[Solved] How do I optimize C code using loop transformation? [closed]

by


Aside from using two separate loops, the original code contains lots of redundant statements. One possible improvement would be this:

int tmp = 6 * h;
for (j = 1; j <= 4; j++) {
     a[j] = tmp;
     b[j] = 6 + 3 * j * j;
}

The main optimizations:

  • One loop instead on two
  • Removed assignments that get overwritten in the next statement
  • Calculate a value that does not depend on the loop index outside the loop

You should be aware that most of these optimizations would be done by a compiler anyways.
