Unformatted text preview: max(int x, int y) { return (x < y) ? y : x; } Homework Problem 5.13 [Category 2]: Using conditional moves, the general technique for translating a statement of the form: val = cond-expr ? then-expr : else-expr; is to generate code of the form: val = then-expr; temp = else-expr; test = cond-expr; if (test) val = temp; where the last line is implemented with a conditional move instruction. Using the example of Practice Problem 5.5 as a guide, state the general requirements for this translation to be valid. Homework Problem 5.14 [Category 2]: The following function computes the sum of the elements in a linked list: 1 2 3 4 5 6 7 8 static int list_sum(list_ptr ls) { int sum = 0; for (; ls; ls = ls->next) sum += ls->data; return sum; } The assembly code for the loop, and its translation of the ﬁrst iteration into operations yields the following: Assembly Instructions .L43: addl 4(%edx),%eax movl (%edx),%edx testl %edx,%edx jne .L43 Execution Unit Operations movl 4(%edx.0) addl t.1,%eax.0 load (%edx.0) testl %...
