+@subsection ARC Options
+@cindex ARC Options
+
+These options are defined for ARC implementations:
+
+@table @code
+@item -EL
+Compile code for little endian mode.  This is the default.
+
+@item -EB
+Compile code for big endian mode.
+
+@item -mmangle-cpu
+Prepend the name of the cpu to all public symbol names.
+In multiple-processor systems, there are many ARC variants with different
+instruction and register set characteristics.  This flag prevents code
+compiled for one cpu to be linked with code compiled for another.
+No facility exists for handling variants that are "almost identical".
+This is an all or nothing option.
+
+@item -mcpu=@var{cpu}
+Compile code for ARC variant @var{cpu}.
+Which variants are supported depend on the configuration.
+All variants support @samp{-mcpu=base}, this is the default.
+
+@item -mtext=@var{text section}
+@item -mdata=@var{data section}
+@item -mrodata=@var{readonly data section}
+Put functions, data, and readonly data in @var{text section},
+@var{data section}, and @var{readonly data section} respectively
+by default.  This can be overridden with the @code{section} attribute.
