+To be able to target standard processors, reverse if-conversion can be
+used to create if-statements and branches based on the predicated
+instructions. Scheduling over multiple blocks can then be performed by
+adding predicates, doing if-conversion ([\#1c8]) and hyperblock
+scheduling ([\#1b8]). Then, to convert back to a basic-block view of the
+code, reverse if-conversion can be used. This therefore has a similar
+effect to scheduling instructions using trace scheduling ([\#3c3f]).
