Hi,
After the code-review feedback, one of the most questionable decisions was
changed.
Instead of including IR Framework as a git submodule, now its part is
embedded into php-src.
This will complicate the IR/JIT development a bit, but will simplify things
for everyone else.
I'm going to merge https://github.com/php/php-src/pull/12079 into master
next week.
If someone likes to take a look before, please do it now.
After the merge, I don't plan to do active PHP-JIT development for 1-2
months (I'll wait for problems, bugs, etc and work on general IR
improvements).
Then, in case of no major problems, I'm going to remove the old JIT
implementation and make a PHP-JIT code-cleanup pass.
Thanks. Dmitry.

Hi internals,
I'm glad to present a new JIT engine that is going to be used in the next
major PHP version. Now it's a real optimizing compiler with Intermediate
Representation similar to Java HotSpot server compiler.
It makes a base for future improvements and eliminates many low-level
details of the existing PHP JIT. Instead of supporting assembler code for
different CPUs, now PHP generates a single IR and passes it to a
PHP-independent JIT engine.
The old JIT implementation is going to be kept for a while.
Everybody are welcome to take a look over tne code
https://github.com/php/php-src/pull/12079
Thanks. Dmitry.
If merged to `master`, will that automatically mean that the next
version of PHP will be PHP 9.0 ?
If so, would that warrant a separate discussion ? (whether there should
still be a 8.4/8.5/8.6 or not)
Smile,
Juliette
