+// The -time option prints timing information for the various subcommands in a
+// format similar to that used by gcc. When compiling and linking, this will
+// include the time to call clang-${LLVM_VERSION_MAJOR} and the linker. Since

+// could be something different, just check that whatever is printed to stderr
+// looks like timing information.
