; These functions perform extra work to ensure that `%a3` starts in a
; floating-point register, if the machine has them, and the result of
; the bitwise operation is then needed in a floating-point register.
; This should mean the optimisations will fire even if you're using the
; soft-float ABI on a machine with hardware floating-point support.
