avx2指令存储8个整数是什么?
问题描述:
我想将8个整数从 __ m256i
变量存储到8 x 32位 int
s的数组中.我以为该指令是 _mm256_store_epi32
,但是我收到一条错误消息,指出该指令甚至不存在!
I want to store the 8 integers from a __m256i
variable to an array of 8 x 32 bit int
s. I thought the instruction for that would be _mm256_store_epi32
, but I get an error that this instruction doesn't even exist!
答
看看 _mm256_store_si256
或 _mm256_storeu_si256 .
Have a look at the Intel Intrinsics Guide. Depending on whether your destination is aligned, you need _mm256_store_si256
or _mm256_storeu_si256
.
