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. */

252b5132
RH		 2331
2332 The RELOCATE_SECTION function is called by the new ELF backend linker
2333 to handle the relocations for a section.
2334
2335 The relocs are always passed as Rela structures; if the section
2336 actually uses Rel structures, the r_addend field will always be
2337 zero.
2338

2340 necessary, and (if using Rela relocs and generating a
1049f94e 2341 relocatable output file) adjusting the reloc addend as
252b5132
RH		 2342 necessary.
2343
2344 This function does not have to worry about setting the reloc
2345 address or the reloc symbol index.
2346
2347 LOCAL_SYMS is a pointer to the swapped in local symbols.
2348
2349 LOCAL_SECTIONS is an array giving the section in the input file
2350 corresponding to the st_shndx field of each local symbol.
2351
2352 The global hash table entry for the global symbols can be found
2353 via elf_sym_hashes (input_bfd).
2354
1049f94e 2355 When generating relocatable output, this function must handle
252b5132
RH		 2356 STB_LOCAL/STT_SECTION symbols specially. The output symbol is
2357 going to be the section symbol corresponding to the output
2358 section, which means that the addend must be adjusted
