Subject: r600g: texture offsets for non-TXF instructions
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8419c5c3ce1489222268bf840c1d165ea8bc53ce;p=mesa.git

r600g: texture offsets for non-TXF instructions

All texture instructions can use offsets, not just TXF. Offsets into
the literals array were wrong, too.
