_mm256_cvtepi32

Packed moves with sign-extend 32-bit signed integers to 64-bit integers. The corresponding Intel® AVX2 instruction is VPMOVSXDQ.

Syntax

extern __m256i _mm256_cvtepi32_epi64(__m128i s1);

Arguments

`s1`	128-bit integer source vector used for the operation

Description

Performs a packed move with sign-extend operation to convert 32-bit [doubleword] integers in the low bytes of the source vector, s1, to 64-bit [quadword] integers and stored as packed signed quadword integers in the destination vector.

Returns

Result of the sign-extend operation.
