In this instance we are generating the tail-call during legalizeDAG. The 2nd floor call can't be a tail call because it clobbers %xmm1, which is defined by the first floor call. The first floor call can't be a tail-call because it's not in the tail position. The only reasonable way I could think to fix this in a target-independent manner was to check for glue logic on the copy reg. rdar://10930395 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151877 91177308-0d34-0410-b5e6-96231b3b80d8
