	* cgraphunit.c (cgraph_finalize_compilation_unit): Add a newline
	at the end of a diagnostics message.

	* alloc-pool.c (pool_free): Postpone clearing the pool entry
	until after asserting that it was allocated in the right pool.

	* cfgrtl.c (print_rtl_with_bb): Print predecessor and
	successor edge information as well.  Make output of live regs
	on exit consistent with live regs on entry.
