Subject: nvc0/ir: use manual TXD when offsets are involved
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=114d46829d10c826927cabc1ca14884a4ee249f7;p=mesa.git

nvc0/ir: use manual TXD when offsets are involved

Something about how we're implementing offsets for TXD is wrong, just
flip to the generic quadop-based implementation in that case.

This is the minimal fix appropriate for backporting.
