--- Comment #25 from Richard Biener <rguenth at gcc dot gnu.org> --- OK, so the hashtable looks good. But 135 pre "insert iterations == 1084" 1 is indeed excessive. Expecially combined with 135 pre "Insertions" 3 I wonder if you can share the full -fdump-tree-pre-details dump (it's going to be large though).
