yaxunl accepted this revision. yaxunl added a comment. This revision is now accepted and ready to land. LGTM. Thanks. I missed the addr space casts you added to CodeGenFunction::EmitBuiltinExpr. With those casts it should work. For other downstream address space agnostic languages, e.g. (HCC),

[PATCH] D47154: Try to make builtin address space declarations not useless

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

arsenm created this revision. arsenm added reviewers: Anastasia, yaxunl, rjmccall. Herald added subscribers: tpr, nhaehnle, wdng. The way address space declarations for builtins currently work is nearly useless. The code assumes the address spaces used for builtins is a confusingly named "target a
