Subject: nir: Zero out texture instructions when creating them.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fb2425a641dd7f891964e6f51b10cce63dff7d2c;p=mesa.git

nir: Zero out texture instructions when creating them.

There are so many flags in textures, that the CSE pass would have a hard
time referencing the correct set when figuring out if two texture ops are
the same.  By zeroing, we can avoid that fragility.
