search for: remove_reference

Hey there, lld fails to build on Visual Studio 2013 because of ErrorOr<void>. For example, ErrorOr<void> is used in InputGraph.h as the return type of InputGraph::reset. Inside of ErrorOr, there is: typedef typename remove_reference<T>::type &reference As T is void, and remove_reference <T>::type results in void, the typedef expands to: typedef void & reference, which looks rather invalid. So the punchline is this: In Visual Studio 2012, the statement typedef remove_reference <T>::type & referenc...

This is partly an llvm question, and maybe partly C++. I am trying to make calls on code in the llvm infrastructure.(3.4.2) I appear to be missing some include files, but don't know how to track them down. I get compile errors on existing llvm header files, like the following two examples: -------------------------------------------------------------------------------- In file included
