Hal Finkel 8c65549318 getSmallConstantTripMultiple should never return zero. ... When the trip count is -1, getSmallConstantTripMultiple could return zero, and this would cause runtime loop unrolling to assert. Instead of returning zero, one is now returned (consistent with the existing overflow cases). Fixes PR14167. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166612 91177308-0d34-0410-b5e6-96231b3b80d8		2012-10-24 19:46:44 +00:00
