Floating-Point Equal Quad-Precision

This instruction is defined by:

Encoding

Synopsis

The feq.q performs the specified comparison between floating-point registers fs1 and fs2, and writes 1 to integer register xd if the conditon hold, and 0 otherwise.

feq.q performs a quiet comparison: it only sets the invalid operation exception flag if either input is a signaling NaN. The result is 0 if either operand is NaN.
