Nick Lewycky dd643f26c4 Add a utility function that detects whether a loop is guaranteed to be finite. ... Use it to safely handle less-than-or-equals-to exit conditions in loops. These also occur when the loop exit branch is exit on true because SCEV inverses the icmp predicate. Use it again to handle non-zero strides, but only with an unsigned comparison in the exit condition. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59528 91177308-0d34-0410-b5e6-96231b3b80d8		2008-11-18 15:10:54 +00:00
