Den foresl\u00e5ede mulighed er en del af infrastrukturen til at skabe isolerede milj\u00f8er i Arm CCA (Confidential Compute Architecture). RME giver almindelige programmer mulighed for at gemme deres fortrolige data i s\u00e5danne milj\u00f8er for at beskytte dem mod uautoriseret adgang i tilf\u00e6lde af kompromittering af operativsystemet og hypervisorer.\n<li class=\"l\"> Der er blevet implementeret nye muligheder i linkeren:\n<ul>\n<li class=\"l\"> '-Bno-symbolic' \u2014 deaktiverer '-Bsymbolic' og '-Bsymbolic-functions' muligheder;\n<li class=\"l\"> '-z report-relative-reloc' \u2014 viser information om dynamisk binding af adresser (relocation);\n<li class=\"l\"> '-z start-stop-gc' \u2014 deaktiverer behandling af __start_* \/ __stop_* links under rensning af ubrugte sektioner af affaldsamleren.  <\/ul>\n<li class=\"l\"> I v\u00e6rkt\u00f8jet readelf er der tilf\u00f8jet muligheden '\u2014sym-base=0|8|10|16' for at v\u00e6lge formatet for visning af numeriske symboler.\n<li class=\"l\"> I v\u00e6rkt\u00f8jet nm er der tilf\u00f8jet muligheder: '-\u2014format=just-symbols' ('-j') for kun at udskrive symbolnavne og '-\u2014quiet' for at deaktivere diagnosebeskeder 'no symbols'.\n<li class=\"l\"> I v\u00e6rkt\u00f8jerne objcopy og strip er der tilf\u00f8jet muligheden '-\u2014keep-section-symbols' for at forhindre sletning af ubrugte sektioner under behandling af filer.\n<li class=\"l\"> I objcopy er der tilf\u00f8jet mulighederne '-\u2014weaken', '-\u2014weaken-symbol' og '-\u2014weaken-symbols' for at klassificere udefinerede symboler som weak-symbols.\n<li class=\"l\"> I readelf og objdump er muligheden for at vise indholdet af sektioner '.debug_sup' blevet implementeret, og links til separate filer med debug-information (debug info) er som standard aktiveret.    <\/ul>\n<p>Kilde: <a content=\"nofollow\" rel=\"nofollow\"
