FPP 3.00Z36 will do exactly that.

Also, given A (N, M), B (N, M), C (N, M) and
      C = A + B
FPP will produce
      DO xxxxx J1X = 1, N*M
         C (J1X, 1) = A (J1X, 1) + B (J1X, 1)
xxxxx CONTINUE

I love it when compilers get better.  But I do have CONVEX-envy when it
comes to some constructs that the CRAY compiler still won't attempt.
