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.
