10 /// A single function which is called to drive the opt behavior for the new
11 /// PassManager.
12 ///
13 /// This is only in a separate TU with a header to avoid including all of the
14 /// old pass manager headers and the new pass manager headers into the same
15 /// file. Eventually all of the routines here will get folded back into
16 /// opt.cpp.
