* . The VM stacks for passing function arguments and syntaticaly nested calls ↵Dmitry Stogov2012-11-301-11/+91
| | | | | | were merged into a single stack. The stack size needed for op_array execution is calculated at compile time and preallocated at once. As result all the stack push operatins don't require checks for stack overflow any more. . Generators implementation was improved using the new VM stack. Now it's a bit more clear and faster.

* | | Remove asterix modifier (*) for generatorsNikita Popov2012-07-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Generators are now automatically detected by the presence of a `yield` expression in their body. This removes the ZEND_SUSPEND_AND_RETURN_GENERATOR opcode. Instead additional checks for ZEND_ACC_GENERATOR are added to the fcall_common helper and zend_call_function. This also adds a new function zend_generator_create_zval, which handles the actual creation of the generator zval from an op array. I feel like I should deglobalize the zend_create_execute_data_from_op_array code a bit. It currently changes EG(current_execute_data) and EG(opline_ptr) which is somewhat confusing (given the name).
* | | Make the GOTO and SWITCH VMs work againNikita Popov2012-05-291-4/+3

* | | Add support for executing a zend_execute_dataNikita Popov2012-05-261-33/+42
| | | | | | | | | | | | | | | | | | | | | | | | This adds another function execute_ex(), which accepts a zend_execute_data struct to run (contrary to execute(), which accepts a zend_op_array from which it initialized the execute_data). This needs a bit more cleanup.
* | | Allocate execute_data using malloc for generatorsNikita Popov2012-05-221-4/+32
|/ / | | | | | | | | | | | | Generators need to switch the execute_data very often. If the execute_data is allocated on the VM stack this operation would require to always copy the structure (which is quite large). That's why the execution context is allocated on the heap instead (only for generators obviously).
* | - Improved memory usageDmitry Stogov2010-09-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | . zend_function.pass_rest_by_reference is replaced by ZEND_ACC_PASS_REST_BY_REFERENCE in zend_function.fn_flags . zend_function.return_reference is replaced by ZEND_ACC_RETURN_REFERENCE in zend_function.fn_flags . zend_arg_info.required_num_args removed. it was needed only for internal functions. Now the first arg_info for internal function (which has special meaning) is represented by zend_internal_function_info structure. . zend_op_array.size, size_var, size_literal, current_brk_cont, backpatch_count moved into CG(context), because they are used only during compilation. . zend_op_array.start_op is moved into EG(start_op), because it's used only for 'interactive' execution of single top-level op-array. . zend_op_array.done_pass_two is replaced by ZEND_ACC_DONE_PASS_TWO in zend_op_array.fn_flags. . op_array.vars array is trimmed (reallocated) during pass_two. . zend_class_entry.constants_updated is replaced by ZEND_ACC_CONSTANTS_UPDATED in zend_class_entry.ce_flags . the size of zend_class_entry is reduced by sharing the same memory space by different information for internal and user classes. See zend_class_inttry.info union.
