1012 | We initially store MY_PLT_INDEX in the high bits so that we can use the all | |
1013 | 16 bits as an unsigned offset; if we use the low bits we would get an | |
1014 | unwanted sign extension. The PLT header then rotates the index to get the | |
1015 | right value, before calling the resolution routine. This computation can | |
1016 | fit in unused bundle slots so it's free. | |
1017 | ||
1018 | This code sequence lets the code at at the start of the PLT determine | |
1019 | which PLT entry was executed by examining 'r29'. | |
1020 | ||
1021 | Note that MY_PLT_INDEX skips over the header entries, so the first | |
1022 | actual jump table entry has index zero. | |
