It is -flto (and if you are really keen, add -fwhopr with
-fwhole-program - experimental).
I would not advocate adding it by default. Linking is a lot slower
(obviously) and it seems to use more memory... sometimes a lot more.
I'd let the ricers play with this flag for a while before considering it
as the default.
