	gcc            : ChangeLog.killloop Makefile.in df.c df.h 
	                 loop-invariant.c 

Log message:
	* Makefile.in (loop-invariant.o): Add HASHTAB_H dependency.
	* df.c (df_find_use): New function.
	* df.h (df_find_use): Declare.
	* loop-invariant.c: Include hashtab.h.
	(struct invariant): Replace processed field by reg field.
	Add eqto field.
	(struct invariant_expr_entry): New.
	(df): New global variable.
	(invariant_for_use, hash_invariant_expr_1, invariant_expr_equal_p,
