Chris Lattner 05bb789430 Fix PR1938 by forcing the code that uses an undefined value to branch one ... way or the other. Rewriting the code itself prevents subsequent analysis passes from making contradictory conclusions about the code that could cause an infeasible path to be made feasible. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46427 91177308-0d34-0410-b5e6-96231b3b80d8		2008-01-28 00:32:30 +00:00
