Functions
template<isa< x86 > Arch> requires (Arch.has(x86_feature::sm3) && Arch.has(x86_feature::avx))
constexpr simd< std::uint32_t, 4, Arch >	native::sm3msg1 (simd< std::uint32_t, 4, Arch > a, simd< std::uint32_t, 4, Arch > b, simd< std::uint32_t, 4, Arch > c) noexcept
	First SM3 schedule step.
template<isa< x86 > Arch> requires (Arch.has(x86_feature::sm3) && Arch.has(x86_feature::avx))
constexpr simd< std::uint32_t, 4, Arch >	native::sm3msg2 (simd< std::uint32_t, 4, Arch > a, simd< std::uint32_t, 4, Arch > b, simd< std::uint32_t, 4, Arch > c) noexcept
	Final SM3 schedule step.
template<isa< x86 > Arch, unsigned Imm8> requires (Arch.has(x86_feature::sm3) && Arch.has(x86_feature::avx) && Imm8 <= 255)
constexpr simd< std::uint32_t, 4, Arch >	native::sm3rnds2 (simd< std::uint32_t, 4, Arch > a, simd< std::uint32_t, 4, Arch > b, simd< std::uint32_t, 4, Arch > c) noexcept
	Two SM3 rounds; Imm8 is masked with 0x3e. a holds unrotated CDGH and b holds ABEF.

Detailed Description

Runtime calls require AVX and SM3, matching compiler targets and OS vector state. Constant evaluation preserves the instruction lane packing and modulo-word arithmetic. Missing-feature overloads are constant-evaluation-only.
