Hi,
This patch exposes several interfaces in tree-ssa-address.c so that they can be used
in cost computation for address iv_use.

Is it OK?

Thanks,
bin

	* tree-ssa-address.c (struct mem_address): Move to header file.
	(valid_mem_ref_p, move_fixed_address_to_symbol): Make it global.
	* tree-ssa-address.h (struct mem_address): Move from C file.
	(valid_mem_ref_p, move_fixed_address_to_symbol): Declare.
