--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Let me reword the summary. what you want is div and ldiv and imaxdiv to be
supported as a builtin, in that it expands correctly to do the div/mod inlined.
>The goal is that std::div and cstdlib's div can be reimplemented as calling

Or rather they stay the way they are and GCC rewrites it to be correct. AKA no
reimplementing at all.
