 ; NVPTX-DISABLED-NEXT:    [[DOTTHREADID_TEMP_:%.*]] = alloca i32, align 4
-; NVPTX-DISABLED-NEXT:    store i32 0, i32* [[DOTZERO_ADDR]], align 4
 ; NVPTX-DISABLED-NEXT:    [[TMP0:%.*]] = call i32 @__kmpc_target_init(%struct.ident_t* @[[GLOB1]], i1 false, i1 false, i1 true)
----------------
Can we do further? Since the store to this variable is removed, its value now is meaningless. We don't have to pass it to the function call below, and we can remove the argument for the callee, and we don't need to allocate this variable.
