--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
There isn't really any advantage of either form, both are the same number of
instructions, and after all, for higher shift counts the shift is more
efficient (we have a combine splitter for that already).
So, the only reason for the transformation would be code canonicalization.
