Not if the argument(s) fits into the specified registers. There's
where the ABI comes in.

In a nutshell, the AAPCS-VFP extends the AAPCS to include cases where
the arguments are floating point, either literals or small vectors,
when they fit in VFP registers. This is similar to the AAPCS extending
the base standard regarding standard registers.
