Subject: [X86] Add missing (unsupported) zmm vector move classes
X-Git-Tag: upstream/17.0.6~33357
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=89e4cb603d96dcb962ec76aa5e91d6ce86ffe63b;p=platform%2Fupstream%2Fllvm.git

[X86] Add missing (unsupported) zmm vector move classes

Although unsupported on HSW, we reuse this model for KNL which does require them

Noticed when running the cost model fuzz script from D103695 with -mcpu=knl
