D38632: Add anti- and output loop carried dependences in SwingScheduler

[Ning XIE via llvm-commits]

Hi Brendon,


I have a simple test case that has an anti- loop carry dependence:


void foo (int n, int *__restrict a, int *__restrict b) {

  int i;

  for (i = 0; i < n-1; ++i) {

    a[i] = i + 1;

    b[i] = a[i] + a[i-1];

  }

}


I tested with output dependence as well: there will be a order dependence added.


Thanks.


Best,

Ning

Thanks for adding this functionality.  I'll take a look.  Do you happen to have a test case?

Thanks,
Brendon
