Abstract: A technique for enforcing the use of designated initializers in structured type initializations may include determining whether structured data type requires designated initialization, determining whether an initialization of a structured variable declared to use the structured data type employs an improper initializer that is inconsistent with said structured data type, and performing a diagnostic action if the initialization comprises an improper initializer.

Abstract: A technique for low-power detection of a grace period for deferring the destruction of a shared data element until pre-existing references to the data element have been removed. A grace period processing action is implemented that requires a response from a processor that may be running a preemptible reader of said shared data element before further grace period processing can proceed. A power and reader status of the processor is also determined. Grace period processing may proceed despite the absence of a response from the processor if the power and reader status indicates that an actual response from the processor is unnecessary.
