[bfd/ChangeLog] * coff-i860.c (coff_i860_reloc_nyi): New function. (howto_table): Add entries for relocations PAIR, HIGHADJ, HIGH, LOWn, SPLITn, and BRADDR. (RTYPE2HOWTO): Check that the r_type is within the howto_table before trying to access the entry. (coff_i860_rtype_to_howto): Likewise. (coff_i860_reloc_type_lookup): New function. (i860_reloc_processing): New function. (coff_bfd_reloc_type_lookup): Define macro. (RELOC_PROCESSING): Define macro. Minor formatting adjustments. [include/coff/ChangeLog] * coff/i860.h (COFF860_R_PAIR, COFF860_R_LOW0, COFF860_R_LOW1, COFF860_R_LOW2, COFF860_R_LOW3, COFF860_R_LOW4, COFF860_R_SPLIT0, COFF860_R_SPLIT1, COFF860_R_SPLIT2, COFF860_R_HIGHADJ, COFF860_R_BRADDR): Define new relocation constants and document.
