--- Comment #19 from janus at gcc dot gnu.org --- (In reply to Steve Kargl from comment #17) > Then you are only interest in the special case of .and. > > binop above is the entire collection of all binary > operators (e.g., +,-,*,/ etc as well as .and.). The original problem of ill-posed short-circuiting does not apply to all binary operators, but only to things like: * X = .false. .and. Y() * X = .true. .or. Y() and possibly: * X = 0 * Y() * X = 0 / Y() (in case gfortran applies 'short-circuiting' for such cases, which I haven't checked). There might be other cases as well, but it certainly does not apply to + and -. > The order of the evaluation of ping() and pong() is > not specified by the Fortran standard. This PR is not about reordering, but about short-circuiting.
