Benjamin Kramer 33828bcb24 SimplifyCFG: Track the number of used icmps when turning a icmp chain into a switch. If we used only one icmp, don't turn it into a switch. ... Also prevent the switch-to-icmp transform from creating identity adds, noticed by Marius Wachtler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125056 91177308-0d34-0410-b5e6-96231b3b80d8		2011-02-07 22:37:28 +00:00
