@ -303,6 +303,10 @@ Various V9 branch and conditional move instructions allow
specification of which set of integer condition codes to
test. These are referred to as @samp{%xcc} and @samp{%icc}.
Additionally, GAS supports the so-called ``natural'' condition codes;
these are referred to as @samp{%ncc} and reference to @samp{%icc} if
the word size is 32, @samp{%xcc} if the word size is 64.
In V9, there are 4 sets of floating point condition codes
which are referred to as @samp{%fcc@var{n}}.
