--- Comment #23 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Note, given that in PR90329 a workaround has been introduced for such buggy
cases (that time to disallow functions with the DECL_HIDDEN_STRING_LENGTH
arguments from making certain tail-calls and call them normally instead), if
the PowerPC backend maintainers wanted, there could be a similar workaround on
the rs6000 backend side,
in the decisions whether the callee can use the parameter save area or not
ignore counting DECL_HIDDEN_STRING_LENGTH PARM_DECLs, so if e.g. 9 arguments
are passed but one of them is DECL_HIDDEN_STRING_LENGTH, assume parameter save
area is not there.
