Okay, thanks - probably not needed for now (should be separate patch to handle new functions in C 2X anyway; maybe more functions to be added?) >> Also, just to double-check: we don't encode restrict into builtin >> signatures, do we? (Should we?) Maybe catch very simple overlap issues? I dont think this is worth it (we have sanitizers). LLVM annotates libc functions with noalias anyway.
