        * 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. */
