| * Improved traits implementation. Now to support __CLASS__ constant in traits ↵Dmitry Stogov2012-01-171-4/+4
| | | | | | | | php doesn't have to copy the complete compiled method, but can reuse the same code. The resolution of __CLASS__ constants in methods defined in traits are delayed till run-time. This approach also made possible to use __CLASS__ constant as default value for traits properties and method arguments.

* | Optimized access to temporary and compiled VM variablesDmitry Stogov2012-12-041-9/+9
| |
* | . The VM stacks for passing function arguments and syntaticaly nested calls ↵Dmitry Stogov2012-11-301-8/+6
| | | | | | | | | | | | 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.

* | Replace code with zend_clean_and_cache_symbol_table() callNikita Popov2012-09-161-9/+1
| | | | | | | | | | I replaced other instances of this code with the function call, but missed this one.
* | Remove asterix modifier (*) for generatorsNikita Popov2012-07-201-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* - Improved memory usageDmitry Stogov2010-09-151-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | . 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.
* - use interned strings for auto globalsDmitry Stogov2010-07-081-10/+0
