Abstract
Transactional execution branch indications are placed into one or more transaction diagnostic blocks when a transaction is aborted. Each branch indication specifies whether a branch was taken, as a result of executing a branch instruction within the transaction. As the transaction executes and a branch instruction is encountered, a branch indication is set in a vector indicating whether the branch was taken. Then, if the transaction aborts, the indicators are stored in one or more transaction diagnostic blocks providing a branch history usable in diagnosing the failure.
