--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> --- >_ZN3ABCC4Ev That is the internal name of the function (it demangles to ABC::ABC() anyways) and the symbol does not need to be in the symbol table at all. We are going to run into this more with ICF also. I think there might have been a RFC about how to handle the debugging for commoning of functions but it might be a while before that is implemented.
