When all of these options (equivalent_register_removal +
register_duplication + register_balancing) are enabled, they all work
fine and do what they are supposed to do ... but because i don't want
it to remove the equivalent registers, i disabled this option but now
because of disabling equivalen_register_removal both
register_duplication and register_balancing don't do anything anymore?
... are all of these features heavily related to each other????
thanks in advance for your reply,
