From 65d1b157e98fd9f131bb9021f5d1d29f335ffaa0 Mon Sep 17 00:00:00 2001 From: jbeulich Date: Fri, 30 Sep 2011 14:56:01 +0000 Subject: 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 * 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 --- gcc/lto-cgraph.c | 28 ++++------------------------ 1 file changed, 4 insertions(+), 24 deletions(-) (limited to 'gcc/lto-cgraph.c') diff --git a/gcc/lto-cgraph.c b/gcc/lto-cgraph.c index edc3ad7759e..0f1a8c5ff27 100644 --- a/gcc/lto-cgraph.c +++ b/gcc/lto-cgraph.c @@ -817,7 +817,6 @@ output_cgraph (cgraph_node_set set, varpool_node_set vset) int i, n_nodes; lto_cgraph_encoder_t encoder; lto_varpool_encoder_t varpool_encoder; - struct cgraph_asm_node *can; static bool asm_nodes_output = false; if (flag_wpa) @@ -854,6 +853,8 @@ output_cgraph (cgraph_node_set set, varpool_node_set vset) streamer_write_uhwi_stream (ob->main_stream, 0); + lto_destroy_simple_output_block (ob); + /* Emit toplevel asms.
