* elf32-mips.c (mips_elf_generic_reloc): New Function.
(elf_mips_howto_table_rel): Use it. (gprel32_with_gp): Move prototype. (mips_elf_hi16_reloc): Check for ! BSF_LOCAL instead of zero addend. Use mips_elf_generic_reloc. (mips_elf_got16_reloc): Check for ! BSF_LOCAL instead of zero addend. Code cleanup. (_bfd_mips_elf32_gprel16_reloc): Check for ! BSF_LOCAL instead of zero addend. (mips_elf_gprel32_reloc): Likewise. Use the same GP assignment logic as in the other *_gprel*_reloc functions. (gprel32_with_gp): Handle partial_inplace properly. (mips32_64bit_reloc): Use mips_elf_generic_reloc. (mips16_gprel_reloc): Check for ! BSF_LOCAL instead of zero addend. Do addend handling directly instead of calling _bfd_mips_elf_gprel16_with_gp. Handle partial_inplace properly. * elf64-mips.c (mips_elf64_hi16_reloc): Check for ! BSF_LOCAL instead of zero addend. Handle partial_inplace properly. (mips_elf64_got16_reloc): Check for ! BSF_LOCAL instead of zero addend. (mips_elf64_gprel16_reloc): Likewise. (mips_elf64_literal_reloc): Likewise. (mips_elf64_gprel32_reloc): Likewise. Use the same GP assignment logic as in the other *_gprel*_reloc functions. Handle partial_inplace properly. (mips_elf64_shift6_reloc): Check for ! BSF_LOCAL instead of zero addend. Handle partial_inplace properly. (mips16_gprel_reloc): Likewise. Do addend handling directly instead of calling _bfd_mips_elf_gprel16_with_gp. * elfn32-mips.c (mips_elf_got16_reloc): Check for BSF_LOCAL. (mips_elf_gprel32_reloc): Check for ! BSF_LOCAL instead of zero addend. (mips_elf_shift6_reloc): Handle partial_inplace properly. (mips16_gprel_reloc): Likewise. Do addend handling directly instead of calling _bfd_mips_elf_gprel16_with_gp. * elfxx-mips.c (_bfd_mips_elf_gprel16_with_gp): Handle partial_inplace properly. Fix wrong addend handling. Fix overflow check. (_bfd_mips_elf_sign_extend): Renamed from mips_elf_sign_extend and exported. (mips_elf_calculate_relocation): Use _bfd_mips_elf_sign_extend. (_bfd_mips_elf_relocate_section): Likewise. (mips_elf_create_dynamic_relocation): Update sec_info_type access. * elfxx-mips.h (_bfd_mips_relax_section): Fix prototype declaration. (_bfd_mips_elf_sign_extend): New prototype. * config/tc-mips.c (md_pcrel_from): Return actual pcrel address. (md_apply_fix3): Ignore non-special relocations. Remove superfluous exceptions from size assert. Remove most of the addend fixup specialcasing. Remove value, use valP directly. simplify fx_addnumber handling. Remove zero addend specialcases. (tc_gen_reloc): Use appropriate value for reloc2 addend. Remove the addend fixup specialcase. * config/tc-mips.h (MD_APPLY_SYM_VALUE): Define as 0.
