> It would be great if we can dissect it down to specific cases in mind and discuss how to solve these cases, I see two kinds of problems: > > * (1) EvalSet need to be aware of the bound of Vars > > * Ideally these bounds should be populated in the analyzer via bind. > * (2) `floormod([13, 15], 10) => [3, 5]` : This seems to be a clean case that we can fix first(independent from the Var bound problem), how about we create a separate PR for the var bound case and aim at fixing this one? > > * For `floormod([a, b], c)`: check if we can prove `floordiv(a, c) == floordiv(b, c)`, if so, we rewrite to `[a - floordiv(a, c) * c, b - floordiv(b, c) * c]`, otherwise, follow the old rule. > * Same rule can be applied to ConstIntBound This is also how I categorized the issues. I can certainly make the second part a separated PR. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
