Loop unswitching. This pass moves the conditional jumps that are invariant
out of the loops. To achieve this, a duplicate of the loop is created for
each possible outcome of conditional jump(s). The pass is implemented in
@file{tree-ssa-loop-unswitch.c}. This pass should eventually replace the
RTL level loop unswitching in @file{loop-unswitch.c}, but currently
the RTL level pass is not completely redundant yet due to deficiencies
in tree level alias analysis.
