rnk added a comment.
This is an interesting test case, though:
inline int foo() {
static int __attribute__((internal_linkage)) x;
return x++;
}
If foo gets inlined, those call sites will use and update 'x'. If foo is not
inlined, one definition of foo will win, and every caller will use its version
of 'x'.
We could emit a warning, but I kind of don't care. If you're using
internal_linkage, you are operating outside the rules of C++. You're expecting
multiple copies of these things to be emitted.
