Well, or just use some default name of the unit ;)

Interestingly, LTO actually tries to use the original file name:

  /* Since SET does not need to be processed by LTRANS, use
 the original file name and mark it with a '*' prefix so that
 lto_execute_ltrans knows not to process it.  */
  cgraph_node_set_iterator si = csi_start (set);
  struct cgraph_node *first = csi_node (si);
  fname = prefix_name_with_star (first->local.lto_file_data->file_name);

But it tries to take the file name from the first node in the call graph. And
the reason why we try re-use the original file name, is because the call graph
is empty. Strange logic...

Maybe WHOPR should give a fatal error if the only set is empty.

Same happens with

cat >a.c <<\EOF
int i = 42;
EOF

or with

cat >a.c <<\EOF
int foo;
int *i = &foo;
EOF
