--- Comment #6 from Martin Jambor <jamborm at gcc dot gnu.org> ---
It is the char[] part of the declaration that causes this, changing it
to a pointer also avoids the issue.

In GCC 11, functions with parameters which are these length-less
arrays automagically receive an access function type attribute and
IPA-SRA does not understand them and so punts.

Understanding some attributes, eventually including access, is on my
TODO list, meanwhile please use a pointer type.=
