--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Hmm, looks like missed PRE of the COMPLEX_EXPR to me.
simplifying {complex_expr,_18,_19} translated 4 -> 3 to {complex_expr,_16,_17}
to _15
Starting insert iteration 1
Skipping partial redundancy for expression {complex_expr,_18,_19} (0003), no
redundancy on to be optimized for speed edge
indeed there's no redundancy on the speed edge and we'd end up splitting the
edge for the insertion on the speed edge.
