Hi all,
This hunk that slightly reduces the cost of immediate moves doesn't actually
have any effect.
In the whole of SPEC2006 it didn't make a difference. In any case, I'd like to
move to a point
where we use COSTS_N_INSNS units for our costs and not increment decrement them
by one.
This patch removes that bit of logic and makes it slightly cleaner to look at.
As far as I know
its logic has never been confirmed in practice.
Bootstrapped and tested on arm.
Ok for trunk?
Thanks,
Kyrill
