 LLVM currently contains two pass managers, the legacy PM and the new PM. The
-optimization pipeline (aka the middle-end) works with both the legacy PM and
-the new PM, whereas the backend target-dependent code generation only works
-with the legacy PM.
+optimization pipeline (aka the middle-end) uses the new PM, whereas the backend
+target-dependent code generation uses the legacy PM.
 
-For the optimization pipeline, the new PM is the default PM. Using the legacy PM
-for the optimization pipeline is deprecated and there are ongoing efforts to
-remove its usage.

 Some IR passes are considered part of the backend codegen pipeline even if
 they are LLVM IR passes (whereas all MIR passes are codegen passes). This
