Deze nieuwe modus maakt het mogelijk om een set opties voor verbeterde bescherming tegelijk te activeren, vergelijkbaar met de toegevoegde vlag '-fhardened' in GCC 14, waarbij de opties '-D_FORTIFY_SOURCE=3 -D_GLIBCXX_ASSERTIONS -ftrivial-auto-var-init=zero -fPIE -pie -Wl,-z,relro,-z,now -fstack-protector-strong -fstack-clash-protection -fcf-protection=full' worden ingeschakeld.     <\/p>\n<p>Het wordt opgemerkt dat er momenteel wordt gewerkt aan het toevoegen van beveiligingsfuncties aan de C- en C++-standaarden, maar dit proces gaat niet snel, terwijl in Clang al afzonderlijke opties beschikbaar zijn met de implementatie van extra beveiligingsmechanismen. De ge\u00efmplementeerde beveiligingsmethoden leiden vaak tot incompatibiliteit met bestaande code of schending van de ABI, waardoor ze niet standaard kunnen worden ingeschakeld. Bovendien zijn dergelijke opties verspreid (compilatieflags, machine-instructie-generatieflags gekoppeld aan hardwarearchitecturen, waarschuwingen, diagnostische modi, macro's), slecht gedocumenteerd en vallen ze buiten het zicht van veel ontwikkelaars.       <\/p>\n<p>\u00c9\u00e9n enkele instelling vereenvoudigt het inschakelen van de aan beveiliging gerelateerde opties en vergemakkelijkt hun toepassing. Er worden verschillende manieren overwogen om de beveiligingsversterkingsmodus te activeren, bijvoorbeeld via de vlag '-fhardened', de instelling '--config=hardened', een aparte besturing (clang --driver-mode) of afzonderlijke opties '-fhardened, -mhardened en -Whardened', gekoppeld aan compilatie, codegeneratie en waarschuwingen. De modus kan omvatten:  <\/p>\n<ul>\n<li class=\"l\"> Compilerfuncties: -ftrivial-auto-var-init, -fPIE, -fcf-protection, enz.\n<li class=\"l\"> Functies gekoppeld aan codegeneratie voor doelplatforms: -mspeculative-load-hardening, -mlvi-hardening, enz.\n<li class=\"l\"> Waarschuwingen: -Wall, -Wextra, -Werror=return-type, enz.\n<li class=\"l\"> Veiligheidsmodi in de standaard functie bibliotheek.\n<li class=\"l\"> Macro's: _FORTIFY_SOURCE, _GLIBCXX_ASSERTIONS, enz.\n<li class=\"l\"> Vereiste expliciete keuze voor de gebruikte programmeertaalstandaard.\n<li class=\"l\"> Weigering om code te compileren die gebruik maakt van verouderde standaarden C89 en C++98.\n<li class=\"l\"> Doorgeven van extra linkerflags, bijvoorbeeld voor het inschakelen van adresrandomisatie.
