  18 ## Simple test built from this input which produces DWARF long enough to be compressed in the .[z]debug_info section:
  19 ##
  20 ##   void f(int a, int b, int c, int d) {
  21 ##   }
  22
  23 ## Since the compression is pretty orthogonal, we're not trying to test that the
  24 ## compression library functioned correctly, just that dwp used it to decompress
  25 ## the section - so test a few simple features and be done with it.
