================
Comment at: clang/lib/CodeGen/CGAtomic.cpp:1347-1348
           break; // Avoid crashing on code with undefined behavior
+        if (!OrderFail)
+          llvm::errs() << "FOO\n";
         EmitAtomicOp(*this, E, Dest, Ptr, Val1, Val2, IsWeak, OrderFail, Size,
----------------
debugging code should be removed


================
Comment at: clang/lib/Frontend/InitPreprocessor.cpp:510-514
+      Builder.defineMacro("__HIP_MEMORY_SCOPE_SINGLETHREAD", "1");
+      Builder.defineMacro("__HIP_MEMORY_SCOPE_WAVEFRONT", "2");
+      Builder.defineMacro("__HIP_MEMORY_SCOPE_WORKGROUP", "3");
+      Builder.defineMacro("__HIP_MEMORY_SCOPE_AGENT", "4");
+      Builder.defineMacro("__HIP_MEMORY_SCOPE_SYSTEM", "5");
----------------
these should be moved outside of if (LangOpts.CUDAIsDevice) as they need to be visible to both device and host compilation. The downstream amd-stg-open branch already did this.
