 //
-// These passes are used to cleanup the output of GCC.  GCC's output is
-// unneccessarily gross for a couple of reasons. This pass does the following
-// things to try to clean it up:
-//
-// * Eliminate names for GCC types that we know can't be needed by the user.
-// * Eliminate names for types that are unused in the entire translation unit
-// * Fix various problems that we might have in PHI nodes and casts
-// * Link uses of 'void %foo(...)' to 'void %foo(sometypes)'
-//
-// Note:  This code produces dead declarations, it is a good idea to run DCE
-//        after this pass.
