Chris Lattner fddcf47a24 make jump threading recursively simplify expressions instead of doing it ... just one level deep. On the testcase we go from getting this: F1: ; preds = %T2 %F = and i1 true, %cond ; <i1> [#uses=1] br i1 %F, label %X, label %Y to a fully threaded: F1: ; preds = %T2 br label %Y This changes gets us to the point where we're forming (too many) switch instructions on doug's strswitch testcase. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86646 91177308-0d34-0410-b5e6-96231b3b80d8		2009-11-10 01:57:31 +00:00
