Hi,

Attached is a patch to remove all arguments from recompute_reg_usage
as they are not used.

Bootstrapped on i686-pc-linux-gnu.  OK to apply?

	* flow.c (recompute_reg_usage): Remove all arguments.
	* passes.c (rest_of_compilation): Adjust the call to
	recompute_reg_usage.
	* rtl.h: Adjust the prototype for recompute_reg_usage.
