Subject: freedreno/a3xx/compiler: fix p0 (kill, etc)
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2f181bc3919b87b8bebfae7ad8568330d1780193;p=mesa.git

freedreno/a3xx/compiler: fix p0 (kill, etc)

Don't assert (debug builds) or assign random uninitialized value for
predicate register (p0).. that screws up kill, etc.
