摘要：
A load is executed speculatively as a dismissible load instruction, which does not take exceptions, and a check instruction, which is in the same format as the dismissible load, that when executed determines whether an exception should be taken on the dismissible load. In this manner, a load may be executed speculatively while ensuring that an exception occurs at the same time it would have occurred had the load been executed non-speculatively.
