consteval simd< std::uint64_t, 2, Arch >	native::pmull (std::uint64_t a, std::uint64_t b) noexcept
	Evaluate a 64-bit polynomial product at compile time using an available SIMD storage shape.
template<isa< arm > Arch> requires (Arch.has(arm_feature::pmull))
constexpr simd< std::uint64_t, 2, Arch >	native::pmull2 (simd< std::uint64_t, 2, Arch > a, simd< std::uint64_t, 2, Arch > b) noexcept
	Multiply the high 64-bit polynomial lane of each operand; lower lanes are ignored.
template<isa< arm > Arch> requires (!Arch.has(arm_feature::pmull) && requires { sizeof(simd<std::uint64_t, 2, Arch>); })
consteval simd< std::uint64_t, 2, Arch >	native::pmull2 (simd< std::uint64_t, 2, Arch > a, simd< std::uint64_t, 2, Arch > b) noexcept
	Evaluate constant operands without the instruction feature.
