After all the Poll Request discussions (see

Thanks to all participants.
The RFC is open for discussion: https://wiki.php.net/rfc/jit-ir
Thank you. I find it important to follow the formal process, even if
many folks are not able to make a meaningful decision due to the lack of
knowledge about the topic. This includes me.
That said, I'd like to add my two cents to the "Open Issues" section:
My understanding is that even if the new JIT might not (yet) be better
than the old one, it is not worse and it is more maintainable. The
reactions from more knowledgeable folks were pretty positive overall.
So if the new JIT passes the existing test suite without issues, I don't
see a reason why the old JIT should not be replaced right away. By
immediately removing the old JIT (ideally in a separate commit) the
codebase is cleaned up and users that want to test PHP 8.4 (or whatever
that version may be in the end) will be forced to also test the new JIT
which is probably a good thing.
Best regards
Tim Düsterhus
