--- Comment #3 from Tamar Christina <tnfchris at gcc dot gnu.org> --- (In reply to Richard Biener from comment #2) > For the epilog LC-SSA we lack the correct SSA name for the skip edge: > > > <bb 38> [local count: 16140304]: > # prephitmp_78 = PHI <prephitmp_61(35), prephitmp_64(32)> > # c_I_lsm.18_79 = PHI <c_I_lsm.18_60(35), c_I_lsm.18_60(32)> > # iftmp.0_80 = PHI <iftmp.0_59(35), iftmp.0_66(32)> > FWIW I just fixed a similar bug in my early break rebasing branch. I can check if it fixes this one too.
