You don't actually need to create a target for this. Something like: ``` spec = lldb.SBModuleSpec() spec.SetFileSpec(self.getBuildArtifact(filename)) lldb.SBModule(spec).GetUUIDString() ``` ought to suffice. ``` https://github.com/llvm/llvm-project/pull/90622 _______________________________________________ lldb-commits mailing list lldb-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits
