When deriving the range of valid values of a scalar evolution expression might be a range [12, 8), where the upper bound is smaller than the lower bound and where the range is expected to possibly wrap around. We theoretically could model such a range as a union of two non-wrapping ranges, but do not do this as of yet. Instead, we just do not derive any bounds. Before this change, we could have obtained bounds where the maximal possible value is strictly smaller than the minimal possible value, which is incorrect and also caused assertions during scop modeling. llvm-svn: 294891 |
