Dan Gohman 763bad1a2b Generalize isLoopGuardedByCond's checking to consider two ... SCEVUnknowns with identical Instructions to be equal. This allows it to analze cases such as the attached testcase, where the front-end has cloned the loop controlling expression. Along with r73805, this lets IndVarSimplify eliminate all the sign-extend casts in the loop in the attached testcase. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73807 91177308-0d34-0410-b5e6-96231b3b80d8		2009-06-20 00:35:32 +00:00
