        <pre>I run opt with the attached IR, bugpoint-reduced-simplified.ll, and the flags
-basicaa -sroa -S outputting the IR to a file, output1.ll.

I then use the output1.ll as input to opt again with the same flags (-basicaa
-sroa -S) and redirect the output to output2.ll.

The only difference is the value names:
$ diff output1.ll output2.ll
1c1
