--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
I think the linker binds power to the definition you provide and LTO takes
advantage of this:
1
t.o 3
200 798ad5a738e1a69e PREVAILING_DEF_IRONLY power
213 798ad5a738e1a69e PREVAILING_DEF main
240 798ad5a738e1a69e RESOLVED_DYN atoi
this happens with binutils which already has the patch and both BFD and gold
behave this way.
Note this is a linker bug, not a GCC bug as can be seen from the resolution.
