<p>Does anyone have experience with <a href="http://llvm.org/" rel="nofollow noreferrer"><strong>LLVM</strong></a>, <a href="http://dragonegg.llvm.org/" rel="nofollow noreferrer"><strong>llvm-gcc</strong></a>, or <a href="http://clang.llvm.org/" rel="nofollow noreferrer"><strong>Clang</strong></a>?</p>

<p>The whole idea behind llvm seems very intriguing to me and I'm interested in seeing how it performs.  I just don't want to dump a whole lot of time into trying the tools out if the tools are not ready for production.</p>

<p>If you have experience with the tools, what do you think of them?  What major limitations have you encountered?  What are the greatest benefits?</p>

<p>Many thanks!</p>

I've had an initial play around with LLVM and working through
this tutorial
left me very very excited about it's potential; the idea that I can use it to build a JIT into an app with relative ease has me stoked.
I haven't gone deep enough to be able to offer any kind of useful opinion on it's limitations, stability, performance and suchlike. I understand that it's good on all counts but that's purely hearsay.
