1.27.0[−][src]

    pub unsafe fn _mm_sha256rnds2_epu32(
        a: __m128i,

        k: __m128i

This is supported on x86-64 and target feature `sha` only.
Expand description

Performs 2 rounds of SHA256 operation using an initial SHA256 state (C,D,G,H) from `a`, an initial SHA256 state (A,B,E,F) from `b`, and a pre-computed sum of the next 2 round message values (unsigned 32-bit integers) and the corresponding round constants from `k`, and store the updated SHA256 state (A,B,E,F) in dst.
