</div>What is the common use case? Making sure some funtion is always<br>
optimized or making sure it never optimized? If the second one, I<br>
wonder if marking it cold would be a good enough approximation.<br>
<br>
If we do need to enabled/disable passes run in each function, I would<br>
suggest starting by proposing which attributes should be added to the<br>
language reference.</blockquote><div><br></div><div style>Wasn't this already proposed?</div><div style><a href="http://lists.cs.uiuc.edu/pipermail/llvmdev/2013-January/058112.html">http://lists.cs.uiuc.edu/pipermail/llvmdev/2013-January/058112.html</a><br>
