If not it's going to be one of those architectural liabilities that's irritating to fix. \r\n\r\nSomehow I missed the tagged memory that came in in v8.5. Tagged architectures are always interesting, though this is a _very_ limited tagging setup that seems to just do reference liveness.<\/div><p><span>Today, as part of Arm&rsquo;s Vision Day event, the company is announcing the first details of the company&rsquo;s new Armv9 architecture, setting the foundation for what Arm hopes to be the computing platform for the next 300 billion chips in the next decade.<\/span><\/p>\n<p align=\"center\"><a href=\"http:\/\/dynamic1.anandtech.com\/www\/delivery\/ck.php?n=a1f2f01f&amp;cb=50349024\"  rel=\"noopener noreferrer\"><img src=\"http:\/\/dynamic1.anandtech.com\/www\/delivery\/avw.php?zoneid=24&amp;cb=50349024&amp;n=a1f2f01f\" border=\"0\" alt=\"\" referrerpolicy=\"no-referrer\" loading=\"lazy\"\/><\/a><img src=\"http:\/\/toptenreviews.122.2o7.net\/b\/ss\/tmn-test\/1\/H.27.3--NS\/0\" border=\"0\" alt=\"\" referrerpolicy=\"no-referrer\" loading=\"lazy\"\/><\/p>","protected":false},"excerpt":{"rendered":"<p>Today, as part of Arm\u2019s Vision Day event, the company is announcing the first details of the &#8230;<\/p>\n<p> <a href=\"https:\/\/pappp.net\/?p=38671\">Continue reading <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[226],"tags":[],"class_list":["post-38671","post","type-post","status-publish","format-standard","hentry","category-news-2"],"_links":{"self":[{"href":"https:\/\/pappp.net\/index.php?rest_route=\/wp\/v2\/posts\/38671","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pappp.net\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/pappp.net\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/pappp.net\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/pappp.net\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=38671"}],"version-history":[{"count":0,"href":"https:\/\/pappp.net\/index.php?rest_route=\/wp\/v2\/posts\/38671\/revisions"}],"wp:attachment":[{"href":"https:\/\/pappp.net\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=38671"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/pappp.net\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=38671"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/pappp.net\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=38671"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
