Avoid streaming stray references.
this patch avoids stremaing completely useless stray references to gobal decl
stream. I am re-testing the patch (rebased to current tree) on x86_64-linux
and intend to commit once testing finishes.
gcc/ChangeLog:
2020-05-22 Jan Hubicka <hubicka@ucw.cz>
* lto-streamer-out.c (lto_output_tree): Do not stream final ref if
it is not needed.
gcc/lto/ChangeLog:
2020-05-22 Jan Hubicka <hubicka@ucw.cz>
* lto-common.c (lto_read_decls): Do not skip stray refs.
