// This function exists to help with generation of callstacks for exceptions
// on iOS and MacOS x64 with clang 6.0 (newer versions of clang don't have this
// problem on x64). There we call the backtrace function, which does not play nicely
// with NORETURN, since the compiler eliminates the method prologue code setting up
// the address of the return frame (which makes sense). So on iOS we need to make
// the NORETURN define do nothing, then we use this dummy method which has the
// attribute for clang on iOS defined to prevent clang compiler errors for
// method that end by throwing a managed exception.
