--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The loop does:
for (regno = aarch64_next_callee_save (start, limit);
regno <= limit;
regno = aarch64_next_callee_save (regno + 1, limit))
Really this:
bool reg_is_wrapped_separately[LAST_SAVED_REGNUM];
Should be:
bool reg_is_wrapped_separately[LAST_SAVED_REGNUM + 1];
In aarch64.h. It has been wrong since r7-5127 .
