Hi,<div><br></div><div>I am working on upgrading our compiler backend from llvm 2.8 to 3.0/3.1. I have been reading the release docs, llvm blogs etc that talk about the type system rewrite, exception handling rewrite, new register allocators etc to know the changes. One of our major concerns is that even though our compiler's run time has boosted a lot, thanks to llvm, our compile time is pretty high. I searched for info related to compile time and run time improvements for the releases but couldn't find one. It would be great if one could point me out to these docs, if any.</div>
