Subject: lto: Keep lto file data
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3facb0e2b5a1a407ad71327ed56cd81109a37b1b;p=thirdparty%2Fgcc.git

lto: Keep lto file data

We use lto_file_data in 1to1 partitioning, so we need to not zero it
out. Nothing depends on lto_file_data being NULL.

gcc/ChangeLog:

	* cgraph.cc (cgraph_node::release_body): Keep lto_file_data.
	(cgraph_node::remove): likewise.
	* lto-section-in.cc (lto_free_function_in_decl_state_for_node):
	likewise.
	* varpool.cc (varpool_node::remove): likewise.

gcc/lto/ChangeLog:

	* lto-symtab.cc (lto_symtab_merge_symbols_1): likewise.
