I've never seen any warning about adding a backend pass in the plugin documentation, which may also register passes thanks to register_pass. I'm not a guru, but i think it's ok to add it as any other pass (might need confirmation). > The pass is added, but it's the last pass of all tree > passes, i.e. it's inserted after .optimized and > .statistics; at least the pass number indicate that. As for as I know, the static pass number is irrelevant in your case as it's only useful for debugging purpose. This number will be used in the tree-dump filename (if you ask for a particular dump), that's why *prefixed passes (that can't be dumped) use -1 as static pass number. So i'll advice you to check where your pass really is inserted otherwise (maybe with dump_passes()) Romain Geissler
