Subject: nvfx: fix nv30 vertex program scalar opcodes
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bf5ee5aa4f065b6e17a4cc9cd2e539c4290ff98c;p=mesa.git

nvfx: fix nv30 vertex program scalar opcodes

Apparently they have always been broken, even before unification.

Fixes a lot of stuff, starting from morph3d and lighting in teapot
with textures disabled.
