这样的告别有点早，但是随着 IonMonkey 正式在 Firefox 18 中启用，JaegerMonkey 的替换工作也会开始加速。从 Mozilla Bugzilla 中的这个页面（Bug 805241）可以看到相关的工作已经进行了大半，JaegerMonkey 被一个简单的 Baseline Compiler 替换掉的日子或许已经不远了。贴上 Baseline Compiler 的目标：

Now that IonMonkey has landed, we want to replace JM(+TI) with a much simpler baseline compiler. The main goals are

* No dependency on TI, no recompilations caused by type changes * Fast compilation times * Clean design, easy to support new ops * No advanced optimizations (LICM, inlining, regalloc) * ICs for most operations, reusable IC stubs * Collect and store data useful for Ion compilation
