Subject: gm107/ir: fix texturing with indirect samplers
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ecea2f69ef8c07bd7b08f659b214a83f64ea2daa;p=mesa.git

gm107/ir: fix texturing with indirect samplers

The indirect handle has to come right after the coordinates, so if there
was a sample/bias/depth compare/offset, everything would end up being
shifted by one argument position.
