  23 // The goal of this program is to verify if section ordering
  24 // via plugins happens correctly.  Also, test if plugin based ordering
  25 // overrides default text section ordering where ".text.hot" sections
  26 // are grouped.  The plugin does not want foo and baz next to each other.
  27 // Plugin section order is foo() followed by bar() and then baz().
