Subject: i965: Don't bother with RNDZ for f2i.
X-Git-Tag: 062012170305~9805
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5afdfa222fa9ec8c54e7d6957d2680c37a9eb715;p=profile%2Fivi%2Fmesa.git

i965: Don't bother with RNDZ for f2i.

The default type conversion for MOV should be fine, and RNDZ actually
requires two instructions.
