Browse source 
(TC_DWARF2_EMIT_OFFSET): Provide default.
        (out_debug_aranges, out_debug_info): Use it.
        * config/tc-ia64.c (ia64_dwarf2_emit_offset): New.
        (ia64_cons_fix_new): Move FUNC_DTP_RELATIVE handling ...
        (ia64_gen_real_reloc_type): ... here.
        * config/tc-ia64.h (TC_DWARF2_EMIT_OFFSET): New.
