Write code for an assembly language function named rot_left_right which does a rotating left or right shift of a given integer (provided in R5) by an amount given in R10, bits 4:0. Bit 5 of R10 should be 1 to rotate left, or 0 to rotate right. The result should be returned in R11. You are not allowed to use the rotation assembly language instructions: neither ROR nor RRX. For example, if you call your function with R5=0x12345678 and the rotate amount R10=4 in bits 4:0 and the value 1 in R10 bit 5, the result should be rotated left by 4 bits: R11=0x23456781. If the user provides a rotate value of 0, then the function should return the original integer unchanged. Call your function from your mainline code, providing various parameters and checking the result for correctness.
