@llvm/pr-subscribers-lldb Author: Jacob Lalonde (Jlalond) ChangesThe motivation for this patch is that in Statistics.cpp we check to see if the module symfile is loaded to calculate how much debug info has been loaded. I have an external utility that only wants to look at the loaded debug info, which isn't exposed by the SBAPI. Full diff: https://github.com/llvm/llvm-project/pull/134163.diff 2 Files Affected:
