commit e1d559f337de2c8ab68a6749dfe873477c883807
Author: Florian Weimer <fweimer@redhat.com>
Date: Sat Nov 2 20:04:02 2019 +0100
Introduce link_map_audit_state accessor function
To improve GCC 10 compatibility, it is necessary to remove the l_audit
zero-length array from the end of struct link_map. In preparation of
that, this commit introduces an accessor function for the audit state,
so that it is possible to change the representation of the audit state
without adjusting the code that accesses it.
Tested on x86_64-linux-gnu. Built on i686-gnu.
