Author: ngie Date: Tue Jun 27 06:02:50 2017 New Revision: 320396 URL: https://svnweb.freebsd.org/changeset/base/320396 Log: Stash work for adding runtime coverage support to bsd.lib.mk The initial work uses static libraries instead of dynamic libraries, for parity with pico-style libraries. I suspect this approach is slightly flawed, but I wanted to stash the WiP, just in case.
