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

2134 The RELOCATE_SECTION function is called by the new ELF backend linker
2135 to handle the relocations for a section.

2143 relocatable output file) adjusting the reloc addend as
2144 necessary.

2146 This function does not have to worry about setting the reloc
2147 address or the reloc symbol index.
2148
2149 LOCAL_SYMS is a pointer to the swapped in local symbols.
2150
2151 LOCAL_SECTIONS is an array giving the section in the input file
2152 corresponding to the st_shndx field of each local symbol.
2153
2154 The global hash table entry for the global symbols can be found
2155 via elf_sym_hashes (input_bfd).
2156
2157 When generating relocatable output, this function must handle
2158 STB_LOCAL/STT_SECTION symbols specially. The output symbol is
2159 going to be the section symbol corresponding to the output
2160 section, which means that the addend must be adjusted
