Question Description
The atomic fetch-and-set x, y instruction unconditionally sets the memory location x to 1 and fetches the old value of x in y without allowing any intervening access to the memory location x. consider the following implementation of P and V functions on a binary semaphorevoid P (binary_semaphore *s) { unsigned y; unsigned *x = &(s->value); do { fetch-and-set x, y; } while (y);}void V (binary_semaphore *s) { S->value = 0;}Which one of the following is true?a)The implementation may not work if context switching is disabled in P.b)Instead of using fetch-and-set, a pair of normal load/store can be usedc)The implementation of V is wrongd)The code does not implement a binary semaphoreCorrect answer is option 'A'.
