Subject: i965: Fix Sandybridge regression introduced by workaround-free math.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=dceb202297b39220fbbcb41267077fb3ff8d137a;p=mesa.git

i965: Fix Sandybridge regression introduced by workaround-free math.

Commit a73c65c5342bf41fa0dfefe7daa9197ce6a11db4 had a typo which
accidentally enabled the workaround-free Gen7 code on Gen6.

Fixes GPU hangs in anything using pow() or integer division/modulus.
