SciMark 2.0 has lots of tight loops that are ideal for perf. Just stating the
benchmark score of two compilers does not represent a good report. We need at
least a perf report, with eventual analysis of hot spots. Something similar to
[1] is a good start.
For regressions, a regression hunt like [2] is also welcome
