Subject: i965: Remove unused structures for command packets.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3de9405763ad4b9e78577699ec206be7dda03374;p=mesa.git

i965: Remove unused structures for command packets.

We simply emit these using OUT_BATCH and bitshifting, as it results in
better compiled code than packed structures.  Since our documentation
is public, it's not terribly useful to keep these around for reference.
