@@ -29,37 +29,6 @@ PHP 5.5 UPGRADE NOTES - php_logo_guid(), php_egg_logo_guid(), php_real_logo_guid() and zend_logo_guid() have been removed - Removal of Logo GUIDs -- extensions can't override zend_execute() any more, they should override - zend_execute_ex() instead. The EG(current_execute_data) is already - initialized in zend_execute_ex(), so for compatibility extensions - may need to use EG(current_execute_data)->prev_execute_data instead. -- removed EG(arg_types_stack), EX(fbc), EX(called_scope), EX(current_object) -- added op_array->nested_calls. It's calculated at compile time. -- added EX(call_slots). It is an array to store information about syntaticaly - nested calls (e.g. foo(bar())). It's preallocated together with execute_data. -- added EX(call) - pointer to a current calling function. Actually an - element of EX(call_slots) -- opcodes INIT_METHOD_CALL, ZEND_INIT_STATIC_METHOD_CALL, - ZEND_INIT_FCALL_BY_NAME, ZEND_INIT_NS_FCALL_BY_NAME use result.num as - an index in EX(call_slots) -- opcode ZEND_NEW uses extended_vallue as an index in EX(call_slots) -- opcoes ZEND_DO_FCALL and ZEND_DO_FCALL_BY_NAME use op2.num as - an index in EX(call_slots) -- added op_array->used_stack. It's calculated at compile time and the - corresponding stack space is preallocated together with execute_data. - ZEND_SEND* and ZEND_DO_FCALL* don't need to check for stack overflow - anymore. -- Removed execute_data->Ts field. The VM temporary variables always allocated - immediately before execute_data structure. Now they are accessed by offset - from the execute_data base pointer (instead of execute_data->Ts). Compiler - stores new offsets in op_array->opcodes[*].op?.num. You can use macros - EX_TMP_VAR() and EX_TMP_VAR_NUM() to access temp_variable by offset or - number. You can convert number to offset using EX_TMP_VAR_NUM(0, num) or - offset to number (EX_TMP_VAR_NUM(0,0)-EX_TMP_VAR(0,offset)). -- Removed execute_data->CVs field. The VM compiled variables always allocated - immediately after execute_data structure. Now they are accessed by offset - from the execute_data base pointer (instead of execute_data->CVs). You can - use macros EX_CV_NUM() to access compiled variables by number. ======================================== 2. New Features |
