* output.h (Output_reloc<SHT_REL>::Output_reloc): Add
is_symbolless parameter. (Output_reloc<SHT_REL>::is_symbolless): New. (Output_reloc<SHT_REL>::is_symbolless_): New. (Output_reloc<SHT_REL>::type_): Decrease to 29 bits. (Output_reloc<SHT_RELA>::Output_reloc): Add is_symbolless parameter. (Output_reloc<SHT_RELA>::is_symbolless): New. (Output_data_reloc::add_global): Handle is_symbolless. (Output_data_reloc::add_global_relative): Likewise. (Output_data_reloc::add_local): Likewise. (Output_data_reloc::add_local_relative): Likewise. (Output_data_reloc::add_symbolless_global_addend): New. (Output_data_reloc::add_symbolless_local_addend): New. * output.cc (Output_reloc<SHT_REL>::Output_reloc): Handle is_symbolless. (Output_reloc::set_needs_dynsym_index): Test ->is_symbolless_ instead of ->is_relative_ (Output_reloc::write): Likewise. (Output_reloc::get_symbol_index): Return 0 when ->is_symbolless_ (Output_reloc::write_rel): Simplify. * sparc.cc (Target_sparc::Scan::local): Use ->add_symbolless_local_addend as needed. (Target_sparc::Scan::global): Use ->add_symbolless_global_addend as needed. Also, emit appropriate unaligned vs. aligned dynamic reloc based upon relocation offset.
