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. */

2350 LOCAL_SECTIONS is an array giving the section in the input file

2353 The global hash table entry for the global symbols can be found
2354 via elf_sym_hashes (input_bfd).

1049f94e 2356 When generating relocatable output, this function must handle
252b5132
RH
2357 STB_LOCAL/STT_SECTION symbols specially. The output symbol is
2358 going to be the section symbol corresponding to the output
2359 section, which means that the addend must be adjusted

3814 including in the link (i.e., DEF_REGULAR is set). At

3816 possible that DEF_REGULAR is not set now but will be set
3817 later (it is never cleared). We account for that
3818 possibility below by storing information in the
3819 dyn_relocs field of the hash table entry. A similar
3820 situation occurs when creating shared libraries and symbol
3821 visibility changes render the symbol local.

3824 may need to keep relocations for symbols satisfied by a
3825 dynamic library if we manage to avoid copy relocs for the
