Please complete the implementation of the function given in the question section below.

Test your functions using the main program given. Please note main program may have missing lines or code. You are required to identify missing code and complete it.

QUESTION: Write a function to change variable from little endian to big endian notation in assembly.

The basic structure of the function is given in the attached assembly language file. You are expected to complete the function int toBigEndian(int variable) which converts an integer variable passed from little endian to big endian notation. The conversion function should simply accept the number variable and flip the order of the bytes and return the resulting value. For example

Variable passed to function 0xAABBCCDD?The value returned from the function 0xDDCCBBAA

Complete the function implementation which takes a little endian notation as input and returns the big endian notation of the given value from the function as given in the above example.

The function with the basic commands for the function entry and exit / return are already given. Use the given function and fill in your implementation where it is specified as below:

TO DO: Your implementation should be here

*/

Note: The function can be implemented using the following instructions:

ANDL?

ORL?

ADDL

SUBL

XORL

SHL

SHRL

THESE ARE THREE SEPERATE FILES THAT ARE INCLUDED IN THE PROGRAM!
