	gcc            : ChangeLog tree-into-ssa.c 

Log message:
	* tree-into-ssa.c (ssa_rewrite_initialize_block): Do not register
	definitions of SSA_NAMEs which are not being rewritten.
	(rewrite_ssa_into_ssa): Only initialize the current definition
	of an SSA_NAME if that SSA_NAME has been marked for rewriting.
	If checking is enabled, assert that SSA_NAME_AUX is clear for all
	SSA_NAMEs before returning.
