Re: coccinelle: merge two rules from flex_alloc.cocci

quoted

Does any test infrastructure (or benchmarks) exist which you would trust for
corresponding comparisons of software run time characteristics?

Yes, just run:

  make cocciclean
  time make contrib/coccinelle/flex_alloc.cocci.patch

Thanks for this suggestion.

before and after your changes, and include the timing results in the
commit message if there is a notable difference.

The measurements from my test system might not be representative enough.

FWIW, I did just that with your "coccinelle: merge twelve rules from
object_id.cocci" patch [1], and the runtime went down from 2m48.610 to
2m34.395, a bit over 8% speedup. (with Ubuntu 16.04's Coccinelle
1.0.4)

These numbers seem to be nice.
Would a direct reply have been more helpful for the referenced patch
than the current subject?
