Subject: nir/lower_tex: Use tex_instr_dest_size for txs destinations
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0bf0365393497d2d29fd24b4c42f17d5ad9bd4e2;p=mesa.git

nir/lower_tex: Use tex_instr_dest_size for txs destinations

Using coord_components of the source texture is correct for everything
except cube maps where it's off by one.
