+// 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.
