Changes are done in the Loop Invariant(LICM) at RTL level and also the
Induction variable optimization based on SSA representation. The current
logic used in LICM for register used inside the loops is changed. The

in the register used inside loop for
LICM and IVOPTS.
Changes are done in the Loop Invariant(LICM) at RTL level and also the
Induction variable optimization
based on SSA representation. The current logic used in LICM for register used
inside the loops is changed.
