Jan Hubicka <hubicka at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Last reconfirmed|2015-03-13 00:00:00 |2015-4-30 --- Comment #5 from Jan Hubicka <hubicka at gcc dot gnu.org> --- Still ICE during LTObootstrap on PPC64 (gcc110). I will try to at least figure out what goes wrong with the PHI (if it is wrong control dependency due to critical edge or something else) I suppose we can relax the check to: degenerate_phi_p (phi) || SSA_NAME_OCCURS_IN_ABNORMAL_PHI (gimple_phi_result (phi) but we may need to trigger SSA rewrite on resulting code as cddce will break dominance conditions on the PHI.
