-// This file implements stripping symbols out of symbol tables.
-//
-// Specifically, this allows you to strip all of the symbols out of:
-// * All functions in a module
-// * All non-essential symbols in a module (all function symbols + all module
-// scope symbols)
-//
-// Notice that:
-// * This pass makes code much less readable, so it should only be used in
-// situations where the 'strip' utility would be used (such as reducing
-// code size, and making it harder to reverse engineer code).
