Dear LLVM Community, I am D Tharun Kumar, masters student at Indian Institute of Technology Hyderabad, working in a team to improve current vectorizer in LLVM. As an initial study, we are studying various benchmarks to analyze and compare vectorizing capabilities of LLVM, GCC and ICC. We found that vectorization remarks given by LLV...

So, I've edited /etc/sudoers and added: Cmnd_Alias CMD_MOUNT = /bin/mount Cmnd_Alias CMD_CIFS ) = /sbin/mount.cifs nobody ALL = NOPASSWD: CMD_MOUNT nobody ALL = NOPASSWD: CMD_CIFS But when I run the command as nobody (in the shell), I get the error: "mount
