--- Comment #4 from Tamar Christina <tnfchris at gcc dot gnu.org> ---
most of the changes seem to be scheduling and register renaming, so I guess one
should compile with scheduling off to reduce the noise a bit.
detinp_ does have a weird transformation where a cluster of csel go missing and
replaced with mov, but the function is too big for me to quickly tell if this
is the issue.
