Diese M\u00f6glichkeit ist Teil der Infrastruktur zur Erstellung isolierter Umgebungen der Arm CCA (Confidential Compute Architecture). RME erm\u00f6glicht es regul\u00e4ren Programmen, ihre vertraulichen Daten in solchen Umgebungen zu speichern, um sie im Falle einer Kompromittierung des Betriebssystems und von Hypervisoren vor unbefugtem Zugriff zu sch\u00fctzen.\n<li class=\"l\"> Im Linker wurden neue Optionen implementiert:\n<ul>\n<li class=\"l\"> '-Bno-symbolic' \u2014 hebt die Optionen '-Bsymbolic' und '-Bsymbolic-functions' auf;\n<li class=\"l\"> '-z report-relative-reloc' \u2014 gibt Informationen \u00fcber dynamische Adressverlinkungen (Relocation) aus;\n<li class=\"l\"> '-z start-stop-gc' \u2014 deaktiviert die Verarbeitung von __start_* \/ __stop_* Referenzen w\u00e4hrend der Bereinigung ungenutzter Abschnitte durch den Garbage Collector.  <\/ul>\n<li class=\"l\"> Dem Tool readelf wurde die Option \u2018--sym-base=0|8|10|16\u2019 hinzugef\u00fcgt, um das Format der Anzeige von numerischen Symbolen auszuw\u00e4hlen.\n<li class=\"l\"> Dem Tool nm wurden die Optionen: '--format=just-symbols' ('-j') zum Ausgeben nur der Symbolnamen und '--quiet', um die diagnostischen Nachrichten 'no symbols' zu deaktivieren, hinzugef\u00fcgt.\n<li class=\"l\"> Den Tools objcopy und strip wurde die Option '--keep-section-symbols' hinzugef\u00fcgt, um das L\u00f6schen ungenutzter Abschnitte bei der Datei-Verarbeitung zu verhindern.\n<li class=\"l\"> In objcopy wurden die Optionen '--weaken', '--weaken-symbol' und '--weaken-symbols' hinzugef\u00fcgt, um nicht definierte Symbole als weak-Symbole zu kennzeichnen.\n<li class=\"l\"> In readelf und objdump wurde die M\u00f6glichkeit implementiert, den Inhalt der Abschnitte '.debug_sup' anzuzeigen, und standardm\u00e4\u00dfig werden Links zu einzelnen Dateien mit Debug-Informationen erlaubt.    <\/ul>\n<p>Quelle: <a
