The problem is that it needs also source style scoping also:
take:
int f(int *a);
int g(int b)
{
{
int c;
f(&c);
}
{
int c1;
f(&c1);
}
}Without source based ones, we don't know if c/c1 can ever be shared. I have code here at Sony where we actually depend on this behavior with large structs (and arrays). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32327
