Eliminated checks for (func->op_array.fn_flags & ZEND_ACC_GENERATOR) in fast path of DO_FCALL* handlers. This slightly improves calls to regular function and method calls in cost of a bit slower generator initialization. Separate call frame for generators, allocated on heap, now created by ZEND_GENERATOR_CREATE instruction.

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.

add T_POW (**) operator Fixed recognition of the operator Added opcode, still doing multiply instead of pow() opcode now always returns int(42) The right answer, but always a float Yanked code from pow() implementation.

Added pow() as a language construct. Adjusted test cases for changed precedence. Reduced pow() to shell function around ZEND_API pow_function() Reduced test case to only contain edge cases Added overloading test case Moved unary minus above T_POW Revert "Added pow() as a language construct." Bad bad bad idea. This reverts commit f60b98cf7a8371233d800a6faa286ddba4432d02. Reverted unary minus behaviour due to previous revert.

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.

Introduce BIND_LEXICAL This opcodes inserts a local CV into the closure static variable table. This replaces the previous mechanism of having static variables marked as LEXICAL, which perform a symtable lookup during copying.

Avoid live range references in opcodes Don't store the live range of the freed variable for FREE_ON_RETURN frees, instead look it up at runtime. As this is an extremely unlikely codepath (in particular, it requires a loop variable with a throwing destructor), saving the runtime lookup of the live range is not worth the extra complexity this adds everywhere else.

Avoid live range references in opcodes Don't store the live range of the freed variable for FREE_ON_RETURN frees, instead look it up at runtime. As this is an extremely unlikely codepath (in particular, it requires a loop variable with a throwing destructor), saving the runtime lookup of the live range is not worth the extra complexity this adds everywhere else.

Remove uses of VARs in extended_value The DECLARE_(ANON_)INHERITED_CLASS(_DELAYED) opcodes were referencing the parent ce VAR through extended_value. This is hacky and we can't track the def-use chain in SSA. To avoid this, the layout of declaration opcodes is changed as follows: op1 points to the lcname and rtd_key literals, in that order. (For anon/lambda declarations only one of lcname or rtd_key is present.) This frees up op2, which is now used to reference the parent ce VAR in inheriting declarations. The jmp offset for anon class declarations is moved frop op2 to extended_value. The changes were applied both to class and function declarations to keep everything symmetric.

Introduce BIND_LEXICAL This opcodes inserts a local CV into the closure static variable table. This replaces the previous mechanism of having static variables marked as LEXICAL, which perform a symtable lookup during copying. This means a) functions which contain closures no longer have to rebuild their symtable (better performance) and b) we can now track used variables in SSA.
