--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Are you sure -fcompare-debug does sth sensible with -flto? With
-fno-use-linker-plugin you are turning on -ffat-lto-objects and thus you end up
emitting anything in the first place but you are comparing the fat part of the
LTO objects.

so funcdef_no "swaps".
