Subject: panfrost/midgard: Don't force constant on VLUT
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4f7460297bcb07605f05e91236346aeedd0f0c16;p=mesa.git

panfrost/midgard: Don't force constant on VLUT

Previously, we forced a #0 inline constant tacked on for the lut
instructions to mirror the blob's behaviour, which caused some
suboptimal codegen due to our constant inlining implementation. Instead,
just don't force a constant at all.
