cse.c (cse_end_of_basic_block): Make static. 

2004-02-18  Paolo Bonzini <bonzini@gnu.org>

	* cse.c (cse_end_of_basic_block): Make static.
	* local-alloc.c (function_invariant_p): Move to
	reload1.c.
	* loop.c (libcall_other_reg, record_excess_regs):
	Make static.
	* reload1.c (function_invariant_p): Moved here
	from local-alloc.c, made static.
	* rtl.h (cse_end_of_basic_block, function_invariant_p,
	libcall_other_reg, record_excess_regs): Remove
	declarations.
