--- Comment #7 from Hongtao Liu <liuhongt at gcc dot gnu.org> ---

> For arch=3Dcore-avx2, function returns in reg(cfun->returns_struct), but =
for
> "default" and resolver function, it returns in memory(cfun->returns_struct
> =3D=3D 1)
>=20
> The mismatch between resolver and dispatched function caused the ICE.

similar issue for

#include <immintrin.h>
__attribute__((target_clones ("avx512f", "default")))
__m512d foo(__m512d a, __m512d b)
{
      c =3D a + b;
}

with -O2, under avx512f, it returns in reg, by default it returns in memory=
