inline constexpr int max_fixed_size = /*implementation-defined*/;
(parallelism TS v2)

The value of max_fixed_size<T> declares that an instance of simd<T, fixed_size<N>> with N <= max_fixed_size<T> is supported by the implementation.

[edit] Notes

It is unspecified whether an implementation supports simd<T, fixed_size<N>> with N > max_fixed_size<T>. The value of max_fixed_size<T> may depend on compiler flags and may change between different compiler versions.
