[Mesa-dev] [PATCH 2/9] i965/vec4: Initialize LOD to 0.0f.

[Matt Turner]

We implement textureQueryLevels (which takes no arguments, save the
sampler) using the resinfo message (which takes an argument of LOD).
Without initializing it, we'd generate a MOV from the null register to
load the LOD argument.
