- * To make scattered loading by the link editor work correctly "local"
- * relocation entries can't be used when the item to be relocated is the value
- * of a symbol plus an offset (where the resulting expresion is outside the
- * block the link editor is moving, a blocks are divided at symbol addresses).
- * In this case. where the item is a symbol value plus offset, the link editor
- * needs to know more than just the section the symbol was defined. What is
- * needed is the actual value of the symbol without the offset so it can do the
- * relocation correctly based on where the value of the symbol got relocated to
- * not the value of the expression (with the offset added to the symbol value).
- * So for the NeXT 2.0 release no "local" relocation entries are ever used when
- * there is a non-zero offset added to a symbol. The "external" and "local"
- * relocation entries remain unchanged.
- *
- * The implemention is quite messy given the compatibility with the existing
- * relocation entry format. The ASSUMPTION is that a section will never be
- * bigger than 2**24 - 1 (0x00ffffff or 16,777,215) bytes. This assumption
- * allows the r_address (which is really an offset) to fit in 24 bits and high
- * bit of the r_address field in the relocation_info structure to indicate
- * it is really a scattered_relocation_info structure. Since these are only
- * used in places where "local" relocation entries are used and not where
- * "external" relocation entries are used the r_extern field has been removed.
- *
- * For scattered loading to work on a RISC machine where some of the references
- * are split across two instructions the link editor needs to be assured that
- * each reference has a unique 32 bit reference (that more than one reference is
- * NOT sharing the same high 16 bits for example) so it move each referenced
