--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Seems to be a simplify-rtx.c bug.
simplify_binary_operation (IOR, V4SImode, (ne:V4SI (reg:V4SI 82 [ v.0_2 ])
(reg:V4SI 83 [ _4 ])), (eq:V4SI (reg:V4SI 82 [ v.0_2 ]) (reg:V4SI 83 [ _4 ]=
)))
returns (const_int 1 [0x1]), which is wrong.=
