--- Comment #12 from Jonathan Wakely <redi at gcc dot gnu.org> ---
We still don't have code to make this more efficient (that would be Bug 100070)
but the correct way to construct a vector from iota_view is C++23's
std::ranges::to
Adding this function:
__attribute__((noinline)) std::vector<int> fn3(int n)
{
return std::ranges::to<std::vector<int>>(std::ranges::iota_view{0, n});
}
And then calling it from main() I get:
3678697
35870273
3000809
So this is significantly better than the naive loop.
