The presence of a 'trunc' in the conditional basic block shouldn't be the thing that enables or disables this. All I wanted out of this patch was improved stability and consistency on x86.</div></blockquote><br>

<div style><br></div><div style><br></div><div style>Clearly this commit is more controversial than I had ever anticipated (including when I mentioned it to Chris on IRC), so I'm happy to back it out... It'll be a bit, as I can't just revert it at this point -- there were other patches here that fixed somewhat serious bugs -- but I'll get to it soon.</div>
<div style><br></div><div style><br></div><div style>Anyways, I think there is a lot of confusion, miscommunication, and misunderstanding in this thread (and the other on a related subject, but which had *nothing* to do with my actual commits)... So I hope we can get back to discussing the actual technical issues at hand here. Note that while I've reverted this patch, SimplifyCFG still uses TTI, and fixing that is a bigger task -- that was introduced with the lookup table optimization.</div>
