Abstract
Setting or updating of floating point controls is managed. Floating point controls include controls used for floating point operations, such as rounding mode and/or other controls. Further, floating point controls include status associated with floating point operations, such as floating point exceptions and/or others. The management of the floating point controls includes efficiently updating the controls, while reducing costs associated therewith.
Claims10
A computer-implemented method of facilitating processing within a computing environment, the computer-implemented method comprising:
- obtaining a user-specified value for a floating point exception control for a selected instruction to be processed, the floating point exception control indicating a particular event;
- determining, based on the user-specified value and another value for the floating point exception control provided by a centralized status exception control, an enablement control for the floating point exception control, wherein the determining comprises combining the user-specified value and the other value to provide a value for the enablement control;
- and
- executing the selected instruction, wherein an indication of a floating point exception associated with execution of the selected instruction is enabled or disabled based on the value of the enablement control.
