Subject: i965: Test instruction compaction on all supported Gens
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3d661e60625492a0e9f7931856c7e97e2eb7ef50;p=mesa.git

i965: Test instruction compaction on all supported Gens

Note that there's no point in testing on G45, since its compaction is
the same as Gen5. Same logic applies to Gen7 variants and low-power
parts.
