- Subject: [PATCH, committed] reload.c latent bug fix
As with the earlier rtlanal.c latent bug, another case of nearly
identical code testing inner_regno, instead of regno, before accessing
hard_regno_nregs array using regno.
David
* reload.c (refers_to_regno_for_reload_p): Test regno, not inner_regno,
against FIRST_PSEUDO_REGISTER.
