* lto-symtab.c (lto_symtab_free): New function.
* lto-streamer.h (lto_symtab_free): Declare. * lto-cgraph.c (reachable_from_other_partition_p): Export; do not assume that if function is needed it is reachable. (lto_output_node): See if it the function is reachable or referenced. (output_cgraph): Update call of lto_output_node. * lto-streamer.h (reachable_from_other_partition_p): Declare. * lto.c (lto_fixup_decls): Free no longer needed lto_global_var_decls vector. * lto.c (lto_1_to_1_map): Remove some no longer needed checks. (lto_promote_cross_file_statics): Never promote DECL_EXTERNAL; use reachable_from_other_partition_p and referenced_from_other_partition_p test. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@159280 138bc75d-0d04-0410-961f-82ee72b054a4
