1011 jr r27

1013
1014 Subsequent entries are the following, jumping to the header at the end:
1015
1016 lnk r28
10171:
1018 {
1019 auli r28, r28, <_GLOBAL_OFFSET_TABLE_ - 1b + MY_GOT_OFFSET>
1020 auli r27, r28, <_GLOBAL_OFFSET_TABLE_ - 1b>

1035 We initially store MY_PLT_INDEX in the high bits so that we can use the all
1036 16 bits as an unsigned offset; if we use the low bits we would get an
1037 unwanted sign extension. The PLT header then rotates the index to get the
1038 right value, before calling the resolution routine. This computation can
1039 fit in unused bundle slots so it's free.
1040
1041 This code sequence lets the code at at the start of the PLT determine
1042 which PLT entry was executed by examining 'r29'.
1043
1044 Note that MY_PLT_INDEX skips over the header entries, so the first
1045 actual jump table entry has index zero.

2770 The RELOCATE_SECTION function is called by the new ELF backend linker
2771 to handle the relocations for a section.
2772
2773 The relocs are always passed as Rela structures.
2774
2775 This function is responsible for adjusting the section contents as
2776 necessary, and (if generating a relocatable output file) adjusting
2777 the reloc addend as necessary.
2778
2779 This function does not have to worry about setting the reloc
2780 address or the reloc symbol index.
2781
2782 LOCAL_SYMS is a pointer to the swapped in local symbols.
2783
2784 LOCAL_SECTIONS is an array giving the section in the input file
2785 corresponding to the st_shndx field of each local symbol.
2786
2787 The global hash table entry for the global symbols can be found
2788 via elf_sym_hashes (input_bfd).
2789
2790 When generating relocatable output, this function must handle
2791 STB_LOCAL/STT_SECTION symbols specially. The output symbol is
2792 going to be the section symbol corresponding to the output
2793 section, which means that the addend must be adjusted
2794 accordingly. */
