similar to: Unit tests in compiler-rt not rebuilding with changes to runtimes?

Hi Dean, For me the build is still broken: -- Builtin supported architectures: i386;x86_64;x86_64h CMake Error at projects/compiler-rt/lib/xray/tests/CMakeLists.txt:21 (add_library): add_library cannot create target "RTXRay.test.osx" because another target with the same name already exists. The existing target is a static library created in source directory

Hi Dean, I have fixed the build failure in r329832. In general, do you think it would be possible to perform the task using higher-level functions available from AddCompilerRT.cmake? They were written exactly to avoid such errors. Regards, George > On Apr 11, 2018, at 10:50 AM, George Karpenkov <ekarpenkov at apple.com> wrote: > > Hi Dean, > > For me the build is still

Hi Kostya, Evgenii, and David, Recently I've been making some incremental changes to the XRay runtime implementation in compiler-rt to reduce the reliance on the C++ standard library components that might have external linkage dependencies. This involves not using containers from the STL and not using non-trivially destructible C++11 thread_local objects. I was wondering whether the

# Objective Implement an XRay mode 'xray-profiling' that gathers stack trace latencies/durations and builds histograms to provide basic statistics about where time is going in an execution of the application. # Background XRay has two modes currently implemented in compiler-rt: a basic (nee naive) mode and flight data recorder (FDR) mode. Basic mode logging, when enabled, will collect

Aside: would it be useful to execute a build of the libc++/libc++abi with msan normally during release, and change the driver to look for these msan-built C++ libs when "-fsanitize=memory"? That would drastically cut down on the complexity of using msan. On Fri, Aug 31, 2018 at 5:43 AM Dean Michael Berris via llvm-dev < llvm-dev at lists.llvm.org> wrote: > Thanks Vitaly and

Another option is just to run corresponding script from *https://llvm.org/svn/llvm-project/zorg/trunk/zorg/buildbot/builders/sanitizers/ <https://llvm.org/svn/llvm-project/zorg/trunk/zorg/buildbot/builders/sanitizers/>* in empty directory.

Hi Dean, I have tried with -instr-map-1 and -instr-map-2, it didn't work.

Hi, The call graphs generated by "*llvm-xray graph*" has function names, while the "*llvm-xray graph-diff*" doesn't shows function names. This is the command I am using llvm-xray graph-diff xray-log.clang.1 xray-log.clang.2 -instr-map=../xray-build/bin/clang -o diff.dot Attached is the portion of the generated diff graph. Am I missing any flag? [image: graph_diff.jpg]

Hi llvm-dev, I'm trying to reproduce an msan failure in one of the bots, but I can't seem to get the right incantation of building LLVM with msan. Here's what I've been doing: 1) Build the toolchain in one build directory, including `compiler-rt`. 2) Build the toolchain again with the just built toolchain in step 1, but this time with `-DLLVM_USE_SANITIZER=MemoryWithOrigins`. I

Hi cfe-dev@ and llvm-dev@, I've attached a Chrome trace-viewer readable trace of a clang built with XRay instrumentation (additional build/link flags="-fxray-instrument -fxray-instruction-threshold=75") with the latest "top-of-trunk" version of clang with the recent updates to the XRay runtime supporting record filtering.
