+/* The ns32k series is ah, unusual, when it comes to relocation.
+ * There are three storage methods for relocateable objects. There
+ * are displacements, immediate operands and ordinary twos complement
+ * data. Of these, only the last fits into the standard relocation
+ * scheme. Immediate operands are stored huffman encoded and
+ * immediate operands are stored big endian (where as the natural byte
+ * order is little endian for this achitecture).
+
+ * Note that the ns32k displacement storage method is orthogonal to
+ * whether the relocation is pc relative or not. The "displacement"
+ * storage scheme is used for essentially all address constants. The
+ * displacement can be relative to zero (absolute displacement),
+ * relative to the pc (pc relative), the stack pointer, the frame
+ * pointer, the static base register and general purpose register etc.
+
+ * For example:
+ *
+ * sym1: .long . # pc relative 2's complement
+ * sym1: .long foo # 2's complement not pc relative
+ *
+ * self: movd @self, r0 # pc relative displacement
+ * movd foo, r0 # non pc relative displacement
+ *
+ * self: movd self, r0 # pc relative immediate
+ * movd foo, r0 # non pc relative immediate
+ *
+ * In addition, for historical reasons the encoding of the relocation types
+ * in the a.out format relocation entries is such that even the relocation
+ * methods which are standard are not encoded the standard way.
