What do you think should happen when the user passes an unrolling factor of 0 or 1? After looking at other fortran compilers, I think the unrolling factor should be forced when N>1, and when N is 0 or 1 we should disable unroll (and jam). If you agree, would you mind updating this directive handling? Thanks!
