[PATCH] D148805: [Clang][OpenMP] Avoid emitting a __kmpc_alloc_shared for implicit casts which do not have their address taken

[Alexey Bataev via Phabricator via cfe-commits]

ABataev added inline comments.


================
Comment at: clang/lib/CodeGen/CGOpenMPRuntimeGPU.cpp:448
       return;
-    if (E->getCastKind() == CK_ArrayToPointerDecay) {
-      const bool SavedAllEscaped = AllEscaped;
----------------
I think you need to check that the array is allocated in the parallel context, otherwise there might be a crash, if it is allocated in the target context and many threads would like to access it.
