I've seen this optimization mentioned a few places, but nobody seems to
agree on the name.


So, I thought I'd ask and see if someone else seen a definitive name for it.


        if (x == 1 && y == 2)
                z = 300 / (x + y)


==>


        if (x == 1 && y == 2)
                z = 100




Can anyone help me name that optimization?


Thanks,
Chris
