Allow throwing exceptions from generators The missing piece is how one can find the next stack frame, which is required for dtor'ing arguments pushed to the stack. As the generator execute_data does not live on the stack one can't use it to figure out the start of the next stack frame. So there must be some other method. 2012-05-30 14:28:33 +00:00			`--TEST--`

Remove asterix modifier (*) for generators 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). 2012-07-19 22:49:50 +00:00			`function gen() {`
