Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- See Also| |https://github.com/itanium- | |cxx-abi/cxx-abi/issues/74 --- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Any use of std::hardware_destructive_interference_size and std::hardware_constructive_interference_size for ABI purposes in a header file is very much discouraged and GCC will (or should be) warn about them . So the value is not wrong just needs improvement.
