    [builtins] Introduce proper Float64Exp operator. · d5f2ac5e
    bmeurer authored
    Import base::ieee754::exp() from FreeBSD msun and introduce a Float64Exp
    TurboFan operator based on that, similar to what we do for Float64Log.
    Rewrite Math.exp() as TurboFan builtin and use that operator to also
    inline Math.exp() into optimized TurboFan functions.
