| // The linker script above combines the .rela.dyn and .rela.plt into a single |
| // table. ELF is clear that the DT_PLTRELSZ should match the subset of |
| // relocations that is associated with the PLT. It is less clear about what |
| // the value of DT_RELASZ should be. ELF implies that it should be the size |
| // of the single table so that DT_RELASZ includes DT_PLTRELSZ. The loader in |
| // glibc permits this as long as .rela.plt comes after .rela.dyn in the |
| // combined table. In the ARM case irelative relocations do not count as PLT |
| // relocs. In the AArch64 case irelative relocations count as PLT relocs. |
