a186ac0e47 IS_CONST operands don't have to be separated. Use reference-counting instead of duplication. 
- with opcache all IS_CONST operands are not refcounted (scalars, interned strings or immutable arrays)
- without opcache IS_CONST operands are not shared between processes or threads and may use common reference counters

d0c6c179cd Initialize op_array->run_time_cache on slow path of INIT_FCALL opcode and omit corresponding check on fast path of DO_FCALL. 2016-04-05 00:01:00 +03:00

7abfaac901 Merge zend_execute_data->called_scope into zend_execute_data->This. 
"called_scope" made sense only for static method calls, for dynamic calls it was always equal to the class of $this.
Now EG(This) may store IS_OBJECT + $this or IS_UNUSED + "called_scope" (of course, "called_scope" may be NULL).
Some code might need to be adopted to support this change.
Checks (Z_OBJ(EX(This))) might need to be converted into (Z_TYPE(EX(This)) == IS_OBJECT).

86a1aeed22 Flags ZEND_CALL_RELEASE_THIS and ZEND_CALL_CLOSURE should never be set together. 
Closures keep responsibility for releasing $this theirselves.

commit f4475a2360
Author: Dmitry Stogov <dmitry@zend.com>
Date:   Thu Mar 17 10:00:45 2016 +0300

    Transparently introduce type-specialized opcode handlers.
    This affects only PHP VM, and doesn't change anything else.

44ed1cb5c0 Remove ZEND_CALL_CTOR_RESULT_UNUSED

5faedf5b3e Remove EXT_TYPE_UNUSED in favor of IS_UNUSED 
This means we no longer allocate an unused VAR for the retval of
instructions that support unused results.

Nearly all instructions already used the result variable only if
it was used. The only exception to this was the return value
variable for internal function call results. I've adjusted the code
to use a stack zval for the unused return case now. As we have
retval specialization now, we know that it doesn't matter.

6579e48417 Introduced BIND_STATIC opcode instead of FETCH_R/FETCH_W(static)+ASSIGN/ASSIGN_REF (similar to BIND_GLOBAL). 
In the future we may refer to static variable by index instead of name, to eliminate hash lookup.

baf97b1fcc We don't nees zend_op_array->brk_cont_array at run-time anymore. 
Move zend_op_array->brk_cont_array into CG(context).brk_cont_array.
Use more compact zend_op_array->live_range instead of zend_op_array->brk_cont_array.
Semantic is kept unchanged.

cc3c425af8 Fix bug #70662 
This replaces add_new with update for the RW case. This should not
be problematic for performance, as this branch throws a notice.

Alternatively add_new could also be replaced with add. I went with
update, because it makes $a[0] += 1 behavior the same as
$a[0] = $a[0] + 1.
