Hi,
I propose a new VM instruction dispatch technique, that provides great speed up on small benchmarks
(1.5 times on bench.php)
Please review https://github.com/php/php-src/pull/2507
Take into account, that HYBRID VM is not enabled by default and VM has to be regenerated by
"php zend_vm_gen.php --with-vm-kind=HYBRID"
It doesn't work with phpdbg, out of the box, and may make some troubles to xdebug and other
system extensions.
I'm going to commit this into master after review and then rise question about enabling it by
default in PHP-7.2.
Thanks. Dmitry.
