tra added a comment. CUDA does not expose explicit AS on clang size. All pointers are treated as generic and we infer specific address space only in LLVM. `__nvvm_atom_*_[sg]_*` builtins should probably be removed as they are indeed useless without pointers with explicit AS and NVCC itself does not have such builtins either. Instead, we should convert the generic AS builtin to address-space specific instruction somewhere in LLVM.
Using `attribute((address_space())` should probably produce an error during CUDA compilation. https://reviews.llvm.org/D47154 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
