Long answer: > unsupported initializer for address space - Which address space (local or global)? Why is it creating an initializer? Not the place to discuss the specification, but, as far as I know there is no sentence that states "The memory is going to be initialized". On the contrary. And finally, notice that this patch https://reviews.llvm.org/D6078 states: - Sort of depends on clang patch to not emit all LDS objects with zeroinitializer anymore. I would say: the initialization is NOT expected or desired. MESA/llvm/clang has a bug. Claudio PS: I know, sorry.
