1023 We initially store MY_PLT_INDEX in the high bits so that we can use the all
1024 16 bits as an unsigned offset; if we use the low bits we would get an
1025 unwanted sign extension. The PLT header then rotates the index to get the
1026 right value, before calling the resolution routine. This computation can
1027 fit in unused bundle slots so it's free.
1029 This code sequence lets the code at at the start of the PLT determine
1030 which PLT entry was executed by examining 'r29'.
1032 Note that MY_PLT_INDEX skips over the header entries, so the first
1033 actual jump table entry has index zero.

2623 The RELOCATE_SECTION function is called by the new ELF backend linker
2624 to handle the relocations for a section.
2626 The relocs are always passed as Rela structures.
2628 This function is responsible for adjusting the section contents as
2629 necessary, and (if generating a relocatable output file) adjusting
2630 the reloc addend as necessary.
2632 This function does not have to worry about setting the reloc
2633 address or the reloc symbol index.
2635 LOCAL_SYMS is a pointer to the swapped in local symbols.
2637 LOCAL_SECTIONS is an array giving the section in the input file
2638 corresponding to the st_shndx field of each local symbol.
2640 The global hash table entry for the global symbols can be found
2641 via elf_sym_hashes (input_bfd).
2643 When generating relocatable output, this function must handle
2644 STB_LOCAL/STT_SECTION symbols specially. The output symbol is
2645 going to be the section symbol corresponding to the output
2646 section, which means that the addend must be adjusted
