Subject: r300/compiler: do not set TEX_IGNORE_UNCOVERED on r500
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6da4866ffdb19315bbb48f6778d1a5297b842a77;p=mesa.git

r300/compiler: do not set TEX_IGNORE_UNCOVERED on r500

The docs say it can be set for direct texture lookups, but even that
causes problems.

This fixes the wireframe bug:
https://bugs.freedesktop.org/show_bug.cgi?id=32688

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