Subject: pan/bi: Fix spilling on Valhall
X-Git-Tag: upstream/22.3.5~10796
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fe9cf1d0a4564a6f9b75ee04f266c7d180522de5;p=platform%2Fupstream%2Fmesa.git

pan/bi: Fix spilling on Valhall

We need a slightly different idiom on Valhall, since the segment modifiers no
longer exist but we now have an immediate offset.
