X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=62f6fac1c500c9d6cb287db395d9ab3cbd985de9;p=oota-llvm.git

Put HasAVX512 predicate on some patterns to properly disable them when AVX512 isn't enabled. Currently it works simply because the SSE and AVX version of the same patterns are checked first in the DAG isel table.
