--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I guess the question is, do we guarantee the standard stack alignment for the
_mcount call or not? In any case, this call is very special, has different
calling conventions than other functions, and sometimes (e.g. for fentry) is
performed before the prologue, so even less likely to have aligned stack.
So, do we want any stack guarantees for mcount and/or fentry on Linux?
Similarly other OSes. Aligning stack in the callers can be of course done, but
isn't without code size and performance implications.
