H A DREADME.md33 `ZEND_VM` architecture allows specializing opcode handlers according to
42 opcode handlers and helpers. The typical opcode handler template looks like
52 `<OPCODE-NUMBER>` is a opcode number (0, 1, ...)
53 `<OPCODE>` is an opcode name (ZEN_NOP, ZEND_ADD, :)
59 same as in old `zend_execute.c`, but now it uses macros to access opcode
124 `zend_vm_opcodes.h` and `zend_vm_execute.h`. The first file is a list of opcode
129 different opcode threading model using `--with-vm-kind=CALL|SWITCH|GOTO`. You
130 can disable opcode specialization using `--without-specializer`. You can include
