Hi Hans,
All pushed. I made a few additional fixes and improvement to fp64
immediate handling along the way, but all your commits were fine
as-is. (Except that they enabled fp64 immediates on nv50 implicitly
which is wrong -- there are no immediate-taking variants on nv50, so I
fixed that glitch. But only the G200 can do fp64 in the first place,
and nouveau doesn't actually expose it. Corner case of a corner case
:) )
Right, I did actually think about that one a bit since Compute capability
1.3 does include doubles, but I figured that since we do not support doubles
on nv50 at all that that would not be an issue, guess I should have
mentioned this in one of the commit messages.
Thanks for taking care of this... it was a small bit of fp64 which I
always felt bad about not having finished up. (But not bad enough to
actually finish it myself.)
You're welcome, this was a fun learning experience for me and I look
forward to doing more work on the codegen bits in the future. But for now
I will be spending my time on a tgsi backend for llvm, so sorry I will
not be looking into:

Anytime soon, but I do plan to work more on the codegen code in the
future. I will make sure to coordinate with you when I have time to
work on codegen again to avoid doing double work.
Regards,
Hans
