--- Comment #12 from David Edelsohn <dje at gcc dot gnu.org> ---
What do you mean by size of a stack slot?  AIX stack pointer alignment was
increased to quadword, to allow for Altivec.  It doesn't really refer to the
alignment of objects on the stack. I assume that those followed the type
alignment rules in the ABI.
