>From a quick look, I'd say this does not reflect the current design: The types are named differently, have a different layout (SoA vs AoS) and there's no implementation of `__tgt_target_mapper` in this patch as @grokos mentioned.
Moreover, I'd question the following things:

1. Why are we back to `__kmpc_?` naming? Most other functions specific to libomptarget are called `__tgt_?`.
2. Do you really want to construct `std::vector`s in the compiler generated code? That's bound to cause trouble with Fortran, isn't it?
