David Majnemer 00428878bb InstSimplify: Fix a bug when INT_MIN is in a sdiv ... When INT_MIN is the numerator in a sdiv, we would not properly handle overflow when calculating the bounds of possible values; abs(INT_MIN) is not a meaningful number. Instead, check and handle INT_MIN by reasoning that the largest value is INT_MIN/-2 and the smallest value is INT_MIN. This fixes PR20199. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@212307 91177308-0d34-0410-b5e6-96231b3b80d8		2014-07-04 00:23:39 +00:00
