Subject: vc4: Initialize pack field of qreg to 0 in qir_get_temp
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=48de40ce9c45de154965490843f9e50407970c26;p=mesa.git

vc4: Initialize pack field of qreg to 0 in qir_get_temp

This avoids generation of undefined packing in qir and qpu instructions,
fixing a lot of rendering errors.

Fixes 8b36d107fdd (vc4: Pack the unorm-packing bits into a src MUL
instruction when possible.)
