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

3862 including in the link (i.e., DEF_REGULAR is set). At

3865 later (it is never cleared). We account for that
3866 possibility below by storing information in the
3867 dyn_relocs field of the hash table entry. A similar
3868 situation occurs when creating shared libraries and symbol
3869 visibility changes render the symbol local.
