   This should most times be not an issue, but will be for example if receiving
an odd number of integer/float arguments, and an even number of the other
type, but running out of registers, and needing to put some arguments on
the stack.

   I will implement @subject, matching jit_prepare{,d,f} semantics, but maybe
I am missing something, so, commenting here :-)

Yes, this approach is okay.
