This is incorrect:

      case Instruction::FCmp:
        switch (CE->getPredicate()) {
          case FCmpInst::FCMP_ORD: 
          case FCmpInst::FCMP_UEQ: 
          case FCmpInst::FCMP_OEQ: Out << " == "; break;
          case FCmpInst::FCMP_UNO: 
          case FCmpInst::FCMP_UNE: 
          case FCmpInst::FCMP_ONE: Out << " != "; break;
          case FCmpInst::FCMP_OLT:
          case FCmpInst::FCMP_ULT: Out << " < "; break;
          case FCmpInst::FCMP_OLE:
          case FCmpInst::FCMP_ULE: Out << " <= "; break;

          case FCmpInst::FCMP_OGE:
          case FCmpInst::FCMP_UGE: Out << " >= "; break;
          default: assert(0 && "Illegal FCmp predicate");
        }
