_mm_sha1rnds4_epu32

#define _mm_sha1rnds4_epu32	(		V1,
			V2,
			M
	)		__builtin_ia32_sha1rnds4((__v4si)(__m128i)(V1), (__v4si)(__m128i)(V2), (M))

Performs four iterations of the inner loop of the SHA-1 message digest algorithm using the starting SHA-1 state (A, B, C, D) from the 128-bit vector of [4 x i32] in V1 and the next four 32-bit elements of the message from the 128-bit vector of [4 x i32] in V2.

Note that the SHA-1 state variable E must have already been added to V2 (_mm_sha1nexte_epu32() can perform this step). Returns the updated SHA-1 state (A, B, C, D) as a 128-bit vector of [4 x i32].

The SHA-1 algorithm has an inner loop of 80 iterations, twenty each with a different combining function and rounding constant. This intrinsic performs four iterations using a combining function and rounding constant selected by M[1:0].

__m128i _mm_sha1rnds4_epu32(__m128i V1, __m128i V2, const int M);

This intrinsic corresponds to the SHA1RNDS4 instruction.

Parameters

V1	A 128-bit vector of [4 x i32] containing the initial SHA-1 state.
V2	A 128-bit vector of [4 x i32] containing the next four elements of the message, plus SHA-1 state variable E.
M	An immediate value where bits [1:0] select among four possible combining functions and rounding constants (not specified here).

Returns

A 128-bit vector of [4 x i32] containing the updated SHA-1 state.
