--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The code is different though.  C has that
    case EQ_EXPR:
    case NE_EXPR:
    case LE_EXPR:
    case GE_EXPR:
    case LT_EXPR:
    case GT_EXPR:
      /* Excess precision for implicit conversions of integers to
         floating point in C11 and later.  */
      may_need_excess_precision =3D (flag_isoc11
                                   && (ANY_INTEGRAL_TYPE_P (type0)
                                       || ANY_INTEGRAL_TYPE_P (type1)));
      break;
part in which is from PR82071 and I can't find in the C++ standard a similar
change to what has changed from C99 to C11.
If you mean to share just
    case PLUS_EXPR:
    case MINUS_EXPR:
    case MULT_EXPR:
    case TRUNC_DIV_EXPR:
    case CEIL_DIV_EXPR:
    case FLOOR_DIV_EXPR:
    case ROUND_DIV_EXPR:
    case EXACT_DIV_EXPR:
then that sounds something not worth sharing to me.=
