   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

   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

/* Relocate an M32R/D ELF section.
   There is some attempt to make this function usable for many architectures,
   both USE_REL and USE_RELA ['twould be nice if such a critter existed],
   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
   relocateable 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 relocateable 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.  */

#if 0 /* relaxing not supported yet */

/* This function handles relaxing for the m32r.
   Relaxing on the m32r is tricky because of instruction alignment
   requirements (4 byte instructions must be aligned on 4 byte boundaries).

   The following relaxing opportunities are handled:

   seth/add3/jl -> bl24 or bl8
   seth/add3 -> ld24

   It would be nice to handle bl24 -> bl8 but given:

   - 4 byte insns must be on 4 byte boundaries
   - branch instructions only branch to insns on 4 byte boundaries

   this isn't much of a win because the insn in the 2 "deleted" bytes
   must become a nop.  With some complexity some real relaxation could be
   done but the frequency just wouldn't make it worth it; it's better to
   try to do all the code compaction one can elsewhere.
   When the chip supports parallel 16 bit insns, things may change.
