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.
