Subject: i965: Only flag the new-batch related state as dirty at new batch time.
X-Git-Tag: mesa-7.11-rc1~184
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=962dab948609c97c1c01fde6a27e19307948d302;p=platform%2Fupstream%2Fmesa.git

i965: Only flag the new-batch related state as dirty at new batch time.

This was debug code from the initial import of the driver.  No
statistically significant performance difference on cairo-gl or
nexuiz (n=6).
