What's the latest CPU officially supported for older Windows version?

Hello.
So you all have heard that MS stop support Post-Skylake CPUs on Pre-Windows 10 OSes, my question is, how does the similar things happen on other Windows versions? For example, if I run Windows XP 64-bit on a Ivy-bridge CPU, will I experience any issue? Does that "officially" supported?
Thanks.

The biggest problems are the driver support. Look at a motherboard manufacturer's support page. Do they list Windows XP as a download option? That will give you the best insight.

This is the first time we've actually had an architecture "limit" on an Operating System. Windows XP technically should be able to run on the latest CPUs, however I'm sure XP would freak out.

I'd say the latest architecture to support an old OS is when the architecture just above it no longer receives drivers for that operating system.

Thank you all!
Sorry I can only pick one solution.
