a) Write the appropriate save instruction to allocate stack space for the following local variable declara- tion. short a[6]; save _________ , ______________________________ , _________ (Use the formula, not an absolute value) b) Write the appropriate instructions to perform the following assignment statements. a[5] = a[3];
a[2] = a[1];
short ptr; / ptr mapped to %l1 */ ptr = &a[0];
ptr++; /* ptr mapped to %l1 */
i = ptr; / i mapped to %l0; ptr to %l1 */
ptr = i; / i mapped to %l0; ptr to %l1 */
