Rotate right the following bit pattern by two bit positions:
The rotate instructions are both pseudoinstructions. Each one takes four basic instructions to implement. The shift amount is given in a register or as an immediate operand.
rol d,s,t # d <—s rotated left by t # (pseudoinstruction)
ror d,s,t # d <— s rotated right by t # (pseudoinstruction)
Negative immediate operands are not allowed. However, if the third operand is a register it may contain a negative integer. In that case the rotation is the opposite direction.
Inspect the following:
li $t2,-2 li $t1,4 ror $t0,$t1,$t2
$t0 hold after the sequence has executed?
