Chris Lattner 3bb4657488 Don't attempt to split subloops out of a loop with a huge number of backedges. ... Not only will this take huge amounts of compile time, the resultant loop nests won't be useful for optimization. This reduces loopsimplify time on Transforms/LoopSimplify/2006-08-11-LoopSimplifyLongTime.ll from ~32s to ~0.4s with a debug build of llvm on a 2.7Ghz G5. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29647 91177308-0d34-0410-b5e6-96231b3b80d8		2006-08-12 05:25:00 +00:00
