--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
So on targets where the FP constant loads are separate insns the load of the
negated constant could be replaced by a (neg:DF ..) which might even be
profitable when not combined with the following add.  As said targets like
x86 might be more difficult in this regard though it looks like the
memory operands in this case only appear during LRA.
