Hal Finkel 033e0a94cb Don't crash in SE dealing with ashr x, -1 ... ScalarEvolution::getSignedRange uses ComputeNumSignBits from ValueTracking on ashr instructions. ComputeNumSignBits can return zero, but this case was not handled correctly by the code in getSignedRange which was calling: APInt::getSignedMinValue(BitWidth).ashr(NS - 1) with NS = 0, resulting in an assertion failure in APInt::ashr. Now, we just return the conservative result (as with NS == 1). Another bug found by llvm-stress. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185955 91177308-0d34-0410-b5e6-96231b3b80d8		2013-07-09 18:16:16 +00:00
