LTO can be used without LTOing gcc itself. It is normally built by
default if the target supports it.

I believe it's very similar

I suspect this will break regularly too
(I personally did numerous changes to perf script output, and also

It's usually rather simple to fix up autofdo for new perf.
I did it before here
