      Force setproctitle() into .init_array section · 6faea4d2
      Guillem Jover authored
      The GNU .init_array support is an extension over the standard System V
      ABI .init_array support, which passes the main() arguments to the init
      function.
      
      This support comes in three parts. First the dynamic linker (from glibc)
      needs to support it. Then function pointers need to be placed in the
      section, for example by using __attribute__((constructor)), that the
      compiler (gcc or clang for example) might place in section .ctors and
      the linker (from binutils) will move to .init_array on the output
      object, or by placing them directly into .init_array by the compiler
      when compiling. If this does not happen and the function pointers end
      up in .ctors, then they will not get passed the main() arguments, which
      we do really need in this case.
      
      But this relies on recent binutils or gcc having native .init_array
      support, and not having it disabled through --disable-initfini-array.
      
      To guarantee we get the correct behaviour, let's just place the function
      pointer in the .init_array section directly, so we only require a recent
      enough glibc.
