[Bug tree-optimization/28798] remove_phi_node attempts removal of a phi node resized by resize_phi_node

[pinskia at gcc dot gnu dot org]

------- Comment #2 from pinskia at gcc dot gnu dot org  2006-08-22 06:17 -------
We should never had needed resize_phi_node inside PRE and resize_phi_node also
does an exact replacement so that means you are keeping a reference to the old
PHI node when adding an edge which is wrong.
