* Richard Kenner:
int f(int a, int b) { return 0 * (a + b); }Why? Is there any language that requires such semantics?
get the potentially trapping arithmetic folded away. If -ftrapv is to have properly defined semantics, those must include trapping if (a + b) overflows in the above code.
Standard ML. I don't think there is a GCC front end (and it's not likely that one will be feasible, at least until GCC supports a fitting garbage collector).
