/* Relocate an FRV ELF section.

   The RELOCATE_SECTION function is called by the new ELF backend linker
   to handle the relocations for a section.

   The relocs are always passed as Rela structures; if the section
   actually uses Rel structures, the r_addend field will always be
   zero.

   This function is responsible for adjusting the section contents as
   necessary, and (if using Rela relocs and generating a relocatable
   output file) adjusting the reloc addend as necessary.

   This function does not have to worry about setting the reloc
   address or the reloc symbol index.

   LOCAL_SYMS is a pointer to the swapped in local symbols.

   LOCAL_SECTIONS is an array giving the section in the input file
   corresponding to the st_shndx field of each local symbol.

   The global hash table entry for the global symbols can be found
   via elf_sym_hashes (input_bfd).

   When generating relocatable output, this function must handle
   STB_LOCAL/STT_SECTION symbols specially.  The output symbol is
   going to be the section symbol corresponding to the output
   section, which means that the addend must be adjusted
   accordingly.  */

/* Look through the relocs for a section during the first phase.

   Besides handling virtual table relocs for gc, we have to deal with
   all sorts of PIC-related relocations.  We describe below the
   general plan on how to handle such relocations, even though we only
   collect information at this point, storing them in hash tables for
   perusal of later passes.

   32 relocations are propagated to the linker output when creating
   position-independent output.  LO16 and HI16 relocations are not
   supposed to be encountered in this case.

   LABEL16 should always be resolvable by the linker, since it's only
   used by branches.

   LABEL24, on the other hand, is used by calls.  If it turns out that
   the target of a call is a dynamic symbol, a PLT entry must be
   created for it, which triggers the creation of a private function
   descriptor and, unless lazy binding is disabled, a lazy PLT entry.

   GPREL relocations require the referenced symbol to be in the same
   segment as _gp, but this can only be checked later.

   All GOT, GOTOFF and FUNCDESC relocations require a .got section to
   exist.  LABEL24 might as well, since it may require a PLT entry,
   that will require a got.

   Non-FUNCDESC GOT relocations require a GOT entry to be created
   regardless of whether the symbol is dynamic.  However, since a
   global symbol that turns out to not be exported may have the same
   address of a non-dynamic symbol, we don't assign GOT entries at
   this point, such that we can share them in this case.  A relocation
   for the GOT entry always has to be created, be it to offset a
   private symbol by the section load address, be it to get the symbol
   resolved dynamically.

   FUNCDESC GOT relocations require a GOT entry to be created, and
   handled as if a FUNCDESC relocation was applied to the GOT entry in
   an object file.

   FUNCDESC relocations referencing a symbol that turns out to NOT be
   dynamic cause a private function descriptor to be created.  The
   FUNCDESC relocation then decays to a 32 relocation that points at
   the private descriptor.  If the symbol is dynamic, the FUNCDESC
   relocation is propagated to the linker output, such that the
   dynamic linker creates the canonical descriptor, pointing to the
   dynamically-resolved definition of the function.

   Non-FUNCDESC GOTOFF relocations must always refer to non-dynamic
   symbols that are assigned to the same segment as the GOT, but we
   can only check this later, after we know the complete set of
   symbols defined and/or exported.

   FUNCDESC GOTOFF relocations require a function descriptor to be
   created and, unless lazy binding is disabled or the symbol is not
   dynamic, a lazy PLT entry.  Since we can't tell at this point
   whether a symbol is going to be dynamic, we have to decide later
   whether to create a lazy PLT entry or bind the descriptor directly
   to the private function.

   FUNCDESC_VALUE relocations are not supposed to be present in object
   files, but they may very well be simply propagated to the linker
   output, since they have no side effect.


   A function descriptor always requires a FUNCDESC_VALUE relocation.
   Whether it's in .plt.rel or not depends on whether lazy binding is
   enabled and on whether the referenced symbol is dynamic.

   The existence of a lazy PLT requires the resolverStub lazy PLT
   entry to be present.


   As for assignment of GOT, PLT and lazy PLT entries, and private
   descriptors, we might do them all sequentially, but we can do
   better than that.  For example, we can place GOT entries and
   private function descriptors referenced using 12-bit operands
   closer to the PIC register value, such that these relocations don't
   overflow.  Those that are only referenced with LO16 relocations
   could come next, but we may as well place PLT-required function
   descriptors in the 12-bit range to make them shorter.  Symbols
   referenced with LO16/HI16 may come next, but we may place
   additional function descriptors in the 16-bit range if we can
   reliably tell that we've already placed entries that are ever
   referenced with only LO16.  PLT entries are therefore generated as
   small as possible, while not introducing relocation overflows in
   GOT or FUNCDESC_GOTOFF relocations.  Lazy PLT entries could be
   generated before or after PLT entries, but not intermingled with
   them, such that we can have more lazy PLT entries in range for a
   branch to the resolverStub.  The resolverStub should be emitted at
   the most distant location from the first lazy PLT entry such that
   it's still in range for a branch, or closer, if there isn't a need
   for so many lazy PLT entries.  Additional lazy PLT entries may be
   emitted after the resolverStub, as long as branches are still in
   range.  If the branch goes out of range, longer lazy PLT entries
   are emitted.

   We could further optimize PLT and lazy PLT entries by giving them
   priority in assignment to closer-to-gr17 locations depending on the
   number of occurrences of references to them (assuming a function
   that's called more often is more important for performance, so its
   PLT entry should be faster), or taking hints from the compiler.
   Given infinite time and money... :-)  */
