Hello,
I've been looking at the following code trying to understand what it does:
/* simulate getf.sig/setf.sig */
if (write) {
if (*nat) {
/* write NaTVal and be done with it */
addr[0] = 0;
addr[1] = 0x1fffe;
return 0;
}
addr[1] = 0x1003e;
} else {
if (addr[0] = 0 && addr[1] = 0x1ffe) {
/* return NaT and be done with it */
*val = 0;
*nat = 1;
return 0;
}
}
In particular, I'm puzzled about the "0x1ffe" constant for the read case.
Shouldn't that be 0x1fffe (with one more 'f'), i.e. the binary representation
of NaTVal?
