for  gcc/ChangeLog
from  Alexandre Oliva  <aoliva@redhat.com>

	* tree-pretty-print.c (dump_function_header): Add flags.
	Don't dump decl_uid with nouid.
	* tree-pretty-print.h (dump_function_header): Adjust.
	* final.c (rest_of_clean_state): Pass dump_flags on, with nouid.
	* passes.c (pass_init_dump_file): Pass dump_flags on.
	* tree-cfg.c (gimple_dump_cfg): Pass flags on.
