// 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
|
