[Mesa-dev] [rfc] softpipe compute shader support

[Dave Airlie]

This isn't complete yet, but it passes all the piglit tests,
the main missing bit is completing the atomic operations.

This is based on some tgsi fixes I've sent out previously,

The full branch is also here:
https://cgit.freedesktop.org/~airlied/mesa/log/?h=softpipe-compute

I just wanted to send this out to see if anyone has any comments
on the approach I've taken to make this work, esp the restartable
TGSI machine and execution model of the barriers.

Dave.
