Compiler does not simply see such code, it happens after some analysis, right?
For example, after work of infer_loop_bounds_from_undefined which makes some
assumptions and I believe can produce some information for user.
Again, I'm worrying about all this from user-perspective and especially after
discovering 2 such things in spec2006 sources(PR53086 and PR53073).
Interesting, could people have problems with SPEC results reporting since they
have to modify sources for this?
