   HI16_SLO is for the add3 and load/store with displacement instructions.
   HI16_ULO is for the or3 instruction.
   For R_M32R_HI16_SLO, the lower 16 bits are sign extended when added to
   the high 16 bytes so if the lower 16 bits are negative (bit 15 == 1) then
   we must add one to the high 16 bytes (which will get subtracted off when
   the low 16 bits are added).
   These relocs have to be done in combination with an R_M32R_LO16 reloc
   because there is a carry from the LO16 to the HI16.  Here we just save
   the information we need; we do the actual relocation when we see the LO16.
   This code is copied from the elf32-mips.c.  We also support an arbitrary
   number of HI16 relocs to be associated with a single LO16 reloc.  The
   assembler sorts the relocs to ensure each HI16 immediately precedes its
   LO16.  However if there are multiple copies, the assembler may not find
   the real LO16 so it picks the first one it finds.  */

/* Relocate an M32R/D ELF section.
   There is some attempt to make this function usable for many architectures,
   both for RELA and REL type relocs, if only to serve as a learning tool.

   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 adjust 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.  */

     default kind of relocations.  But, we may actually need both
     kinds of relocations, so we set up the second header here.

     This is not necessary for the O32 ABI since that only uses Elf32_Rel
     relocations (cf. System V ABI, MIPS RISC Processor Supplement,
     3rd Edition, p. 4-17).  It breaks the IRIX 5/6 32-bit ld, since one
     of the resulting empty .rela.<section> sections starts with
     sh_offset == object size, and ld doesn't allow that.  While the check
     is arguably bogus for empty or SHT_NOBITS sections, it can easily be
     avoided by not emitting those useless sections in the first place.  */
