--- Comment #6 from tprince at computer dot org --- __sec_reduce_{min,max}_ind in Intel cilk(tm) plus don't give good performance, so one may suspect they are using size_t.(In reply to Jakub Jelinek from comment #5) > While this started with my commit, the actual bug is there from the start of > Cilk+ support. > The __sec_reduce_* builtins are declared with int return type, which doesn't > actual match what they return (it is in this case the type of the argument). > I bet the current way to deal with this is handle those in > resolve_overloaded_builtin and turn them into internal functions or > something similar and resolve the return type at that point. > The question is what to do with templates if the arguments are type > dependent. > Another thing that is weird is that the __sec_reduce_{min,max}_ind return > int, I would have expected size_t or something more appropriate for array > indexes. Does Cilk+ really mandate int in that case? How can it be used on > a very large array then?
