_mm256_sm4key4_epi32

#define _mm256_sm4key4_epi32	(		A,
			B
	)		(__m256i) __builtin_ia32_vsm4key4256((__v8su)A, (__v8su)B)

This intrinsic performs four rounds of SM4 key expansion.

The intrinsic operates on independent 128-bit lanes. The calculated results are stored in dst.

__m256i _mm256_sm4key4_epi32(__m256i __A, __m256i __B)

This intrinsic corresponds to the VSM4KEY4 instruction.

Parameters

__A	A 256-bit vector of [8 x int].
__B	A 256-bit vector of [8 x int].

Returns

A 256-bit vector of [8 x int].
