Martin Jambor: Compiling for HSA accelerators with GCC

The talk will describe the HSA development branch of gcc. We will describe what it can and cannot do, how it is structured so that it does not need LTO, and how it is going to co-exist with the other LTO-based accelerators. Because our effort primarily targets OpenMP 4.0, we will also describe what changes we deemed necessary in OpenMP expansion so that we can generate efficient GPGPU code. We will conclude by presenting plans to merge the branch to trunk.
