Hey everyone, I have some weird issue with using multithreaded data.table in macOS and I am trying to figure out, if it?s connected to my libomp.dylib. I started using libomp as stated here: https://mac.r-project.org/openmp/ ? Everything worked fine till beginning of this year, but all of a sudden, I get random fatal errors, when using data.table with multithreading. I figured that R (used in RStudio) is not loading this libomp.dylib (locat...

Hi lists, I am encountering a large number of check-clang failures after building Clang/LLVM with -DLLVM_USE_SANITIZER=Address. I have reported the issue on Bugzilla (https://bugs.llvm.org/show_bug.cgi?id=47678). I cannot even compile helloworld.c with the resulting clang tool without a lot of false positives from ASan. Is it because I am not supposed to use GCC's AddressSanitizer when

Wouldn’t it it be possible to add a flag like the one used in the OpenMP subproject? There they default to linking to the non-functional libgomp (as far as I understand it), and if people want to use the actual libomp runtime, they have to specify -fopenmp=libomp when compiling/linking a program. At the same time, it is possible to use the libomp runtime library by default by specifying -DCLANG_DEFAULT_OPENMP_RUNTIME=libomp at configuration time when building LLVM. That way things would not break for existing...

...hed the logs for the attempt to this message. I installed Perl and the latest version of GCC before that attempt. There were still errors that stopped it from being able to generate project files, though. I'd like to know how I can get this to work. How do I tell it where to find Backtrace, Libomp, Compiler-RT, LLD and Clang? And where exactly is Backtrace? I copy-pasted the locations for the stuff I checked out for LLVM, so I'm not really sure where the stuff I need to put into CMake for Compiler-RT, Backtrace and Libomp is (it's where it should be, that's all I know). ------...
