我想使用内在函数比较两个浮点变量.如果比较为真,就做点别的做点什么.我想将其作为正常的 if..else 条件来执行.有没有办法使用内在函数?
I want to compare two floating point variables using intrinsics. If the comparison is true, do something else do something. I want to do this as a normal if..else condition. Is there any way using intrinsics?
//normal code
vector<float> v1, v2;
for(int i = 0; i < v1.size(); ++i)
if(v1[i]<v2[i])
{
//do something
}
else
{
//do something
)
如何使用 SSE2 或 AVX 执行此操作?

我找到了一个对条件 SIMD 指令非常有用的文档.这是我问题的完美解决方案.如果...其他条件
I found a document which is very useful for conditional SIMD instructions. It is a perfect solution to my question. If...else condition
