--- Comment #10 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
If we are emitting for nested functions
pushq %r10
1: call __fentry__
popq %r10
(is it ok to misalign the stack for __fentry__? but then even plain call
__fentry__ actually misaligns it), then perhaps we can do similarly for the PIC
case. But I wonder how does __fentry__ then find the caller if it can't rely
on the return address being right above the return address to the function that
called __fentry__ (appart from unwind info of course, but we don't really emit
.cfi_* directives here either, do we?).
