--- Comment #55 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
 719 #               mbits := '0' & r.mask_size;
 720 #               v.shift := r.shift + (31 - 12) - mbits;
 721 #               nonzero := or(r.addr(61 downto 31) and
 722 #                           not finalmask(30 downto 0));

you can't assign to nonexistent variables.

mbits = Signal(r.mask_size.width+1)
nonzero = Signal()

put those lines just before they are used.

do not add "self." in front of them.  they are local not members of the class.
