--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
That is true, but whether it is lea or add is decided only during split after
reload, and the optimization where the cmov could use directly the result of
earlier comparison rather than forcing it into a GPR is usually done during
combine where it can't be done because of that.
