1012 We initially store MY_PLT_INDEX in the high bits so that we can use the all
1013 16 bits as an unsigned offset; if we use the low bits we would get an
1014 unwanted sign extension. The PLT header then rotates the index to get the
1015 right value, before calling the resolution routine. This computation can
1016 fit in unused bundle slots so it's free.
1017
1018 This code sequence lets the code at at the start of the PLT determine
1019 which PLT entry was executed by examining 'r29'.
1020
1021 Note that MY_PLT_INDEX skips over the header entries, so the first
1022 actual jump table entry has index zero.

2487
2488 The RELOCATE_SECTION function is called by the new ELF backend linker
2489 to handle the relocations for a section.
2490
2491 The relocs are always passed as Rela structures.
2492
2493 This function is responsible for adjusting the section contents as
2494 necessary, and (if generating a relocatable output file) adjusting
2495 the reloc addend as necessary.
2496
2497 This function does not have to worry about setting the reloc
2498 address or the reloc symbol index.
2499
2500 LOCAL_SYMS is a pointer to the swapped in local symbols.
2501
2502 LOCAL_SECTIONS is an array giving the section in the input file
2503 corresponding to the st_shndx field of each local symbol.
2504
2505 The global hash table entry for the global symbols can be found
2506 via elf_sym_hashes (input_bfd).
2507
2508 When generating relocatable output, this function must handle
2509 STB_LOCAL/STT_SECTION symbols specially. The output symbol is
2510 going to be the section symbol corresponding to the output
2511 section, which means that the addend must be adjusted
2512 accordingly. */
