ABSTRACT:
One embodiment of the present invention provides a system that reports reasons for failure during transactional execution. During operation, the system transactionally executes a block of instructions in a program. If the transactional execution of the block of instructions completes successfully, the system commits changes made during the transactional execution, and resumes normal non-transactional execution of the program past the block of instructions. Otherwise, if transactional execution of the block of instructions fails, the system discards changes made during the transactional execution, and records failure information indicating why the transactional execution failed.
