when run on an Intel Atom processor. The failures have arisen due to changes elsewhere in the trunk over the past 8 weeks or so. These failures were not detected by the Atom buildbot because the CPU on the Atom buildbot was not being detected as an Atom CPU. The fix for this problem is in Host.cpp and X86Subtarget.cpp, but shall remain commented out until the current set of Atom test failures are fixed. Patch by Andy Zhang and Tyler Nowicki! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160451 91177308-0d34-0410-b5e6-96231b3b80d8
