That works for me. If you haven't already committed the change, please make a quite note about the planned move to meson and reenablement of LTO at that point so I don't dig any further when I review all the opted-out packages. I'm likely to forget the decision by the time I'm reviewing the opt-outs. > > > libtool is really not built for LTO, and it really should not be used on > > GNU systems.

Yea, I find libtool amazingly painful and the primary motivation for it has long since become a minor issue rather than major one (seriously who cares about dynamic linking on hpux, sco, irix, etc) anymore. But killing it I'm sure will be difficult. jeff > _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
