[Mesa-dev] [PATCH 0/7] Move shader_group_vote and shader_ballot to using intrinsics

[Nicolai Hähnle]

Hi all,

As Matt Turner pointed out on IRC, the builtin functions from those
extensions have an unusual interaction with control-flow, which is not
captured by the usual semantics of expressions. For this reason, they should
really be implemented as intrinsics.

The last two patches are related cleanup in st/glsl_to_tgsi.

Please review!
Thanks,
Nicolai
