Subject: i965: Switch to roundf in HS/DS URB code.
X-Git-Tag: upstream/17.1.0~4570
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=74d8612eedb67b3e39b6ba3b7d4d85d93a3153cd;p=platform%2Fupstream%2Fmesa.git

i965: Switch to roundf in HS/DS URB code.

Matt intentionally switched the VS calculation to be float-based in
commit c1da15709a0c0c2775bd9e534f67c60f7dc95ce8.  Tessellation support
was written before this and rebased forward, and missed the change.

Now it's consistent.
