-// This file defines a pass that can be used to determine, interprocedurally,
-// which pointer types are accessed unsafely in a program.  If there is an
-// "unsafe" access to a specific pointer type, transformations that depend on
-// type safety cannot be permitted.
-//
-// The result of running this analysis over a program is a set of unsafe pointer
-// types that cannot be transformed.  Safe pointer types are not tracked.
-//
-// Additionally, this analysis exports a hidden command line argument that (when
-// enabled) prints out the reasons a type was determined to be unsafe.  Just add
-// -printunsafeptrinst to the command line of the tool you want to get it.
