--- Comment #14 from Richard Biener <rguenth at gcc dot gnu.org> ---
We could implement __builtin_ variants with a different ABI, returning the
quotiend and remainder in a (GCC extension) _Complex int type. The library
would then do
#define div(a, b) ({ div_t res; _Complex int r = __builtin_div(a,b); res.quot =
_Real r; res.rem = _Imag r; res; })
that's without an inline function. It's also way nicer to GCC internally,
not requiring memory for the return value - we'd have to lower to this kind
of internal code anyways to make code-generation good.
