1. [30pts] Suppose that $0 and $sl hold the values Ox40000000 and OxD0000000, respectively. a. [10pts] what is the value of $to for the following code? Is the value the desired result, or has there been overflow? add $t0, $50, $s1 b. [10pts] Using the same values in $s 0 and $sl, what is the value of $t0 for the following code? Is the value in $t0 the desired result, or has there been overflow? sub $t0, $50, $s1 [10pts] Using the same values in $s0 and $81, what is the value of $to for the following code? Is the value in $to the desired result, or has there been overflow? add $t0, $50, $s1 add $t0, $t0, $50
