-; ARM's frame lowering attempts to tack another callee-saved register onto the
-; list when it detects a potential misaligned VFP store. However, if there are
-; none available it used to just vpush anyway and misreport the location of the
-; registers in unwind info. Since there are benefits to aligned stores, it's
-; better to correct the code than the .cfi_offset directive.
