Hi llvm-dev, I've been implementing a tool for analysing XRay traces. A recap of XRay's original RFC [0] mentions a tool that does function call accounting as a starting point. This is implemented currently in D21987 [1], and is being reviewed by David Blaikie. One key issue in that review is the dependency between the log format determined by the XRay runtime implementation in

Hi Dean, I have tried with -instr-map-1 and -instr-map-2, it didn't work. Is there a way to find the function name from the identifier? -DTharun On Mon, Jan 7, 2019 at 2:29 PM Dean Michael Berris <dean.berris at gmail.com> wrote: > Hi Dangeti, > > That's interesting -- can you try providing both `-instr-map-1=` and > `-instr-map-2=` even though they're the same

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.

Hi llvm-dev, I have unit tests set up in the XRay implementation (compiler-rt/lib/xray/tests/unit) following the pattern that the TSAN and other sanitiser unit tests. However, I'm running into the following problem: When I make changes to the runtime (in this case, XRay) and do `ninja all check-xray`, it seems that the unit tests don't get re-liked to the new version of the runtime. It

Hi Dean, Do you have any estimates on when https://reviews.llvm.org/D21982 will reach mainline? (As I understood it's not yet there, looking at http://llvm.org/svn/llvm-project/compiler-rt/trunk ). I would like to test ARM port of XRay, so ready logging would be handful. Thanks, Serge On 8 August 2016 at 17:41, Dean Michael Berris <dean.berris at gmail.com> wrote: > > > On 8

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

I'm still somewhat unclear about what you mean by "metadata record entry at the beginning of the block". I understand that I can make a MetadataRecord that contains the pid/tid since a metadata record contains 16 bytes. However, I don't understand what do you mean by the "beginning of the block". Do you mean right after the file header? My understanding is that at
