--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So the difference between with/without +fp16 is -fexcess-precision=16 vs
without that option.
On x86_64 with -fexcess-precision=16, we get the same link failure.
Maybe Jakub understands what is the correct behavior here; (since he added
bfloat16 support to x86_64; r13-3292-gc2565a31c1622ab0926aeef4a6579413e121b9f9
).
