andi Wed Sep 8 18:14:13 2004 EDT Added files: /ZendEngine2 zend_vm.h zend_vm_handlers.h zend_vm_spec.h Modified files: /ZendEngine2 zend_compile.h zend_exceptions.c zend_execute.c zend_execute.h zend_execute_API.c zend_opcode.c Log: - Some architectural changes: a) We specialize opcodes according to op_type fields. Each opcode has to be marked with which op_type's it uses. b) We support different execution methods. Function handlers, switch() and goto dispatching. goto seems to be the fastest but it really depends on the compiler and how well it optimizes. I suggest playing around with optimization flags. - Warning: Things might break so keep us posted on how things are going. (Dmitry, Andi)
