------- Comment #9 from bergner at gcc dot gnu dot org 2008-04-11 19:08 -------
This isn't accessing data below the stack pointer, it's accessing below the
previous stack pointer value which is in the current stack frame.
>From a technical standpoint, the ppc64 ABI allows us to access some number of
bytes (144?) below the stack pointer, but the ppc32 ABI does not.
