// This is a legacy redirect header for the old PassManager. It is intended to
// be used by clients that have not been converted to be aware of the new pass
// management infrastructure being built for LLVM, which is every client
// initially. Eventually this header (and the legacy management layer) will go
// away, but we want to minimize changes to out-of-tree users of LLVM in the
// interim.
//
// Note that this header *must not* be included into the same file as the new
// pass management infrastructure is included. Things will break spectacularly.
// If you are starting that conversion, you should switch to explicitly
// including LegacyPassManager.h and using the legacy namespace.
