--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Seems it is combine_simplify_rtx called with x:
(plus:SI (ltu:SI (plus:SI (if_then_else:SI (eq (reg:CC 147)
                    (const_int 0 [0]))
                (subreg:SI (reg:DI 126) 4)
                (reg:SI 146))
            (subreg:SI (reg:DI 126) 4))
        (if_then_else:SI (eq (reg:CC 147)
                (const_int 0 [0]))
            (subreg:SI (reg:DI 126) 4)
            (reg:SI 146)))
    (reg:SI 133 [ iftmp.0_2 ]))
and from == to == pc_rtx.
