--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Can you provide the following:
* How you configured/built GCC?
* What command line options that you pass to GCC for building your application?

I am suspecting you are not using the correct options to get the  __aeabi_f2ulz
that does not convert to double first.
