public static AMD64Address.Scale fromShift(int shift)

Creates a AMD64Address.Scale for the log2 scaling factor shift.

Throws:

IllegalArgumentException - if shift is an unsupported scaling factor

isScaleSupported

public static boolean isScaleSupported(int scale)

Determines if the scaling factor scale is supported.

isScaleShiftSupported

public static boolean isScaleShiftSupported(int shift)

Determines if the log2 scaling factor shift is supported.
