Re: [Mesa3d-dev] Does DX9 SM3 -> VMware svga with arbitrary semantics work? How?

Any Gallium driver should be able to support the GLSL subset without
control flow.

And if we had a proper optimization infrastructure capable of inlining
functions, converting conditionals to multiplications and unrolling
loops (e.g. look at what the nVidia Cg compiler does), then
essentially all GLSL could be supported on any driver, with only
limitations on the maximum number of loop iterations.

Isn't it worth supporting that?

BTW, proprietary drivers do this: for instance nVidia supports GLSL on
nv30, which can't do control flow in fragment shaders and doesn't
support SM3.
