FP_IEEE_ENABLES_SET_ Procedure

Summary

The FP_IEEE_ENABLES_SET_ procedure sets the IEEE floating-point trap enable

mask. A set bit (value of one) enables a trap for the particular exception. A zero bit (the

normal value) disables that trap.

Note. This procedure is supported in the G06.06 RVU and all subsequent G-series RVUs. IEEE

floating-point is available on all S-series processors except S70000 servers with NSR-G processors.
