Chris Lattner	946b255977	Initial checkin of a simple loop unroller. This pass is extremely basic and limited. Even in it's extremely simple state (it can only fully unroll single basic block loops that execute a constant number of times), it already helps improve performance a LOT on some benchmarks, particularly with the native code generators. llvm-svn: 13028	2004-04-18 05:20:17 +00:00

Initial checkin of a simple loop unroller. This pass is extremely basic and

limited.  Even in it's extremely simple state (it can only *fully* unroll single
basic block loops that execute a constant number of times), it already helps improve
performance a LOT on some benchmarks, particularly with the native code generators.
