Split out LTO's writing of top level asm nodes in preparation of extending
what needs to be written out when top level asm-s get enhanced to accept a limited set of input operands. gcc/ 2011-09-30 Jan Beulich <jbeulich@suse.com> * lto-cgraph.c (output_cgraph): Remove processing of 'cgraph_asm_nodes', call lto_output_toplevel_asms() instead. (input_cgraph_1): Remove loop calling cgraph_add_asm_node(), call lto_input_toplevel_asms() instead. * lto-section-in.c (lto_section_name): Add "asm" entry. * lto-streamer-in.c (lto_input_toplevel_asms): New. * lto-streamer-out.c (lto_output_toplevel_asms): New. * lto-streamer.h (LTO_minor_version): Bump. (enum lto_section_type): Add LTO_section_asm. (struct lto_asm_header): New. (lto_input_toplevel_asms, lto_output_toplevel_asms): Declare. * tree-streamer.h (streamer_write_string_cst): Declare. * tree-streamer-out.c (write_string_cst): Rename to streamer_write_string_cst and make global. Handle incoming string being NULL. (streamer_write_tree_header): Adjust call to renamed function. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@179386 138bc75d-0d04-0410-961f-82ee72b054a4
