Is the compiler able to use that for optimizations (eg. hold
const variables in registers, etc) ?
BTW: in java (AFAIK) there's a lot more room for such optimizations,
eg. somehing like:
...
String static final prefix = "/foo/";
...
String foo = prefix+"bar";
System.out.println(foo);
could be optimized to:
System.out.println("/foo/bar");
> Modifying a const object via a non-const lvalue is undefined behaviour.
Is there a flag to forbid that ?
