{color:#1d1c1d}In gandiva, when we have nested if-else statements we reuse the
local bitmap and treat it is a single logical if - elseif - .. - --else
condition. However, when he have say another function between them like{color}
{color:#1d1c1d}IF{color}
{color:#1d1c1d}THEN{color}
{color:#1d1c1d}ELSE{color}
{color:#1d1c1d}function({color}
{color:#1d1c1d}IF{color}
{color:#1d1c1d}THEN{color}
{color:#1d1c1d}ELSE{color}
{color:#1d1c1d}){color}
{color:#1d1c1d}in such cases also currently we are doing same thing which can
lead to incorrect results{color}
