+
+@c man begin OPTIONS
+@table @gcctabopt
+@cindex @code{-mtune=@var{arch}} command line option, Visium
+@item -mtune=@var{arch}
+This option specifies the target architecture. If an attempt is made to
+assemble an instruction that will not execute on the target architecture,
+the assembler will issue an error message.
+
+The following names are recognized:
+@code{mcm24}

+@subsection Special Characters
+
+@cindex line comment character, Visium
+@cindex Visium line comment character
+Line comments are introduced either by the @samp{!} character or by the
+@samp{;} character appearing anywhere on a line.
+
+A hash character (@samp{#}) as the first character on a line also
+marks the start of a line comment, but in this case it could also be a
+logical line number directive (@pxref{Comments}) or a preprocessor
+control command (@pxref{Preprocessing}).
+
+@cindex line separator, Visium
+@cindex statement separator, Visium
+@cindex Visium line separator
+The Visium assembler does not currently support a line separator character.
+
+@node Visium Registers
+@subsection Register Names
+@cindex Visium registers
+@cindex register names, Visium
+Registers can be specified either by using their canonical mnemonic names
+or by using their alias if they have one, for example @samp{sp}.
+
+@node Visium Opcodes
+@section Opcodes
+All the standard opcodes of the architecture are implemented, along with the
+following three pseudo-instructions: @code{cmp}, @code{cmpc}, @code{move}.
+
+In addition, the following two illegal opcodes are implemented and used by the simulation:
+
+@example
+stop 5-bit immediate, SourceA
+trace 5-bit immediate, SourceA
+@end example
