Aligning a memory for SSE (AVX)

I’m curious which way is general way to aligning a memory for the SSE(AVX) and intrinsic in C++

I usually using just simple alignas() but I’m hesitating to using in this way.

Therefore I’d like to know which way is general or best to align memory for UE4?

Thank you!

What exactly are you trying to align? Loads? Allocated memory?
