A while ago llvm-cov gained support for clang's instrumentation based profiling in addition to its gcov support, and subcommands were added to choose which behaviour to use. When no subcommand was specified, we fell back to gcov compatibility with a warning that a subcommand would be required in the future. Now, we require the subcommand. Note that if the basename of llvm-cov is gcov (via symlink or hardlink, for example), we still use the gcov compatible behaviour with no subcommand required. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@233132 91177308-0d34-0410-b5e6-96231b3b80d8
