Hi,
don't know anything about wined3d, but the code in
IWineD3DVertexShaderImpl_ExecuteSW could make use of 6 parameters. The
definitions should cover this.
I don't think so... the case for 6 parameters should be removed.
I can't find 6-parameter instructions in the ins table.
[otherwise this would have to be fixed in a lot of other places as well].
Although I would agree that it needs to be increased to 5 at the moment
(DEF takes 5 parameters, and DEFI would take 5 parameters if it wasn't
wrong in the table). Does anyone know what the status of software
shaders is at the moment - how well do they work?
What's a good testing app?

I find the multi-argument calls rather ugly, though I understand they
might be necessary for speed. However, I am currently trying to get
relative addressing tokens in shaders 2.0+ properly accounted for. We
can have up to... 5 extra tokens per instruction for relative
addressing. So, either all those multi-arg calls need to switch to
unpacking structures, or the number of arguments should be increased
up to 10. I think I'll ignore software shaders for now though - not
sure how to test them.
