(lto_free_section_data): Likewise. (lto_get_raw_section_data): New function. (lto_free_raw_section_data): New function. (copy_function_or_variable): Copy sections w/o decompressing. (lto_output_decl_state_refs): Picke compressed bit. * lto-streamer.h (lto_in_decl_state): New flag compressed. (lto_out_decl_state): Likewise. (lto_get_section_data, lto_free_section_data): Update prototypes (lto_get_raw_section_data, lto_free_raw_section_data): Declare. (lto_write_raw_data): Declare. (lto_begin_section): Remove FIXME. (lto_write_raw_data): New function. (lto_write_stream): Remove FIXME. (lto_new_out_decl_state): Set compressed flag.
