No. I think this is exactly what is causing problem here. eg: if we have two weak symbols （weak_func）, and we generate the weak counter/data as usual: __llvm_prf_cnts: __profc_weak_func(1): __profc_weak_func(2): __llvm_prf_data: __profd_weak func(1): Pos_Rel __profc_weak_func <=== Relocation to calculate the relative pointer __profd_weak_func(2): Pos_Rel __profc_weak_func <=== Relocation to calculate the relative pointer The relative pointer calculation in __profd_weak_fun will be wrong after linking.
