Hi all, I recently gave LLD a try and it definitely works fine. However one cannot build it together with LLVM_LINK_LLVM_DYLIB: ELF/Driver.cpp and ELF/DriverUtils.cpp pull in llvm/Support/CommandLine.h which defines the command line options so these global variables end up in libLLVM-4.0svn.so via liblldELF. If this shared library is then linked into bin/lld or bin/opt one gets errors because of

It builds fine but I cannot execute the resulting binary which aborts with the mentioned error.However I don't use LLVM_ENABLE_PROJECTS, I don't know if that changes the way libLLVM-4.0svn.so is linked...

I've dealt with similar issues on the LLDB side, I think I can help you with this. pl On 6 January 2017 at 09:39, Rui Ueyama via llvm-dev <llvm-dev at lists.llvm.org> wrote: > Thanks for the info.

Please have a look at the dedicated mailing list: http://lists.llvm.org/pipermail/llvm-branch-commits/ Please wait for the official release to happen, you will then find tarballs on llvm.org. They will also contain correct version strings, though I haven't yet tried building from the SVN branches directly. Maybe you need to use the SVN tags, $ clang --version currently gives me "clang

Hello, I have a problem with my Samba4 AD-Controller and NFS. We want to distribute a NFS-Share for our home directory. The problem is that the client is trying to create it on the fly for the first user login but you get 'Permission denied' because of the root_spuash option of the NFS-Server. My question: Is there any posibillity that the normal home directory is created after adding

Hi Tom, [1] does not list any 3.9.1rc2 pre-release tarballs, can you please upload? Thanks in advance. Regards, - Sedat - [1] http://www.llvm.org/pre-releases/

The source tarball for clang-tools-extra-3.9.0.src.tar.xz is also missing as well from http://llvm.org/releases/3.8.1/.

Dear Colleagues, we have a Samba4 DC in our environment. We are storing unix Information in samba's AD. Our Problem is: The default values are not fitting for our environment. We want to store a different Shell e.g /bin/tcsh. But the default Value is /bin/sh. Is it possible, to change those default values so that it fits direct at the creation of a user? Regards and thanks Daniel --

i have already seen usage of __builtin_nontemporal_store but i want to automate identification of non temporal loads/stores. i think i need to go for a pass. is it possiblee to detect non temporal loops without polly?

Actually i am working on vector accelerator which will perform those instructions which are non temporal. for instance if i have this loop for(i=0;i<2048;i++) a[i]=b[i]+c[i]; currently it emits following IR; %0 = getelementptr inbounds [2048 x i32], [2048 x i32]* @b, i64 0, i64 %index %1 = bitcast i32* %0 to <16 x i32>* %wide.load = load <16 x i32>, <16 x i32>* %1,

Yes, but we don't have anything that does that right now. The cost modeling is non-trivial,

I agree with Tim's assessment for ARM. That's interesting; I wasn't previously aware of that instruction. My understanding is that Alpha would have the same problem for normal loads. I'm all in favor of more systematic handling of the fences associated with x86 non-temporal accesses. AFAICT, nontemporal loads and stores seem to have different fencing rules on x86, none of them
