I don't really think it's important. The main consideration is the toolchain. We use illumos as an upstream, which is pretty inactive at this point. Joyent's illumos fork has put a lot of work into the CTF toolchain, and OpenBSD has made some progress towards an ISC-licensed ctfconvert utility. I'd like to import the latter, since the permissive license means that we can use it in DDB. It requires more work because of some missing functionality, though. At some point I think we'd like to pursue one of these two upstreams, so it becomes a question of whether they're amenable to modifying the CTF binary format (and there are some other limitations that ought to be fixed in the process), and if not, whether it's painful to maintain the local modifications needed to support large enums. _______________________________________________ svn-src-head@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
