Hi Guys,
A quick question: is it possible to enable AVX2/AVX3 in PHP JIT generated code,
and hence can get some performance improvement?
Just check the community first: if anyone has already tried that or got some
experiences? before we dive into this investigation.
We are discussing if we coul

ZEND_JMP_SPEC_HANDLER(ZEND_OPCODE_HANDLER_ARGS)

Oh, probably this is just the biggest prime number that fits into a sign
Thanks Dmitry for the information.
With a few debug sessions, I found that 32531 is working well
