--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Looks like we miss a pattern for
(insn 162 16 163 2 (set (subreg:V2DI (reg:DI 169) 0)
(vec_merge:V2DI (vec_duplicate:V2DI (reg:DI 101 [ ubound.0 ]))
(const_vector:V2DI [
(const_int 0 [0]) repeated x2
])
(const_int 1 [0x1]))) "t.f90":8:0 -1
(nil))
? I expected that this canonical form for movq gpr, %xmm is handled?
