Dear all, In the official document <https://llvm.org/docs/CompileCudaWithLLVM.html>, it is mentioned that CUDA compilation is supported on Windows as of 2017-01-05. I used msys2 to install clang 5.0.1. Then I installed cuda 8.0. However, I basically could not compile any code of cuda by the prescribed setting. I wounder if anyone can successfully compile cuda code by the clang on Windows.

> Which projects do we put under this monolithic repository? The proposal at the moment is to include llvm, clang, clang-tools-extra, lld, polly, lldb, llgo, compiler-rt, openmp, and parallel-libs. This is the set {llvm} plus the transitive closure of "projects that are version-locked to a project in the set", where the closure is taken over the set of all active LLVM

...64. 2. And I obtain all the necessary files for TX1 by JetPack from the host(X86) and so `nvcc` can work rightly. 3. Althrough I can compile LLVM3.9 on TX1, I can not compile the CUDA program using `clang` tools.

> Today I *can* checkout only LLVM and Clang. On a single Git repo I can't. This is true if you s/checkout/clone/. With a single repo, you must clone (download) everything (*), but after you've done so you can use sparse checkouts to check out (create a working copy of) only llvm and clang. So you should only notice the fact that there exist things other than llvm and clang when you

...truction semantics imposes a much larger burden on the rest of the community. That burden has to be well justified and supported." It is not clear to me right now if the "use case" makes it "well justified" or not (an alternative being using intrinsic for OpenCL as Justin Lebar mentioned). I don’t feel I can answer this, so adding CC Chandler and Sanjoy to begin with. — Mehdi > Mehdi, if things get to the point where you think they're good to go and no one else has chimed in, ping me.

Hi, all. I feel like we've strayed pretty far from the question originally posed in this thread. One of the pieces of feedback I got before I started this thread was that many people felt that, the last time the question of multiple repos vs. monorepo was discussed, it was interspersed with other topics, making it difficult for some people to weigh in appropriately (or even to be aware that
