================
Comment at: clang/lib/Sema/SemaDecl.cpp:15258
+  // units.  Deleted and Defaulted functions are implicitly inline (but the
+  // inline state is not set at this point, so check the BodyKind explicitly).
   if (getLangOpts().CPlusPlusModules && currentModuleIsHeaderUnit() &&
----------------
I prefer to add a FIXME here to say that we need to find a better place for the check to eliminate the unnecessary check for `BodyKind `. The current check for `BodyKind` looks a little bit hacky to me.


================
Comment at: clang/lib/Sema/SemaDecl.cpp:15261
+      FD->getFormalLinkage() == Linkage::ExternalLinkage &&
+      !FD->isInvalidDecl() && BodyKind == FnBodyKind::Other &&
+      !FD->isInlined()) {
----------------
It looks like we need to check `FD->isThisDeclarationADefinition()` too.

And personally, I prefer to check BodyKind explicitly. Otherwise the readers need to checkout the definition of `FnBodyKind` to understand the code.
