I have a question. Does the stack need to be aligned on 16 bytes for access, or is it just the stupid fastcall64 convention that needs that?

In other words, will a custom asm convention need that? (why would it???)
just thought I'd ask (since I'm not programming x64 yet).

MOVDQA in APIs is one of the culprits, saving and loading XMMX registers to and from the stack.

MOVDQA MOVDQU LDDQU was a silly MOVe (pun intended)
