URL: https://github.com/llvm/llvm-project/commit/6f770292a000039f265c985623b1550aa50566b0 DIFF: https://github.com/llvm/llvm-project/commit/6f770292a000039f265c985623b1550aa50566b0.diff LOG: [OpenCL] Restrict pointer to member functions. Pointers to member functions are a special case of function pointers and therefore have to be disallowed.
