Hi,

To follow up from Paul last week:

I'm expecting to have our internal builds switched over later this week. Our investigations have shown no problems. We've now updated our internal builds from 2012.4 (cl.exe 17.0.61030) to 2013.3 (cl.exe 18.00.30723). Our automated testing over the weekend hasn't shown any correctness issues so we plan to continue using it now.. From some of the stats I've collected it seems to be a worthwhile update. On my own machine, the time for a full rebuild from clean of ALLBUILD (LLVM & Clang, Release + asserts + debug info, not using ninja) has improved by 20%. Doing a like-for-like build of various benchmarks and games using clang built by VS2012 and VS2013, the clang build speed of a typical -O2 -g build is somewhere between in the noise and 1% faster with VS2013. We've not yet observed any regressions in the speed of clang since upgrading.

Great, thank you for the feedback!
