BIT_ANDTC_EXPR - kill it?

In fold-const.c, I have found this:

    case BIT_ANDTC_EXPR:
      low = int1l & ~int2l, hi = int1h & ~int2h;
      break;

In ./gcc/cp/lex.c:
  operator_name_info [(int) BIT_ANDTC_EXPR].name = "&~";

As I expected, it seems to be X & ~Y.




What do you think about killing BIT_ANDTC_EXPR ?

There are only few uses of it, majority of them is in something like
this:
case BIT_AND_EXPR:
case BIT_ANDTC_EXPR:
case BIT_OR_EXPR:
  something;
  break;
