        * config/tc-sparc.c (sparc_ip): Allow OLO10 relocations
        on -64 and not pic.
        (output_insn): Put OLO10's secondary addend into tc_fix_data.
        (md_apply_fix3): Handle BFD_RELOC_SPARC_OLO10.
        (tc_gen_reloc): Return two relocs for OLO10, LO10 and SPARC13.
        * config/tc-sparc.h (RELOC_EXPANSION_POSSIBLE,
        MAX_RELOC_EXPANSION): Define.
        (TC_FIX_TYPE, TC_INIT_FIX_DATA, TC_FIX_DATA_PRINT): Likewise.
