That only fixes the -fpatchable-function-entry= case.
aarch64-bti-insert.cc needs to be fixed too:
/* Since a Branch Target Exception can only be triggered by an indirect call,
we exempt function that are only called directly. We also exempt
functions that are already protected by Return Address Signing (PACIASP/
PACIBSP). For all other cases insert a BTI C at the beginning of the
function. */
if (!cgraph_node::get (cfun->decl)->only_called_directly_p ())
