2011-12-19 Richard Guenther <rguenther@suse.de>
PR lto/51573
* streamer-hooks.h (struct streamer_hooks): Add second
ref_p parameter to write_tree.
(stream_write_tree): Adjust.
(stream_write_tree_shallow_non_ref): New define.
* lto-streamer.h (lto_output_tree): Adjust.
* lto-streamer-out.c (lto_output_tree): Likewise.
* tree-streamer-out.c (streamer_write_chain): Only
force the immediate tree to be streamed as non-reference.
* gcc.dg/lto/20111207-2_0.c: Adjust.
