Subject: r300/compiler: TEX instructions don't support negation on source arguments
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1e97b4dd103a00f497cc92571498ffd7178ba263;p=mesa.git

r300/compiler: TEX instructions don't support negation on source arguments

This fixes piglit:
- glsl-fs-texture2d-dependent-4

NOTE: This is a candidate for the 7.9 and 7.10 branches.
