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

I looked into the sources of libgcc, __aeabi_f2ulz is defined as __fixunssfdi
which is defined in soft-fp/fixunssfdi.c and that does:
```
UDItype
__fixunssfdi (SFtype a)
{
FP_DECL_EX;
FP_DECL_S (A);

Let me ask a dumb question, are you porting GCC/gccgo to a libc which does not
have ucontext.h ? If so what is the libc my I ask?

If you remove the class, GCC has a decent error message:

This shouldn't have vectorized as outer-loop vectorization isn't supported. In
