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		 2319
2320 The RELOCATE_SECTION function is called by the new ELF backend linker

252b5132

2331
2332 This function does not have to worry about setting the reloc
2333 address or the reloc symbol index.

2335 LOCAL_SYMS is a pointer to the swapped in local symbols.
2336
2337 LOCAL_SECTIONS is an array giving the section in the input file

2339
2340 The global hash table entry for the global symbols can be found
2341 via elf_sym_hashes (input_bfd).
2342
1049f94e 2343 When generating relocatable output, this function must handle
252b5132
RH		 2344 STB_LOCAL/STT_SECTION symbols specially. The output symbol is
2345 going to be the section symbol corresponding to the output
2346 section, which means that the addend must be adjusted
