xazax.hun added a comment. I think a crucial part of the design is what would we do for the following case:
if (x < y || x > z) return; // Here we might not have ranges for x when y and z were symbolic. mySink(x); // requires x to be in [0, 255] So would we warn for the code above? X is certainly in SOME bounds but we were not smart enough to figure out what. And these symbolic constraints are not recorded in the range based constraint manager. If we want to avoid potential false positives on the code above we do need to somehow record symbolic constraints somewhere.
