[Bug fortran/31593] Invariant DO loop variables and subroutines

[pinskia at gcc dot gnu dot org]

------- Comment #3 from pinskia at gcc dot gnu dot org  2007-04-16 23:12 -------
                call output (p1, p2, p3, p4)

That still clobbers p1, p2, p3, and p4 as they are passed by reference so is it
really undefined code if output changes the values for the do loop?
