The code in X86TargetLowering::LowerEH_RETURN() assumes that a frame pointer exists, but the frame pointer was forced by the presence of llvm.eh.unwind.init which isn't guaranteed. If llvm.eh.unwind.init is actually required in functions calling eh.return (is it?), we should diagnose that instead of emitting bad machine code. This should fix the dragonegg-x86_64-linux-gcc-4.6-test bot. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158961 91177308-0d34-0410-b5e6-96231b3b80d8
