Abstract

Instruction interrupt suppression for an overflow condition. An instruction is executed, and a determination is made that an overflow condition occurred. Based on a per-instruction overflow interrupt indicator being set to a defined value, interrupt processing for the overflow condition is performed, and based on the per-instruction overflow interrupt indicator being set to another defined value, the interrupt processing for the overflow condition is bypassed.
