Subject: i965/vs: Add annotation to more of the URB write.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6af968b6736c87c05ea579df50e23b6f23b900d4;p=mesa.git

i965/vs: Add annotation to more of the URB write.

While we had nice debug output for most of the instruction stream, it
was terminated by a series of anonymous MOVs and a send.
