      Both posted recently in the ML (1 o 2 weeks ago at the maximum, the V3 o V4 version) and both seem ready to be included.

          Hosana! Good news! The both GL_ARBs seem to be mature and fully implementable. Many thanks to the developers!

            I can't find the source for this. Could anyone point me to it?

                  hopefully in the next week, we can merge tess and shader subroutine to master which will give nvc0 4.1, and then radeonsi tess code along with a couple of bits of ARB_gpu_shader5 which I've written but need some llvm changes to work properly. Intel users will have to wait until someone figures out tess and an fp64 strategy. It looks like for fp64 Intel like most r600 gpus will need a softfloat implementation of some sort.
