================ Comment at: clang/lib/CodeGen/CGBuiltin.cpp:2844 + return RValue::get( + Builder.CreateArithmeticFence(ArgValue, ConvertType(ArgType))); + return RValue::get(ArgValue); ---------------- Does this say that the fence will be silently dropped if any of the fast math flags are disabled? Silently dropping something used for correctness makes me nervous. Is there a case where all of these flags are required for correct behavior of the fence?
