+ * Ok.  Following are the relocation information macros.  If your

+ * of structure that is stored in the relocation info section of your
+ * a.out files.  Often this is defined in the a.out.h for your system.
+ *
+ *   RELOC_ADDRESS (rval): Offset into the current section of the
+ * <whatever> to be relocated.  *Must be an lvalue*.
+ *
+ *   RELOC_EXTERN_P (rval):  Is this relocation entry based on an
+ * external symbol (1), or was it fully resolved upon entering the
+ * loader (0) in which case some combination of the value in memory
+ * (if RELOC_MEMORY_ADD_P) and the extra (if RELOC_ADD_EXTRA) contains
+ * what the value of the relocation actually was.  *Must be an lvalue*.
+ *
+ *   RELOC_TYPE (rval): If this entry was fully resolved upon
+ * entering the loader, what type should it be relocated as?
+ *
+ *   RELOC_EXTENDED_TYPE (rval): If this entry is for a machine using
+ * extended relocatino, what type of field is it?  (For example, on RISC
+ * machines, odd-sized displacements or split displacements occur.)
+ *
+ *   RELOC_SYMBOL (rval): If this entry was not fully resolved upon
+ * entering the loader, what is the index of it's symbol in the symbol
+ * table?  *Must be a lvalue*.
+ *
+ *   RELOC_MEMORY_ADD_P (rval): This should return true if the final
+ * relocation value output here should be added to memory, or if the
+ * section of memory described should simply be set to the relocation
+ * value.
+ *
+ *   RELOC_ADD_EXTRA (rval): (Optional) This macro, if defined, gives
+ * an extra value to be added to the relocation value based on the
+ * individual relocation entry.  *Must be an lvalue if defined*.
+ *
+ *   RELOC_PCREL_P (rval): True if the relocation value described is
+ * pc relative.
+ *
+ *   RELOC_VALUE_RIGHTSHIFT (rval): Number of bits right to shift the
+ * final relocation value before putting it where it belongs.
+ *
+ *   RELOC_TARGET_SIZE (rval): log to the base 2 of the number of
+ * bytes of size this relocation entry describes; 1 byte == 0; 2 bytes
+ * == 1; 4 bytes == 2, and etc.  This is somewhat redundant (we could
+ * do everything in terms of the bit operators below), but having this
+ * macro could end up producing better code on machines without fancy
+ * bit twiddling.  Also, it's easier to understand/code big/little
+ * endian distinctions with this macro.
+ *
+ *   RELOC_TARGET_BITPOS (rval): The starting bit position within the
+ * object described in RELOC_TARGET_SIZE in which the relocation value
+ * will go.
+ *
+ *   RELOC_TARGET_BITSIZE (rval): How many bits are to be replaced
+ * with the bits of the relocation value.  It may be assumed by the
+ * code that the relocation value will fit into this many bits.  This
+ * may be larger than RELOC_TARGET_SIZE if such be useful.
+ *
+ *
+ *		Things I haven't implemented
+ *		----------------------------
+ *
+ *    Values for RELOC_TARGET_SIZE other than 0, 1, or 2.

+ *    Pc relative relocation for External references.
