--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
I wonder if optimizing for "unused" parameters is worth it (usually IPA SRA
will elide them).  "unused" could be computed by cfgexpand walking the body,
but
we do expect to be able to inspect those parameters with -g, so care has to
be taken that this works at all optimization levels.
