* rtl.h (enum reg_note): Likewise.
* config/ia64/ia64-protos.h (emit_safe_across_calls): Renamed from
ia64_file_start.
* config/ia64/ia64.c (emit_safe_across_calls): Likewise.
(rtx_needs_barrier): Handle unspec_volatile 8 and 9.
(emit_predicate_relation_info): Handle conditional calls with
REG_NORETURN.
* config/ia64/ia64.h (ASM_FILE_START): Call emit_safe_across_calls
