Hi, I'm part of an engineering team doing research on persistent memory support and we have stumbled upon an interesting problem. The issue is, we would like to be able to use the standard library containers in a persistent memory context (think NVDIMM-N). What I mean is that you allocate a container from said memory, use it like you normally would. After the application terminates, expectedly

for example /// getPointerUnionTypeNum - If the argument has type PT1* or PT2* return /// false or true respectively. template <typename PT1, typename PT2> static inline int getPointerUnionTypeNum(PT1 *P) { return 0; } template <typename PT1, typename PT2> static inline int getPointerUnionTypeNum(PT2 *P) { return 1; } template <typename PT1, typename PT2> static inline int getPointerUnionTypeNum(...) { retur...

.... That's why they're there. The reason to use the pointer-length pair in preference to iterators is that iterators make templates of everything, causing code bloat. In my code, rather than pass the separate parameters I use a range<Iter> class something like this: template<typename Iter> class range { Iter Begin, End; public: range() : Begin(), End() { } template<typename ConvertibleToRange> range(T &seq) : Begin(seq.begin()), End(seq.end()) { } Iter begin() { return Begin; } Iter end() { return End; } // ... other Sequence methods ... };...

I suppose the solution is to switch to SmallVector whenever this might be a problem. I'm a bit concerned that any new &empty[0] problems that are introduced will go unnoticed.

Hi all I had written a gdb macro to dump the string representation of an SEXPREC type when I realised everything I needed was in inspect.c already in the typename() function. However, the typename function doesnt handle the RAWSXP type, so if possible, could the following patch be applied (I've just put in inline as it is a trivial 1-liner)?

Moving to LLVM dev to discuss the possibility of extending the cast infrastructure to handle this.

Thanks, Shahid. It is fixed now.
