The formatting is wrong, && shouldn't be at the end of line.
For the rest I'll defer to Jason, not sure what exactly we want to do there.

	* cgraphunit.c (cgraph_create_edges): Do not walk BLOCK; finalize
	local statics when doing unit-at-a-time.
	(cgraph_varpool_assemble_pending_decls): Output debug info.
	* dwarf2out.c (decls_for_scope): Skip local statics.
	(dwarf2out_decl): Handle local statics.
	* passes.c (rest_of_decl_compilation): Do not differentiate
	local and global statics in unit-at-a-time.
	* tree-inline.c (remap_decls): Put local static into
	unexpanded_vars_list rather than introducing duplicated VAR_DECL
	node.
