--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
For -fsplit-stack you are right, __morestack seems to have hidden visibility,
so even if gcc emits call __morestack@plt, the linker should transform that
into
a direct call __morestack which doesn't need %ebx set up.
Profiling -fpic code would still remain broken though.
