10// This is a legacy redirect header for the old PassManager. It is intended to
11// be used by clients that have not been converted to be aware of the new pass
12// management infrastructure being built for LLVM, which is every client
13// initially. Eventually this header (and the legacy management layer) will go
14// away, but we want to minimize changes to out-of-tree users of LLVM in the
15// interim.
16//
17// Note that this header *must not* be included into the same file as the new
18// pass management infrastructure is included. Things will break spectacularly.
19// If you are starting that conversion, you should switch to explicitly
20// including LegacyPassManager.h and using the legacy namespace.
