re PR lto/47788 (New LTO failures)
2012-10-04 Richard Guenther <rguenther@suse.de>
PR lto/47788
* tree-streamer-out.c (write_ts_block_tree_pointers): For
inlined functions outer scopes write the ultimate origin
as BLOCK_ABSTRACT_ORIGIN and BLOCK_SOURCE_LOCATION.
Do not stream the fragment chains.
* tree-streamer-in.c (lto_input_ts_block_tree_pointers): Likewise.
* dwarf2out.c (gen_subprogram_die): Handle NULL DECL_INITIAL.
(dwarf2out_decl): Always output DECL_ABSTRACT function decls.
