The 'optnone' attribute means don't inline anything into this function
(except functions marked always_inline). Functions with 'optnone' must also have 'noinline' so they don't get inlined into any other function. Based on work by Andrea Di Biagio. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195046 91177308-0d34-0410-b5e6-96231b3b80d8
