title: what's .rela.plt section in executable object files?
body: <p>I use static linking to produce the executable object files and I use <code>readelf</code> to check the file and found there is one section called:  <code>.rela.plt </code></p>
  <p>the keyword 'rela' indicates that this is related to relocation. but since I use  static linking, not using any shared library, so the output executable file should be a fully linked executable file, so why this file still contain relocation information?</p>
