[PATCH] D157332: [clang] Make init for empty no_unique_address fields a no-op write

[Eli Friedman via Phabricator via cfe-commits]

efriedma added a comment.

This approach looks fine.



================
Comment at: clang/lib/CodeGen/CGCall.cpp:5781
 
       // If the value is offset in memory, apply the offset now.
+      if (!isEmptyRecord(getContext(), RetTy, true)) {
----------------
The isEmptyRecord call could use a comment briefly explaining that empty records can overlap with other data.

The existing comment about the offset probably belongs inside the if statement.
