// 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. In the ARM case irelative relocations do not count as PLT
|
|
// relocs.
