...es, given that LLVM will allow C++17 features in a few months. For example: * Can we use auto in the initializer of range-for statements? * Can we use auto in the initializer of if() statements? * Can we use auto with llvm:Optional instances? * Can we use auto in c++14 lambda arguments with llvm::find_if(C, [](const auto& i) { ... }) for example? * We need to use auto for structured bindings, if those are used. I know some people are very opposed to use of auto except in exceptional circumstances, but * Some features force it a bit * Elsewhere it is becoming more common for it to be reasona...

Hi all, My app uses prefixes for user-defined labels and directory names. Since these are case-sensitive, I chose XLABEL and XDIR respectively. Labels and directories may start with an upper-case, so a ":" is always inserted between the prefix and the term itself. These prefixes are mapped with add_boolean_prefix to "dir" and "label". Let's imagine I index a

It seems MemorySSA.cpp is the only real code where we found the problem happening. Is it possible to change the source of MemorySSA.cpp to hide the problem and buy some time for now? Now we use an empty generic_def_path_iterator with Optional<ListIndex> N being initialized by None as the end of range. Can we initialize the Optional var with a special value instead of None?
