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

45/// \brief Driver function to run the new pass manager over a module.
46///
47/// This function only exists factored away from opt.cpp in order to prevent
48/// inclusion of the new pass manager headers and the old headers into the same
49/// file. It's interface is consequentially somewhat ad-hoc, but will go away
50/// when the transition finishes.
