Subject: i965/fs: Invalidate live intervals after copy propagation.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1e28f55ab7909496d93ab1b552faad17453c10ac;p=mesa.git

i965/fs: Invalidate live intervals after copy propagation.

For copy propgation, we've dropped the use of a GRF in favor of a
(probably later) use of a different GRF.  This definitely requires
invalidating intervals.
