[PATCH] Fix passing double float complex arguments in sparc64

Thank you. I don't think one way is all that better than the other
(I actually find this way a little confusing at first), but I prefer
that everything remains consistent...

The patch is OK. Watch out for the 'n' at the start of the date in
this ChangeLog entry.

Just one tiny formatting request before committing:

> +	  /* Float Complex or double Complex arguments.  */
> +	  if (element < 16)
> +	    {
> +	      regnum = SPARC64_D0_REGNUM + element;
> +	      
> +	      if (len == 16)

Can you remove the tabs/spaces in the empty line before the "if"?

Thank you,
