Author: dim Date: Tue Aug 25 20:07:11 2020 New Revision: 364784 URL: https://svnweb.freebsd.org/changeset/base/364784 Log: After r364423, which ensures the callbacks that dl_iterate_phdr(3) performs are protected by an exclusive lock, even for statically linked programs, it is safe to re-enable libunwind's FrameHeaderCache, which I temporarily disabled in r364263. Meanwhile upstream has also used the _LIBUNWIND_USE_FRAME_HEADER_CACHE for this purpose, so the only thing needed is to add this as a compile-time command line flag. While here, reformat the CFLAGS lines a little bit.
