Function serde::lib::core::arch::x86_64::_mm_sha1rnds4_epu32

pub unsafe fn _mm_sha1rnds4_epu32<const FUNC: i32>(
    a: __m128i,
    b: __m128i,
) -> __m128i

Available on x86-64 only.

Performs four rounds of SHA1 operation using an initial SHA1 state (A,B,C,D) from a and some pre-computed sum of the next 4 round message values (unsigned 32-bit integers), and state variable E from b, and return the updated SHA1 state (A,B,C,D). FUNC contains the logic functions and round constants.
