--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So what is happening is bar is being coming localized to the newly produced
assembly file which is the same as being hidden really.
If we do:
void bar() __attribute((visibility( "hidden" ), externally_visible));
The new assembly file in both cases produces:
.globl _Z3barv
.hidden _Z3barv
Without the externally_visible, the function does not have a .globl to it.
This is also why in both with and without -flto dynsym does not have the symbol
there.
There is no bug to be fixed, LTO is doing the localizing rather than the linker
doing it.
