As far as I can tell most/all developers have used sampling-based profiling for years (e.g. hwpmc on FreeBSD) and have not been using gprof-based profiling. Prompted by followup to a pkgbase tweak I committed relating to profiling libraries[1] I propose following Brooks' suggestion: * turn off the PROFILE option by default now, in advance of the FreeBSD 13 branch (WITH_PROFILE will remain available) * update the WITH_PROFILE description in src.conf(5) to mention that it's deprecated * remove support for WITH_PROFILE after FreeBSD 13 branches Any comments on this plan? Does anyone use the -pg compiler flag and the _p.a profiling library archives? [1] https://lists.freebsd.org/pipermail/svn-src-all/2020-January/192566.html
