A first 32-bit operand ( ) is treated as a signed shift value that has a sign and a shift count value. A second operand ( ) is shifted by an amount according to the shift count value and in a direction according to the sign of the shift count. One instruction is provided that performs a right shift for a positive shift count and a left shift for a negative shift count, and another instruction is provided performs a left shift for a positive shift count and a right shift for a negative shift count. If the shift count value is greater than 31, then the shift is limited to 31.
