Abstract:
The described embodiments include a processor with a fault status register (FSR) that executes a Confirm instruction. In these embodiments, when executing the Confirm instruction, the processor receives a predicate vector that includes N elements. For a first set of bit positions in the FSR for which corresponding elements of the predicate vector are active, the processor determines if at least one of the first set of bit positions in the FSR holds a predetermined value. When at least one of the first set of bit positions in the FSR holds the predetermined value, the processor causes a fault in the processor.
