Subject: i965/eu: Use current exec size instead of p->compressed in surface message generation.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=646213168ed1d2427f30cb92e783910a319cdbb4;p=mesa.git

i965/eu: Use current exec size instead of p->compressed in surface message generation.

This was kind of an abuse of p->compressed, dataport send message
instructions are always uncompressed.  Use the current execution size
instead since p->compressed is on its way out.
