I do not understand the intention of this patch for rs6000. Is
the new hook only implemented for supported vector types? ALIGN_POWER is
not natural alignment for 64-bit double, so I do not understand why the
hook returns true for MASK_ALIGN_POWER under TARGET_MACHO and does not
include a test for AIX.
Thanks, David
