on llvmdev: SRoA is introducing MMX datatypes like <1 x i64>, which then cause random problems because the X86 backend is producing mmx stuff without inserting proper emms calls. In the short term, force off MMX datatypes. In the long term, the X86 backend should not select generic vector types to MMX registers. This is being worked on, but won't be done in time for 2.8. rdar://8380055 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112696 91177308-0d34-0410-b5e6-96231b3b80d8
