hi everyone, I'm trying to get something like the lli - trace functionality that has been deprecated. I need the same thing that the trace command was doing i. e. the dynamic execution trace, any idea on what it has moved to if it still exists or how to implement it?

...I'm certainly open to this possibility. No concrete plans yet. It's an open question in the original RFC too (http://lists.llvm.org/pipermail/llvm-dev/2016-April/098901.html). There's a white paper that details what we plan to implement out in the open (http://research.google.com/pubs/pub45287.html). We're still working our way to getting to a full version as described in that white paper (basically blocked by my lack of familiarity with the LLVM codebase, and other n00b-y things :D). There's not a concrete list of features, and we're certainly open to contributions from the...

Hi everyone, TL;DR: With current pending patches applied in compiler-rt and llvm, and trunk clang, you can build your application with XRay tracing enabled on Linux with tracing enabled before main starts, and logging stops when the main thread exits. Just a quick update, I have some patches under review that when applied cleanly to LLVM and compiler-rt allows for building applications with XRay
