A computer which issues instructions in order, has only 2 registers and 3 opcodes ADD, SUB and MOV. Consider 2 different implementations of the following basic block: Case 1   Case 2 t1 = a + b;    t2 = c + d; t2 = c + d;    t3 = e – t2; t3 = e – t2;    t1 = a + b; t4 = t1 – t2;    t4 = t1 – t2;   Assume that all operands are initially in memory.
