| // 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. |
