Situations in which 'else' or 'elsif' are unnecessary.

Hello.

signal slv : std_logic_vector(1 downto 0);
signal s1,s2 : std_logic;
process()
begin
  s1 <= '0';
  s2 <= '0';
-----------------
--
-- Version with 'elsif'
--
  if(slv = "00") then
    s1 = '1';
  elsif (slv = "10") then
    s2 = '1';
  end if;
-----------------
--
-- Version without 'elsif'
--
  if (slv = "00") then
    s1 <= '1';
  end if;
  if (slv = "10") then
    s2 <= '1';
  end if;
-----------------
end process;

Any difference?
