Subject: i965/fs: Allow SIMD16 with control flow on Ivybridge.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=79cba4c2b17456e2b25ac555c45e1c106b4e3f6b;p=mesa.git

i965/fs: Allow SIMD16 with control flow on Ivybridge.

The check was designed to forbid it on old generations (Gen5/Ironlake),
not on new ones.  It just works on Gen7/Ivybridge.
