1020 We initially store MY_PLT_INDEX in the high bits so that we can use the all
1021 16 bits as an unsigned offset; if we use the low bits we would get an
1022 unwanted sign extension. The PLT header then rotates the index to get the
1023 right value, before calling the resolution routine. This computation can
1024 fit in unused bundle slots so it's free.
1025
1026 This code sequence lets the code at at the start of the PLT determine
1027 which PLT entry was executed by examining 'r29'.
1028
1029 Note that MY_PLT_INDEX skips over the header entries, so the first
1030 actual jump table entry has index zero.

1677 against a global symbol, or a non PC relative reloc
1678 against a local symbol, then we need to copy the reloc
1679 into the shared library. However, if we are linking with
1680 -Bsymbolic, we do not need to copy a reloc against a
1681 global symbol which is defined in an object we are
1682 including in the link (i.e., DEF_REGULAR is set). At
1683 this point we have not seen all the input files, so it is
1684 possible that DEF_REGULAR is not set now but will be set
1685 later (it is never cleared). In case of a weak definition,
1686 DEF_REGULAR may be cleared later by a strong definition in
1687 a shared library. We account for that possibility below by
1688 storing information in the relocs_copied field of the hash
1689 table entry. A similar situation occurs when creating
1690 shared libraries and symbol visibility changes render the
1691 symbol local.
1692
1693 If on the other hand, we are creating an executable, we
1694 may need to keep relocations for symbols satisfied by a
1695 dynamic library if we manage to avoid copy relocs for the
