--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
This seems to be infinite recursion in subst/combine_simplify_rtx on
expression:
(plus:SI (ltu:SI (plus:SI (if_then_else:SI (eq (reg:CC 180)
                    (const_int 0 [0]))
                (reg:SI 155 [ _1+-3 ])
                (reg:SI 175 [ vu+4 ]))
            (reg:SI 155 [ _1+-3 ]))
        (if_then_else:SI (eq (reg:CC 180)
                (const_int 0 [0]))
            (reg:SI 155 [ _1+-3 ])
            (reg:SI 175 [ vu+4 ])))
    (reg:SI 174 [ vu ]))
The subst is from (pc) to (pc), i.e. simplification.
