[cfe-dev] Windows and Clang

Thu Sep 3 03:16:26 PDT 2015

I'm using Visual Studio 2013 (just because we suppose it'll be better
tested etc) with revision 245761 of clang, compiler-rt and llvm. I'm also
using the ORC JIT engine to compile the C++ code.

The errors we're getting are non-deterministic, which is what is making it
so hard to figure out.

Are you building the release from source, and if so, what cmake flags are
you using? Any other things I should know about that you use to build your
project?

Much appreciated as always,

Joshua
