Flushing speculative instruction processing

摘要

Technical solutions are described for avoiding a transaction abort in a multiprocessor that supports transactional memory during out-of-order execution of an instruction stream. An example method described includes detecting an instruction that represents an end of a transaction in the instruction stream. The method also includes identifying a conflict in execution of an outside instruction in conjunction with execution of the transaction, the outside instruction being after instruction that represents the end of the transaction, and where the conflict causes the transaction to abort. The method also includes flushing the outside instruction; and resuming the execution of the transaction, without aborting the transaction.
