  10 // The linker script above combines the .rela.dyn and .rela.plt into a single
  11 // table. ELF is clear that the DT_PLTRELSZ should match the subset of
  12 // relocations that is associated with the PLT. It is less clear about what
  13 // the value of DT_RELASZ should be. ELF implies that it should be the size
  14 // of the single table so that DT_RELASZ includes DT_PLTRELSZ. The loader in
  15 // glibc permits this as long as .rela.plt comes after .rela.dyn in the
  16 // combined table.
