It's not that HFAs are particularly special in variadic functions, but that AAPCS_VFP rules simply don't apply to variadics. HFAs don't exist as a concept, just like they don't for APCS or AAPCS. I think you get away with it because passing them as an HFA would be (e.g. "double, double, double") works with the backend anyway, but they should go as any other struct ([3 x i64] by the looks of it in that case).
