        * coff-mips.c (mips_relhi_reloc, mips_rello_reloc)
        (mips_switch_reloc, mips_read_relocs, mips_relax_section)
        (mips_relax_pcrel16, PCREL16_EXPANSION_ADJUSTMENT): Remove.
        (mips_relocate_hi): Remove now-unused 'adjust' and 'pcrel' arguments,
        and update comments to reflect current usage.
        (mips_howto_table): Remove entries for MIPS_R_RELHI, MIPS_R_RELLO,
        and MIPS_R_SWITCH, as well as several empty entries.  Update comment
        for MIPS_R_PCREL16.
        (mips_ecoff_swap_reloc_in, mips_ecoff_swap_reloc_out)
        (mips_adjust_reloc_out, mips_bfd_reloc_type_lookup): Remove support
        for MIPS_R_SWITCH, MIPS_R_RELLO, and MIPS_R_RELHI relocations.
        (mips_adjust_reloc_in): Likewise, adjust maximum accepted relocation
        type number to be MIPS_R_PCREL16.
        (mips_relocate_section): Remove support for link-time relaxation
        of branches used by embedded-PIC.  Remove support for MIPS_R_SWITCH,
        MIPS_R_RELLO, and MIPS_R_RELHI relocations.
        (_bfd_ecoff_bfd_relax_section): Redefine to bfd_generic_relax_section.
        * ecoff.c (ecoff_indirect_link_order): Remove support for link-time
        relaxation of branches used by embedded-PIC.
        * ecofflink.c (bfd_ecoff_debug_accumulate): Likewise.
        * libecoff.h (struct ecoff_section_tdata): Remove embedded-PIC
        related members, update comment.
        * pe-mips.c: Remove disabled (commented-out and #if 0'd)
        code related to embedded-PIC.
        * elfxx-mips.c (_bfd_mips_elf_read_ecoff_info): Remove
        initialization of now-removed 'adjust' member of
        'struct ecoff_debug_info'.

-/* This reloc type is a Cygnus extension used when generating position
-   independent code for embedded systems.  It is used for an entry in
-   a switch table, which looks like this:
-     .word $L3-$LS12
-   The object file will contain the correct difference, and does not
-   require adjustment.  However, when the linker is relaxing PC
-   relative calls, it is possible for $L3 to move farther away.  This
-   reloc always appears in the .text section, and is always against
-   the .text section.  However, the symbol index is not
-   RELOC_SECTION_TEXT.  It is, instead, the distance between this
-   switch table entry and $LS12.  Thus, the original value of $L12 is
-     vaddr - symndx
-   and the original value of $L3 is
-     vaddr - symndx + addend
-   where addend is the value in the object file.  Knowing this, the
-   linker can know whether the addend in the object file must be
-   adjusted.  */
