Compilers don't (baring bugs in the compiler or misunderstandings by the 
compiler writers) do transformations that are illegitimate or lead to 
different semantics.  There's no need for warnings about them.  All 
defined behaviours before the transformation will have the same defined 
behaviour after the transformation.

The only way to get different effects is if the behaviour /before/ the 
transformation was undefined.  And then there is no way, in general, for 
the compiler to know if the behaviour was changed by the transformation 
as it had no definition previously.

This is all standard computer science theory.  You start with code that 
has a precondition and a postcondition - the code guarantees that as 
long as the precondition is fulfilled, running the code will fulfill the 
postcondition.  A transformation - optimisation, implementation, code 
generation, whatever - is valid as long as the precondition is not 
strengthened and the postcondition is not weakened.  At no point does 
the implementation, or transformed code, or the transformer (compiler / 
optimiser) have to check the precondition - it can assume it is true.

The C statement "int x = *p;" has the precondition that "p" is a valid 
pointer pointing to an int object.  The postcondition is that "x" 
contains the value of the int at the address contained in "p".  The code 
does not say anything about what will happen if "p" does not point to a 
valid int object.  So the transformed code can do anything it likes in 
such a case.

Optimisations don't change the functionality of code.  But you have to 
remember that the functionality of the code is only defined when the 
precondition is satisfied - code has no functionality outside of that.
