That's why some of the passes were run multiple times. Although the
results are sorted in commit order I did 3 separate passes through the
code when I was gathering the numbers. However you are right to say they
are indicative rather than strict benchmarking conditions - I've just
re-run on 3 commits:

So while the first commit showed a nearly 10% variation over multiple
runs (cache effects?) I think the step between float_cmask and
return_nan is more real.
I wonder if it would be worth tweaking the fp-bench program to make the
numbers a bit more stable? For total execution time runs I use hyperfine
which does at least try and measure the deviation between runs and trend
to a stable number but these numbers are reported directly by the
fp-bench tool.

The effect looks very real:
