--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Maybe one of richi's recent SLP related patches:

GCC 13:
/app/example.cpp:5:21: missed:   Build SLP failed: not grouped load _12 =3D=
 *_11;
/app/example.cpp:5:21: note:   SLP discovery for node 0x4cdbb68 failed
/app/example.cpp:5:21: note:   SLP discovery for node 0x4cdbae8 failed
/app/example.cpp:5:21: note:   SLP discovery failed

But GCC 14:
/app/example.cpp:5:21: note:   Build SLP for _6 =3D *_5;
/app/example.cpp:5:21: note:   precomputed vectype: vector(4) int
/app/example.cpp:5:21: note:   nunits =3D 4
/app/example.cpp:5:21: note:   SLP discovery for node 0x4802428 succeeded=
