1040 16 bits as an unsigned offset; if we use the low bits we would get an
1041 unwanted sign extension. The PLT header then rotates the index to get the
1042 right value, before calling the resolution routine. This computation can
1043 fit in unused bundle slots so it's free.
1045 This code sequence lets the code at at the start of the PLT determine
1046 which PLT entry was executed by examining 'r29'.
1048 Note that MY_PLT_INDEX skips over the header entries, so the first
1049 actual jump table entry has index zero.
