Add a clause that maps result1 and result2 offsets to a common base and then compares that result. This fixes some noisy diffs from instrumented Tier0 compiles, where the probe addresses can vary from run to run.

@BruceForstall PTAL Would be nice to run this on some "known" diff cases to make sure it's not suppressing true diffs. Any ideas? |
You could induce diffs by, e.g., turning off a phase for one JIT. But you'll have to figure out how to induce just the right kind of diff for this to hit or not hit. |
