A spot of CVS archeology revealed that it was removed as
a primop as part of a NCG overhaul couple of months ago.
Don't know if leaving it out was simply an omission or
if there's something deeper going on.
Anyway, you can approximate
unsafePtrEq :: a - a - Bool
unsafePtrEq a b = (unsafeCoerce# a) `eqAddr#` (unsafeCoerce# b)
which is fine by me.

Did unsafePtrEq disappear between 5.02
and 5.03? - Conal
GHC.Base
unsafePtrEq :: a - a - Bool
unsafePtrEq a b = (unsafeCoerce# a) `eqAddr#` (unsafeCoerce# b)
Clearly, it doesn't chase indirections.
