Bob Weinand	cc876c04b4	Fix too early terminated temporary range with break/cont/goto I have no crashing or leaking reproduce script, only valgrind invalid reads for that one; hence no phpt here	11 years ago
Dmitry Stogov	17c5315bdf	Fixed exception habdling on "return" statement. Such exceptions shouldn't be caught in the same function.	11 years ago
Dmitry Stogov	301ee26568	Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE(). As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.	11 years ago

Aaron Piotrowski	5df893ce3c	Use NULL where possible for exception class Matches usage of zend_throw_exception()/zend_throw_exception_ex().	11 years ago
Dmitry Stogov	5ee8413259	Fixed bug #62210 (Exceptions can leak temporary variables. As a part of the fix serious refactoring was done. op_array->brk_cont_array was removed, and replaced with more general and speed efficient op_array->T_liveliness. ZEND_GOTO opcode is always replaced by ZEND_JMP at compile time).

It's actually the same algorithm with second loop removed and simpler temporary data structures. The only difference may be in "re-defined" vatriable handling.

Nikita Popov	89ce8d28de	Fix crash when exception is thrown during ROPE_END The CHECK_EXCEPTION() was done at a point where the old opline is still used, thus redirecting the write to the result var into EX(call) instead. Handling the exception in-place to avoid leaking result.	11 years ago

Dmitry Stogov	7aa7627172	Use ZSTR_ API to access zend_string elements (this is just renaming without semantick changes).	11 years ago

Nikita Popov	c7f4c5a2fe	Avoid unnecessary separations in VERIFY_RETURN_TYPE	11 years ago
Dmitry Stogov	a524a375d9	Improved class type hints checks, by caching resolved class entries in run-time cache.	11 years ago
Nikita Popov	5d3cf577aa	Make convert_to_* safe with rc>1 This only involves switching zval_dtor to zval_ptr_dtor for arrays and making the convert_to_object for arrays a bit more generic. All the other changes outside zend_operators.c just make use of this new ability (use COPY instead of DUP). What's still missing: Proper references handling. I've seen many convert_to* calls that will break when a reference is used. Also fixes bug #69788.	11 years ago
Dmitry Stogov	51dbf73954	Fetch operands of opceodes for binary operators in certain order (from left to right).	11 years ago
Dmitry Stogov	7f39ee7159	Delay checks for undefined CV variables after checks for fast paths.	11 years ago
Dmitry Stogov	aca6a1a1c9	Convert "switch" into series of "if". This allows better fast-path placement, additional specialization and makes final code less.	11 years ago
Dmitry Stogov	0040efb170	Avoid useless copying and duplication	11 years ago
Dmitry Stogov	f07d770f0b	Specialize out useless checks. Only IS_VAR may be EG(error).	11 years ago

Dmitry Stogov	36c36ee56d	Removed dead code (IS_CONST operand can't be IS_OBJECT)	11 years ago
Dmitry Stogov	544fb5c7bc	Separate rare used increment/decrement/assign_op of overloaded properies into non inlined functions.	11 years ago

Dmitry Stogov	c09698753e	CONCAT optimization	11 years ago
Dmitry Stogov	0d054f5faf	Avoid useless duplication. Constant values have to be duplicated only for internal constants in ZTS build, to prevent simultaneous modification of reference counters from different threads.	11 years ago

Nikita Popov	8542befa7b	Remove ZEND_BRK/ZEND_CONT from VM These are no longer used at run-time now, only temporarily during compilation.	11 years ago
Nikita Popov	9325ada725	Embed break/continue depth into opline Previously a separate lval literal was used - this is probably a leftover from the time where the break level could still be specified dynamically.	11 years ago
Nikita Popov	d0e265392f	Drop FREE_ON_RETURN flag, check brk_cont->start instead Start >= 0 already tells us whether or not the loop has a loop variable, no need to add extra flags to opcodes. Also added a test for a case where FREE_ON_RETURN is relevant, we didn't seem to have any coverage for this.	11 years ago
Dmitry Stogov	d6bcf2bf2e	Micro optimization	11 years ago
Dmitry Stogov	cee88571d9	Fixed bug #69649 (segfault with --enable-dtrace)	11 years ago
