Also here :
static void asm_expr_logic(TCCState *s1, ExprValue *pe)
{
int op;
ExprValue e2;
asm_expr_prod(s1, pe);
for(;;) {
op = tok;
if (op != '&' && op != '|' && op != '^')
break;
next();
asm_expr_prod(s1, &e2);
if (pe->sym || e2.sym)
tcc_error("invalid operation with label");
switch(op) {
case '&':
pe->v &= e2.v;
break;
case '|':
pe->v |= e2.v;
break;
default:
case '^': ///////////////////////////////////////what this case
after default mean ????????
pe->v ^= e2.v;
break;
}
}
}
