   M /trunk/gcc/ChangeLog
   M /trunk/gcc/cfgloop.h
   M /trunk/gcc/ipa-pure-const.c
   M /trunk/gcc/tree-ssa-loop-ivcanon.c
   M /trunk/gcc/tree-ssa-loop-niter.c

	* ipa-pure-const.c (struct funct_state_d): New fields
	state_previously_known, looping_previously_known; remove
	state_set_in_source.
	(analyze_function): Use new fields.
	(propagate): Avoid assumption that state_set_in_source imply
	nonlooping.

	* tree-ssa-loop-niter.c (finite_loop_p): New function.
	* tree-ssa-loop-ivcanon.c (empty_loop_p): Use it.
	* cfgloop.h (finite_loop_p): Declare.
