Hi Aldy, Hi Alex,
I am going to apply the patch below to fix an "obvious" problem with
the FRV port. Namely that the reg_or_0_operand predicate is
intended to work with CONST_DOUBLES (amongst other rtx types) but
its definition was not allowing them.
I think that this patch ought to be applied to the 4.2 and 4.1
branches as well, but I am not sure if it counts as a regression.
What do you think ?
Cheers
Nick

I'm OK with applying to the branches.
