-Use @option{-fsched2-use-superblocks} algorithm when scheduling after register
-allocation and additionally perform code duplication in order to increase the
-size of superblocks using tracer pass. See @option{-ftracer} for details on
-trace formation.

-This mode should produce faster but significantly longer programs. Also
-without @option{-fbranch-probabilities} the traces constructed may not
-match the reality and hurt the performance. This only makes
-sense when scheduling after register allocation, i.e.@: with
-@option{-fschedule-insns2} or at @option{-O2} or higher.
