I think a GPU backend would be well beyond the scope of a Summer of
Code project. GPUs don't have normal stacks and addressing support
is limitted.

A project that started and ended here would give GCC, in particular
GCC's Cell SPU port, the only major required functionality in the OpenCL
language, outside the runtime, that GCC is missing.

Do you mean just conversion only support, like Sandra Loosemore's
proposed ARM patch, or full arithmetic support like any other scalar or
vector type?
