b0af9ac733 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.

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

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

12c386f5b9 Use ZEND_CLOSURE_OBJECT() macro to resolve closure op_array to closure object through address calculation, instead of op_array->prototype reuse. (reapply 781e1573af, now it should be OK). 2018-01-11 22:15:45 +03:00

6b258197e8 Fix zend_fetch_dimension_const() 
Pass IS_TMP_VAR instead of IS_CONST as operand type, as IS_CONST
requires additional guarantees that are not necessarily
satisfied by the caller.

Add _unchecked() variants of zend_spprintf and zend_strpprintf for
cases where we specifically want to disable these checks, such as
use of %H.

49ea143bbd Encapsulate reference-counting primitives. 
Prohibit direct update of GC_REFCOUNT(), GC_SET_REFCOUNT(), GC_ADDREF() and GC_DELREF() shoukf be instead.
Added mactros to validate reference-counting (disabled for now).
These macros are going to be used to eliminate race-condintions during reference-counting on data shared between threads.
