copied from the SystemZ target. I don't think this causes any significant changes to the output (I compared the assembly, and the results appeared to be essentially unchanged), although I don't actually have an Alpha to test on. I would appreciate if anyone with the appropriate hardware could test this. I'm not sure if that includes anyone subscribed to llvm-commits, though. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76353 91177308-0d34-0410-b5e6-96231b3b80d8
