Initially I was thinking that we can pass any shell output to the caller so either module cache or ELF ObjectFile will verify its correctness - but since Platform::GetFile can be used to download an arbitrary file we should try to handle execution errors as much as we can. I added for "/system/bin/sh:" output prefix check - presumably it should cover majority of failures. As an alternative we can run a command like "$user_cmd || echo $rand_id" and then look whether output ends with $rand_id - but it might be an overkill. http://reviews.llvm.org/D22081 _______________________________________________ lldb-commits mailing list lldb-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits
