Subject: nv50: don't crash on TXD opcode
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7f3de70c3c8e9ec9dfc34ddd3a08c4b73c007541;p=mesa.git

nv50: don't crash on TXD opcode

It doesn't implement full TXD, but at least it does not crash.
Fixes arb_shader_texture_lod-texgrad and glsl-fs-shadow2DGradARB-*
piglit tests.
