As it was already mentioned the plan was to use GLSL 4.30 for shader model 5. However, it shouldn't be much of a burden to also support SM5 bitwise opcodes with ARB_gpu_shader5.
Sure, but is there a reason to?
OpenGL 3.2 + GLSL 1.50 + ARB_gpu_shader5 + ARB_tessellation_shader + ARB_texture_view + whatever else is necessary should also work for d3d11 / SM5, no? That would eventually make a bunch of Mesa drivers support d3d11 which otherwise wouldn't (like my AMD REDWOOD which AFAICS will not ever get anything above GL 3.3 / GLSL 3.30 because it doesn't support doubles).
SM5 has doubles.
Those are only optional in SM5 though, see https://msdn.microsoft.com/en-us/library/windows/desktop/ff476876(v=vs.85).a... note 2 and https://msdn.microsoft.com/en-us/library/windows/desktop/ff476124(v=vs.85).a.... I'm pretty sure SM5 games generally don't require doubles.
Right, so sure.
