data race pairs: we allow two pairs to preserve the original code pattern.
! 1. x@48 vs. x@49
! 2. x@49 vs. x@49
