Doesn't the issue go further than that? The PCS says (5.5): "A variadic function is always marshaled as for the base standard." Which seems to mean the correct change is basically replacing any check for "AAPCS_VFP" with "AAPCS_VFP && !isVariadic" (with any simplifications that might be possible). Cheers.
