I told you I just glanced at the code :) In that way, if you guys decide to merge this new algo, you'll need to split the prepare from the optimize, and feed it with an already prepared env. Before going that way, have you ever tried to tweak xdl_cleanup_records and xdl_clean_mmatch to reduce the level of optimization, and see the results you get? It is possible that you won't need two different algos inside git. - Davide -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
