--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> ---
Note one reason to omit the info might be that it should be available in the
debug information of the callee. The following simple patch makes the
desired debug information appear at both -O0 -g and -O -g for foo but
not for bar (which is unused):
extern void foo (int);
extern void bar (int);
int main()
{
foo (1);
}

The effect on debug info size would need to be evaluated (I'll check
GCC itself for this).
