I just talked to Andrew and we think it's best to change the documentation. How does this sound: """ @item -mabi=@var{ABI-string} @opindex mabi Specify integer and floating-point calling convention. The default for this argument is system dependent, users who want a specific calling convention should specify one explicitly. The valid calling conventions are: ilp32, ilp32f, ilp32d, lp64, lp64f, and lp64d. """
