[Frama-c-discuss] Jessie: Timeout for Simplify broken?

Not to sound negative, but you are repeatedly asking the people who
could help you to write a complete program with your snippets in it so
that they can see what verification conditions you are talking about.
Here, how about providing the Why text of the preconditions? You'll
get more precise answers faster if you provide precise questions, and
you will save everyone A LOT OF TIME.

So I wrote the program below, and got the VCs that follow. I'll let
someone else comment on them.

int f(int x, int y)
  return (x != y);

1 <= 2147483647

0 <= 2147483647
