There were others, but starting with these seems as good as any.
Sorry for that. Seems I managed to leave this one out of the final
patch. It is very sensitive to how things are inlined. If it breaks
again I guess I will try to work out explicit noinline/always_inline
attributes to make it to work.
If you want to cheat and consider it as a test only for FRE / DCE,
__attribute__((flatten)) on f should work. But it can be useful to keep it
in a state where it still tests the inliner as well...
