Chris Lattner a75d3b6d0d 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. llvm-svn: 29647		2006-08-12 05:25:00 +00:00
