The first version of this document is now live: http://llvm.org/docs/Frontend/PerformanceTips.html Please feel free to add to it directly.

Just to be clear, you mean the release notes for 3.7 not 3.6 right? On 03/04/2015 02:15 PM, Hans Wennborg wrote: > This is great.

I'm going to keep the first version short, and then open it for others to contribute. Philip On 02/24/2015 02:13 PM, Sean Silva
