* | Speed up fetching of class entries for self:: parent:: and static::Dmitry Stogov2015-10-281-2/+11
|/ | | | | | | | | | | | | | | | | | | | | | This is generalized solution for Bob's idea of speed up self::method() calls without ZEND_FETCH_CLASS. At first, it adds few new opcodes to separate class related behaviour: FETCH_STATIC_PROP_R FETCH_STATIC_PROP_W FETCH_STATIC_PROP_RW FETCH_STATIC_PROP_FUNC_ARG FETCH_STATIC_PROP_UNSET FETCH_STATIC_PROP_IS UNSET_STATIC_PROP ISSET_ISEMPTY_STATIC_PROP FETCH_CLASS_CONSTANT At seconds, it enables IS_UNUSED operand to fetch (self, parent or static without separate FETCH_CLASS) for new opcodes and the following ones: INIT_STATIC_METHOD_CALL NEW END_INSTANCEOF Finaly, opcache optimizer had to be fixed to support new opcodes.

| | | | | | | | | | | | | | | | | | | | | | In PHP-5.6 and below each argument passed to user function was copies on VM stack twice. Now we always have ZEND_INIT_FCALL (or simular) opcode that pushes "call frame" on top of VM stack. "Call frame" is actually the same zend_execute_data structure. All the following ZEND_SEND instructions push arguments on top of the stack in a way that they directly comes into corresponding CV variables of the called frame. Extra arguments are copied at the end of stack frame (after all CV and TMP variables) on function enterance. There are two minor incompatibilities: 1) It's not allowed to decalre functions redefining arguments e.g. "function foo($a,$a) {}". 2) func_get_arg() and func_get args() return the current value of argument and not the original value that was sent.
