fsgnjn.d

Floating-Point Sign-Inject Negate Double-Precision

This instruction is defined by:

Encoding

Synopsis

The fsgnjn.d instruction produces a result that takes all bits except the sign bit from fs1. The result’s sign bit is opposite of fs2’s sign bit, and the result is written to the destination register `fd. Sign-injection instructions do not set floating-point exception flags, nor do they canonicalize NaNs.
