JITs do PGO all the time. It’s their bread and butter.

Nowadays they also save PGO across executions, so that they don't always start from zero.

The most modern ones that is (Java, .NET, Android).

I don’t know if V8 does between runs but it seems to share something between subprocesses. There is commentary in the Node Worker docs about turning it off/on.
