Hi, Jose, I just initiated a discussion (RFC patch https://reviews.llvm.org/D69393) for llvm/clang to support user address_space attribute. I am not able to add your name in subscriber list as you probably not registered with llvm mailing list or phabricator. Just let you know so we can have an eventual proposal which will be also good for gcc. Please participate in discussion. Thanks, Yonghong
