+@table @gcctabopt
+
+@item -march=@var{cpu-type}
+@opindex march
+Generate code that will run on @var{cpu-type}, which is the name of a system
+representing a certain processor type. Possible values for
+@var{cpu-type} are @samp{MS1-64-001}, @samp{MS1-16-002}, and
+@samp{MS1-16-003}.
+
+When this option is not used, the default is @option{-march=MS1-16-003}.

+
+@item -mno-mul
+@opindex mno-mul
+Do not generate multiply instructions.

+@item -mbacc
+@opindex mbacc
+Use byte loads and stores when generating code.
+
+@item -mno-bacc
+@opindex mno-bacc
+Do not use byte loads and stores when generating code.
+
+@item -msim
+@opindex msim
+Use simulator runtime
+
+@item -mno-crt0
+@opindex mno-crt0
+Do not link in the C run-time initialization object file
