3a794d39f0 Avoid repeatable ARG_SHOULD_BE_SENT_BY_REF() checks in FETCH_*FUNC_ARG and following SEND_VAR_EX. Perform the check once in a new CHECK_FUNC_ARG opcode and reuse in the following FETCH_*FUNC_ARG and SEND_FUNC_ARG (SEND_VAR_EX replacement). 2018-02-05 19:40:06 +03:00

5f4f83220a Don't inline if function has ref arguments 
Otherwise we end up leaving opcodes like FETCH_DIM_W behind. The
test case demonstrates a leak in particular.

64dae1ea76 Statically bind static method call arguments 
If we know what method will be called, use ct-bound send opcodes.

The intl test is changed because a runtime error changed to a
compile-time error.

eb7be5379d Speed up fetching of class entries for self:: parent:: and static:: 
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.

c2c78dc963 Added specialized versions of DO_FCALL handler: 
DO_ICALL - for internal functions
  DO_UCALL - for user functions
  DO_FCALL_BY_NAME - plain, most probably user, funcstions (not methods)

de306e7088 Implement call_user_func() and call_user_func_array() using special opcodes. 
In some rare cases it leads to insignificant changes in error messages.

b7715c7e8a Refactored parameter passing mechanism. 
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.
