vangthao added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/AMDGPUAlwaysInlinePass.cpp:125
         (AS == AMDGPUAS::LOCAL_ADDRESS &&
-         !AMDGPUTargetMachine::EnableLowerModuleLDS))
+         (!AMDGPUTargetMachine::EnableLowerModuleLDS || !GV.hasInitializer())))
       recursivelyVisitUsers(GV, FuncsToAlwaysInline);
