Abstract:
One embodiment provides a system that facilitates the execution of a transaction for a program in a hardware-supported transactional memory system. During operation, the system records a misspeculation indicator of the transaction during execution of the transaction using hardware transactional memory mechanisms. Next, the system detects a transaction failure associated with the transaction. Finally, the system provides the recorded misspeculation indicator to the program to facilitate a response to the transaction failure by the program.
