Hi, I was dabbling with C++11 a while ago and had code generation problems with atomic operations (see here: https://groups.google.com/forum/#!searchin/emscripten-discuss/C$2B$2B11$20atomic/emscripten-discuss/UN1moUZilrM/m_Qm1KSVGrQJ)
The good news is that this specific problem seems to be fixed with clang3.4 in the fastcomp backend, however, I'm now getting linker errors where LLVM wants to call CRT functions for atomic operations: warning: unresolved symbol: __atomic_store_1 warning: unresolved symbol: __atomic_load_4 warning: unresolved symbol: __atomic_load_1 warning: unresolved symbol: __atomic_fetch_sub_4 warning: unresolved symbol: __atomic_store_4 warning: unresolved symbol: __atomic_fetch_add_4 warning: unresolved symbol: __atomic_compare_exchange_4 I'm wondering now how to treat this type of problem onward. I'm currently having ifdefs for emscripten around this code, basically treat some subset of C++11 as platform-specific and have an emscripten-specific implementation (which would very likely be more efficient anyway, since it's just basic load/add/sub instead of calling into a function). Is there a plan / time-line for missing C++11 stuff, and is there a list somewhere what C++11 areas don't work? I assume thread (obviously), atomic, and chronos? These are the only areas which I had trouble with so far btw, other C++11 stuff seems to work fine.
