475895 - Round-trip change with multiple ternary operator uses

Status: RESOLVED WORKSFORME

(Core :: JavaScript Engine, defect)

Description

[Jesse Ruderman]

js> f = function(a) { return (a ? 2 : 3) ? 4 : 5; }
function (a) {
    return a ? 2 : 3 ? 4 : 5;
}

js> eval(uneval(f))
function (a) {
    return a ? 2 : 4;
}

Similarly, "(a ? 2 : x) ? 4 : 5" is given different bytecode than "a ? 2 : x ? 4 : 5", although in that case both decompile the same way.
