--- Comment #2 from Martin Liška <marxin at gcc dot gnu.org> ---
Just for completeness, there's a list of profiledbootstrap warnings seen on
x86_64-linux-gnu (w/o -Wimplicit-fallthrough):

As I talked to Jakub, we used to have working profiledbootstrap w/o
--disable-werror. I can spend some time fixing these issues after stage1
finishes.
