I guess some of the arithmetic operations at various places can be removed to shorten the test. Like for e.g:

  %65 = arith.subi %64, %c1 : index
  %66 = arith.muli %5, %65 : index
  %67 = arith.addi %66, %62 : index

I am OK with creating a ticket to reduce the test later and proceeding. Please wait for Mehdi.
