Chris Lattner 2ab6a7358e Add support to the loop canonicalization pass to make it transform loops to ... have a SINGLE backedge. This is useful to, for example, the -indvars pass. This implements testcase LoopSimplify/single-backedge.ll and closes PR#34 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9065 91177308-0d34-0410-b5e6-96231b3b80d8		2003-10-13 00:37:13 +00:00
