--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I'm not sure why this is considered a simplification, two insns vs. two, and on
the subtraction it isn't specific to just one target, but I think for most the
constant will need to be forced into register, the immediates the instructions
have is mostly for the second operand.
