scott.linder added a comment. The rationale is that `-fvisibility` only affects the default, and already does not apply in many cases. For example, see the rest of the conditions above the fvisibility check in `getLVForNamespaceScopeDecl`: when `Var->getStorageClass() == SC_Static` the linkage is (usually) internal and the visibility is default. In cases where individual symbols need unique visibility an `__attribute__` can be used.
I think one question is whether OpenCL language semantics allow us to make these visibility determinations; I am going off of the APIs available to access symbols. https://reviews.llvm.org/D53153 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
