            Bug ID: 68898
           Summary: ICE if rtl if-conversion is off.
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: rtl-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ysrumyan at gmail dot com
  Target Milestone: ---

I tried to play with if-conversion flag and got ICE on all benchspec2 from
spec2000 suite. I attach simple Fortran reproducer. Note that
"-fno-if-conversion2" option does not lead to CF.
