[PATCH] D75012: [ReleaseNotes] Mention -fmacro-prefix-map and -ffile-prefix-map.

[Fangrui Song via Phabricator via cfe-commits]

MaskRay added inline comments.


================
Comment at: clang/docs/ReleaseNotes.rst:142
+- ``-fmacro-prefix-map=OLD=NEW`` allows a directory prefix ``OLD`` in
+  ``__FILE__`` preprocessor macros to be substituted for ``NEW``. This helps
+  with reproducible builds that are location independent. The new
----------------
It affects `__FILE__` (C99) `__BASE_FILE__` (GNU extension) and `__FILE_NAME__` (clang extension).

Should such change be committed directly to the release/10.x branch by @hans ?
