Please help with this Assembly Language problem:

Consider the code fragment below: sell $t0, $t0, 1 sera $t0, $t0, 1 The above code fragment supposes to clear the MSB of $t0 to 0. Is there anything wrong with the above code fragment? Not only the MSB bit will be changed to 0, bit 30 will be changed too. LSB of $t0 will be changed to 0. Nothing wrong with the above code. If bit 30 is of $t0 is 1, after sell, sera will shift in 1 which makes the MSB of $t0 to be 1
