__fp16 isn't ambiguous, calling std::exp with an argument of that type
is ambiguous, because the standard library doesn't provide an overload
for that type.
It could be added (probably defined to cast to float and use the

No, there isn't a solution for this. You might want to try an ARM port
clang/gcc to

__fp16 foo (__fp16 a, __fp16 b)
{
return a + std::exp(b);
}
