--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
contrib/compare-debug strips off LTO sections but that would leave us with a
no-op compare.  On any target using non-native sections just stripping
.gnu.lto_.opts
will be difficult in such script, so we'd need to build a compare-lto tool
and use that.

But as said, comparing LTO bytecode is of questionable value and comparing the
binaries doesn't work...
