Subject:         * elf-hppa.h (elf_hppa_final_link_relocate): Handle DLTREL14R and
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=79acc8018baa2ef8497f48983c488faaf4da75d5;p=pf3gnuchains%2Fpf3gnuchains3x.git

    * elf-hppa.h (elf_hppa_final_link_relocate): Handle DLTREL14R and
        DLTREL21L relocs.  Pass the output bfd to elf_hppa_relocate_insn.
        Pass the relocate type rather than the insn format to
        elf_hppa_relocate_insn.
        (elf_hppa_relocate_insn): Make switch dependent on relocation type
        rather than the opcode.  Handle DLTREL21L and DLTREL14R relocs.
