 Message        <text> instruction used is not in the selected
                instruction set

 Description    The compiler has output an instruction that is not in
                the instruction set selected on the command line.
                One way this can happen is to compile a program which
                contains a floating point operation and specifying
                that no floating point instructions should be
                generated.

 User Action    Either modify the source so the instruction will not
                be necessary, or use a different instruction set.
