Even if the actual publishing of the progress event was free, there's still appears to be quite a bit of code executed before we reach that point. For example, the "if sending progress" block in `UpdateImportProgress` is 15 lines long, it definitely looks like it can end up allocating memory, etc. https://github.com/llvm/llvm-project/pull/91452 _______________________________________________ lldb-commits mailing list lldb-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits
