--- Comment #1 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
As per bug 109194, much of these aren't actually true; consider when b ==
INT_MAX.
Then b + 1 is undefined, but we may want to treat it as INT_MIN.
So (a <= b) doesn't necessarily imply much about a + M <= b + N
As also noted in bug 109193 and bug 109194, the constraint_manager has some
heuristics to try to handle common cases, but ultimately we're probably going
to want to hand this off to an SMT solver (PR 104940)
*** This bug has been marked as a duplicate of bug 104940 ***
