dblaikie added a comment.
What happens for this program:
extern void f1();
void f2(void *);
inline void f3() {
f2(f1);
}
...
Even when `f3` is never called, I'm guessing your change will cause `f1` to be
emitted?
Also something like this:
void f1();
int main() {
int x = sizeof(&f1);
}
Does that produce the declaration of `f1` too?
================
Comment at: clang/lib/CodeGen/CGExpr.cpp:2840
+ // Emit debuginfo for the function declaration if the target wants to.
+ if (getContext().getTargetInfo().allowDebugInfoForExternalVar()) {
+ CGDebugInfo *DI = CGM.getModuleDebugInfo();
----------------
Seems like this should be renamed given it's being used for things other than
external variables?
