	gcc            : ChangeLog tree-data-ref.c 

Log message:
	* tree-data-ref.c (find_data_references_in_loop): Give up when
	the body of the loop contains a CALL_EXPR or an ASM_EXPR: they
	may embed arbitrary side effects.
	Remove the assumption that GIMPLE form contains a single array
	access per statement.
	When the statement contains virtual operands, fail if it is not
	a MODIFY_EXPR or a CALL_EXPR.
	Return after the dont know node is inserted.
