Abstract

Official abstract text for this publication.

A method and apparatus for controlling a processor to execute in a single step mode such that a single instruction from the instruction stream is executed, the processor determines if the single instruction is one of at least one predetermined type of instruction and stores a type indicator in a data storage location and a diagnostic exception is taken after the processor has processed the single instruction. Additionally, a diagnostic operation is performed including accessing the type indicator stored in the data storage location and, when the single instruction was not one of the predetermined type, controlling the processor to continue executing instructions in the single step mode, and, when the single instruction was one of the at least one predetermined type, controlling the processor to exit the single step mode and not execute the next instruction within the instruction stream as a single instruction followed by an exception.
