HW $1$

Problem $0(25$ points$)$

Write an assembly program that calculates the value of the following given polynomial, assuming signed

integers $x$ is stored in register $r0.($Note: $y$ can be $64-$bit$)$

$y=x^2+2x-8$

Problem $1(25$ points$)$

Write an assembly program to swap a register's upper and lower half words.
