I have a hard time seeing why this would be all that worthwhile.
Since the instruction sets for AMD, NVIDIA or current Intel GPUs are
trade scretes, GCC won't be able to generate binary output for them.
OpenCL is designed for heterogenous systems, compiling for multi-core or
single-core CPUs would only be useful as a cheap fallback implementation.
This limits a GCC-based OpenGL implementation to achieving it's primary
purpose with just Cell processors and maybe Intel's Larrabee. Is that
what you envision? Without AMD/NVIDIA GPU support it doesn't sound all
that useful to me.
