 * Relocation types used in the sparc implementation.  Relocation entries for
 * things other than instructions use the same generic relocation as discribed
 * in <mach-o/reloc.h> and their r_type is SPARC_RELOC_VANILLA.  The rest of the
 * relocation types are for instructions.  Since they are for instructions the
 * r_address field indicates the 32 bit instruction that the relocation is to
 * be preformed on.  The field r_pcrel is set only for the SPARC_RELOC_WDISP22
 * and SPARC_RELOC_WDISP30.  And r_length is set to long for all
 * non-RELOC_VANILLA r_types.
