int
getSqrtRefinementSteps(
EVT VT,
MachineFunction& MF) const;Return the refinement step count for a square root of the given type based on the function's attributes. If the operation is not overridden by the function's attributes, "Unspecified" is returned and target defaults are expected to be used for instruction selection.
