--- 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 = (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.
