Function core::arch::x86::_mm512_clmulepi64_epi128 [−][src]
pub unsafe fn _mm512_clmulepi64_epi128<const IMM8: i32>(
a: __m512i,
b: __m512i
) -> __m512i
This is supported on x86 and target feature
avx512vpclmulqdq,avx512f only.Expand description
Performs a carry-less multiplication of two 64-bit polynomials over the finite field GF(2^k) - in each of the 4 128-bit lanes.
The immediate byte is used for determining which halves of each lane a and b
should be used. Immediate bits other than 0 and 4 are ignored.
All lanes share immediate byte.
