Allow yielding during function calls During function calls arguments are pushed onto the stack. Now these are backed up on yield and restored on resume. This requires memcpy'ing them, but there doesn't seem to be any better way to do it. Also this fixes the issue with exceptions thrown during function calls. 2012-05-30 22:00:30 +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() {`
