| ; This verifies that the order of extract element instructions is |
| ; deterministic. In the past we could end up with different results depending |
| ; on the compiler used (due to argument evaluation order being undefined in |
| ; C++). The order of the extracts is not really important for correctness of |
| ; the result, but when debugging and creating test cases it is helpful if we |
| ; get the same out put regardless of which compiler we use when building the |
| ; compiler. |
