(a) Show an example which illustrates that the coalescing of two copy-related live ranges can be beneficial (eliminates a register to register move). (b) Show a counter-example where coalescing can be harmful (causes a spill). Assume the number of registers is three. A live range is copy-related to another if it ends with a copy of its last use being the star of the next range’s definition (a = b where this is the start of a’s definition and b’s last use).
