/*
* 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.
