--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
I suppose it's
di_result[0] += si_result[0];
di_result[1] += si_result[1];
on x86 we do
vect__5.11_99 = (vector(2) long long int) _100;
vect__6.12_98 = _29 + vect__5.11_99;
as we have a extendv2siv2di pattern. It's probably easier to try reproducing
with a testcase not involving varargs but {di,si}_result initialized from
incoming parameters?
