Question

Chapter 5.1, Problem 5.1PP

Program Plan Intro

Given C code:

void swap(long xp, long yp)

{

xp = xp + yp;

yp = xp - yp;

xp = xp - *yp;

}

Memory aliasing:

It denotes a case where two pointers might designate to memory location that is same.

The compiler should assume that unlike pointers might be aliased for safe optimizations.

The program aspects that could limit chances for a compiler in generating optimized code denote optimization blockers.

If a compiler is unable to determine whether two pointers might be aliased, it should adopt that either case would be possible.

The possible optimization set is been limited in this case.
