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