This benchmark suite shows whether the compiler optimizes simple loops. If any of the benchmarks does not show linear cost, then the compiler optimizes it. This will probably impact other benchmarks as well.
| for loop | An empty for loop. |
| for loop result | A for loop that accumulates a result in a variable. |
| while loop | A while loop that counts in a variable without returning a result. |
| while loop result | A while loop that accumulates a result in a variable. |
| do while loop | A do-while loop that counts in a variable without returning a result. |
| do while loop result | A do-while loop that accumulates a result in a variable. |
