This pass is very old and quite useless, remove it.

// 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.
