 // RUN:  --check-prefixes=CHECK,CHECK-EXTERN
+// RUN: %clang_cc1 -std=gnu2x -triple x86_64-linux-gnu %s -emit-llvm -o - \
+// RUN:  -mfunction-return=thunk-extern -fprofile-arcs \
----------------
I feel that having 3 RUN lines is excessive. Since we already have a test that asan/tsan/gcov respect getModuleFlag, it is not necessary for a new one to duplicate all the combinations.

Comment at: llvm/docs/LangRef.rst:7370
   a synthesized function will get the ``uwtable(async)`` function attribute.
+- "fn_return_thunk_extern": The synthesized function will get the
+  ``fn_return_thunk_extern`` function attribute.
----------------
keep the list sorted
