-@section @code{.cfi_verbose [1|0]}
-Switch on/off verbosity of the CFI machinery. @value{AS} will print
-lots of useful messages to standard output if you use this directive.
+@section @code{.cfi_rel_offset @var{register}, @var{offset}}
+Previous value of @var{register} is saved at offset @var{offset} from
+the current CFA register. This is transformed to @code{.cfi_offset}
+using the known displacement of the CFA register from the CFA.
+This is often easier to use, because the number will match the
+code it's annotating.
