subroutine max_in_loop(rin, rout)
integer :: rin(1000), rout(1000), tmp
!real :: rin(1000), rout(1000), tmp
integer :: i
do i = 2, 1000
tmp = min(rin(i-1), rin(i))
rout(i) = tmp
end do
end subroutine
Is vectorized.
The floating point number makes it special in some way.
Looking in trans-intrinic.c , it is special.
/* FIXME: When the IEEE_ARITHMETIC module is implemented, the call to
__builtin_isnan might be made dependent on that module being loaded,
to help performance of programs that don't rely on IEEE semantics. */
