Is there some more glue in sys/conf we can axe as well? Specifically, all the places that check PROFLEVEL?

kib updated this revision to Diff 86708.Apr 1 2021, 8:11 PM

Remove PROF/PROVLEVEL etc from sys/conf Makefile's pieces.

FWIW ....
I read gcov, but sys/gnu/gcov survived. Perhaps it was meant to be gprof?

gnu/gcov is for line coverage not for sampled profiling. I have no idea about its state, and does it work with any modern gcc.
