Prior to this change, the considered addressing modes may be invalid since the maximum and minimum offsets were not taking into account. This was causing an assertion failure. The added test case exercices that behavior. <rdar://problem/14199725> Assertion failed: (CurScaleCost >= 0 && "Legal addressing mode has an illegal cost!") git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184341 91177308-0d34-0410-b5e6-96231b3b80d8
