ef20d2990f Remove unnecessary CE_STATIC_MEMBERS() checks 
CE_STATIC_MEMBERS(ce) is destroyed after EG(active)=0 is set, so we
should never run into a situation where it is NULL inside the VM.

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

e0171ed9d0 Avoid another unused opline warning 
The unconditional opline load here used to be necessary for freeing
the return value in case of exception. However, this is no longer
the case, so using LOAD_OPLINE() should be sufficient now.

7141631cc8 Change FETCH/ISSET instruction modifiers: 
- Get rid of ZEND_ISEMPTY and ZEND_ISSET_ISEMPTY_MASK. Use just single ZEND_ISSET bit to make distinct between isset() and empty()
- Use ZEND_FETCH_GLOBAL, ZEND_FETCH_LOCAL and ZEND_FETCH_GLOBAL_LOCK as bitmask
- Removed unused ZEND_FETCH_STANDARD
- Extended ZEND_FETCH_ARG_MASK

fd30c59e04 Fixed bug #75786 
SEND_UNPACK on iterators was duplicating references in-place,
which effectively leaks the original value and causes an off-by-one
refcount on the duplicated value.

Replace this with a deref, as an actual duplication is not even
needed in this case.

91507ba6e8 Reduced VM code size. 
Made FETCH_DIM/OBJ_FUNC_ARG to dispatch ro corresponding FETCH_DIM/OBJ_R/_W handlers.
Merged TMP and VAR specializations of ZEND_FETCH_OBJ_R.
Allowed dispatching to less specialized handelrs and helpers. (e.g. from OP_TMP_CONST to OP_TMPVAR_CONST).
