--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Setting value number of vect__4.12_36 to { 255, 63, 15, 3, 255, 63, 15, 3, =
255,
63, 15, 3, 255, 63, 15, 3 } (changed)

Match-and-simplified VEC_PERM_EXPR <{ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0=
, 0,
0, 0 }, vect__4.12_36, { 0, 16, 1, 17, 2, 18, 3, 19, 4, 20, 5, 21, 6, 22, 7=
, 23
}> to { 0, 255, 0, 63, 0, 15, 0, 3, 0, 255, 0, 63, 0, 239, 0, 123 }

Confirmed that is definitely wrong. I don't even know where 239 and 123 came
