[PATCH] D109080: [docs] Mention that the legacy PM is deprecated and will be removed after 14

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

This should also be cherry picked into release/13.x



================
Comment at: llvm/docs/ReleaseNotes.rst:60
+* Using the legacy pass manager for the optimization pipeline is deprecated and
+  will be removed after LLVM 14.
 
----------------
Worth a bit more detail like

"only a minimal level of effort need be made to maintain performance of the legacy pass manager" for the LLVM 14 release as mentioned by @ctetreau , or perhaps phase more briefly.
