if a > b THEN
    compare <= "1110";
ELSIF a < b THEN
    compare <= "1101";
ELSIF a = b THEN
    compare <= "1011";
ELSIF ( a >= b ) THEN
    compare <= "0111";
ELSE
    compare <= "1111";
END IF;
The conditions in an IF statements are evaluated in order. The ">=" case in your code will never trigger as in that case either ">" or "=" will always be evaluated first.
