Subject: ARM: Split out cost model vcvt testcases.
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=5eabdf2601d54d38976dba0967e10ef2942e6581;p=oota-llvm.git

ARM: Split out cost model vcvt testcases.

They had a separate RUN line already, so may as well be in a separate file.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179988 91177308-0d34-0410-b5e6-96231b3b80d8
