Habr[Перевод] Процессоры ARM: смешиваем NEON с SVE — и забава, и пользаБольшинство мобильных устройств используют 64‑битные ARM‑процессоры. Однако они все заметнее и на серверах. Их число неуклонно растет, и все больше компаний, включая таких гигантов, как Amazon и Microsoft, также переходят на 64‑битные ARM. У этих процессоров есть специальные инструкции — ARM NEON. Они обеспечивают параллелизм, известный как SIDM — Single Instruction, Multiple Data, то есть «Инструкция одна, данных множество». Например, можно сравнить шестнадцать одних значений с шестнадцатью других с помощью всего одной такой инструкции. Некоторые из самых последних процессоров ARM также поддерживают еще более продвинутый набор команд — SVE, Scalable Vector Extension, или «Масштабируемое векторное расширение». Прогресс не останавливается — и вот уже появились спецификации SVE 2 и SVE 2.1.<a href="https://habr.com/ru/companies/selectel/articles/904420/" rel="nofollow noopener" translate="no" target="_blank">https://habr.com/ru/companies/selectel/articles/904420/</a><a href="https://zhub.link/tags/selectel" class="mention hashtag" rel="nofollow noopener" target="_blank">#selectel</a> <a href="https://zhub.link/tags/arm" class="mention hashtag" rel="nofollow noopener" target="_blank">#arm</a> <a href="https://zhub.link/tags/arm_neon" class="mention hashtag" rel="nofollow noopener" target="_blank">#arm_neon</a> <a href="https://zhub.link/tags/arm_sve" class="mention hashtag" rel="nofollow noopener" target="_blank">#arm_sve</a> <a href="https://zhub.link/tags/clang" class="mention hashtag" rel="nofollow noopener" target="_blank">#clang</a> <a href="https://zhub.link/tags/%D0%B0%D1%81%D1%81%D0%B5%D0%BC%D0%B1%D0%BB%D0%B5%D1%80" class="mention hashtag" rel="nofollow noopener" target="_blank">#ассемблер</a>

BenBEIs there a way to get Clang to output the exact number of constexpr evaluation steps it took while evaluating an initializer? AFAICS -ftime-trace only reports the time it took, not the evaluation steps counted against the evaluation step limit.Use-case: I have some constexpr-heavy C++ code I want to optimize to work with fewer constexpr evals when compiling, so you can do more of the operations of that lib at compile time …<a href="https://social.chaotikum.org/tags/clang" class="mention hashtag" rel="nofollow noopener" target="_blank">#clang</a> <a href="https://social.chaotikum.org/tags/cpp20" class="mention hashtag" rel="nofollow noopener" target="_blank">#cpp20</a>

HabrРазрабатываем собственный анализатор C++ программы в виде плагина для ClangЕсть много проектов, целью которых является превратить С++ более "безопасный" язык программирования. Но внесение изменений в синтаксис языка обычно нарушает обратную совместимость со старым кодом, который был написан до этого. Недавно вышла новая версия библиотеки memsafe для языка С++, которая превращает его в Rust с помощью плагина Clang добавляет в С++ безопасное управление динамической памятью и контроль инвалидации ссылочных типов данных во время компиляции приложения. Но данная статья не о библиотеке, а об особенностях разработки анализатора программы на С++ в виде плагина для Clang. Можно считать, что это подведение итогов по результатам сравнения нескольких разных способов создания плагина для компилятора С++ , а так же очередной Хабрахак для хранения результатов экспериментов и публикации итоговых выводов, которые я решил сохранить не только для себя, но и в виде статьи на Хабре, что бы результатами моего труда могли воспользоваться и другие хорошие люди :-), которым так же может потребоваться погрузиться в дебри парсинга исходного текста программ.<a href="https://habr.com/ru/articles/900224/" rel="nofollow noopener" translate="no" target="_blank">https://habr.com/ru/articles/900224/</a><a href="https://zhub.link/tags/clang" class="mention hashtag" rel="nofollow noopener" target="_blank">#clang</a> <a href="https://zhub.link/tags/clangquery" class="mention hashtag" rel="nofollow noopener" target="_blank">#clangquery</a> <a href="https://zhub.link/tags/plugin" class="mention hashtag" rel="nofollow noopener" target="_blank">#plugin</a> <a href="https://zhub.link/tags/memsafe" class="mention hashtag" rel="nofollow noopener" target="_blank">#memsafe</a> <a href="https://zhub.link/tags/c" class="mention hashtag" rel="nofollow noopener" target="_blank">#c</a>++ <a href="https://zhub.link/tags/attribute" class="mention hashtag" rel="nofollow noopener" target="_blank">#attribute</a>
