<div><span></span>Hi, everyone.</div>
<div>I am a fresh man in the field of compiler.</div>
<div><br>
</div>
<div>I find the implementation of the register allocator based on graph coloring in LLVM 1.0.</div>
<div>However, it is removed in the current release, maybe 3.9 or 3.9.1, i am not absolutely sure.</div>
<div>So is there a plan to add it back in the future version?</div>
