Write an x86-64 procedure/function called computepolynomial that does the following: it is passed six 2 byte parameters, coefx, coefy, coefz, x, y, and z by the procedure/function that calls it. computepolynomial returns a 4 byte value. a c-language prototype of the function is: short computepolynomial(short coefx, short x, short coefy, short y, short coefz, short z); note: insure that you are cognizant of what register has which value in it! it computes the value of (coefx * x5) - (coefy * y3) + (coefz * z), and returns the result in the appropriate register. be sure to do the proper stack set up work at the beginning and end of the procedure/function, and be sure to save and restore the values of any callee save registers that you modify. if arithmetic overflow occurs after any operation, return 0 to the calling function.
