Modified files:
	gcc            : ChangeLog.killloop Makefile.in fold-const.c 
	                 tree-flow.h tree-pretty-print.c

Added files:
	gcc            : tree-affine.c tree-affine.h 

Log message:
	* tree-pretty-print.c (dump_bb_header): Fix merge conflict.
	
	* fold-const.c (try_move_mult_to_index): Handle negative multipliers.
	
	* Makefile.in (tree-affine.o): Add.
	(tree-ssa-address.o, tree-ssa-loop-ivopts.o): Add tree-affine.h
	dependency.
	* tree-affine.c: New file.
	* tree-affine.h: New file.
	* tree-flow.h (struct affine_tree_combination): Moved to
	tree-affine.h.
	* tree-ssa-address.c: Include tree-affine.h.
	(fixed_address_object_p): Export.
	(add_to_parts): Do not take coef argument.
	(most_expensive_mult_to_index, addr_to_parts, create_mem_ref):
	Use tree-affine.h utilities.
	* tree-ssa-loop-ivopts.c: Include tree-affine.h.
	(struct iv_use, struct iv_cand): Add base_aff field.
	(record_use, add_candidate_1): Initialize base_aff field.
	(determine_base_object): Handle MULT_EXPR.
	(aff_combination_const, aff_combination_elt, aff_combination_scale,
	aff_combination_add_elt, aff_combination_add,
	tree_to_aff_combination, add_elt_to_tree, unshare_aff_combination,
	aff_combination_to_tree): Moved to tree-affine.c.
	(get_computation_aff): Use tree-affine.h utilities.  Never compute
	result in trees directly.  Return suggested multiplier for an
	addressing mode.
	(get_computation_at, rewrite_use_address): Changed to reflect
	get_computation_aff change.
	(split_address_cost, ptr_difference_cost, difference_cost): Removed.
	(aff_combination_cost, aff_combination_cost_address): New.
	(get_computation_cost_at): Use them.
	* tree.h (fixed_address_object_p): Declare.
