--- Comment #11 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I bet the culprit is that *rotl<mode>3_mask_dot has
(<MODE>mode =3D=3D Pmode || UINTVAL (operands[3]) <=3D 0x7fffffff)
in condition.  So, because *branch_anddi3_dot always wants DImode, if Pmode=
 is
SImode,
it should make sure (UINTVAL (operands[2]) << (63 - nb)) <=3D 0x7fffffff.=
