Возрастание времени компиляции со временем :-)

[yoricI]

Здравия!
Всё понятно, код усложняется, строки прибывают, компиляторы взрослеют, и т.д. Но как так могло в пределах одной версии скакнуть?

Машинка сильно слабая у меня? Что-то стало напрягать в последнее время, за ночь, бывает, не укладывается :-(

[Vascom]

Похоже на действие заплаток для уязвимостей интела.

[yoricI]

У меня AMD, да и на другие не повлияло же.

[serzh-z]

Но как так могло в пределах одной версии скакнуть?

Может USE-флаги новые включили? Ну и genloop, возможно, суммирует время всех пересборок.

[yoricI]

Нет, флаги не включал. genloop показывает конкретно по времени каждую пересборку. Мистика.

[Vascom]

Всё же попробуй с mitigations=off.

[azsx]

Что-то стало напрягать в последнее время

а почему не поставить бинарные сборки? Раз напрягает.

[yoricI]

сё же попробуй с mitigations=off.

А по логам как оно у меня?

Вижу, что тоже после 5.11 резкое возрастание времени.

А как вот это понять, почему резкие колебания, и в сторону уменьшения в том числе? Что-то могло одновременно делаться на компе, но не настолько же?

Ну, это вечная пересборка и эксперименты с ccache
А насчёт одновременности - у меня запросто ещё и виртуалка может быть запущена вместе со сборкой.

Возможно, действительно после dev-qt/qtwebengine 5.11 при переходе на 5.12 был включен какой-то флаг, по требованию системы, конечно же, (возможно, что и из-за уникального пакета, установленного у меня, которого у других нет).
Хотя вряд ли, т.к.:
$ cat /etc/portage/package.use/dev-qt >=dev-qt/qtwebchannel-5.6.1 qml >=dev-qt/qtwebengine-5.6.1 widgets >=dev-qt/qtsingleapplication-2.6.1_p20150629 qt5 >=dev-qt/qtlockedfile-2.4.1_p20150629 qt5 $ ls -l /etc/portage/package.use/dev-qt -rw-r--r-- 1 root root 158 мая 8 2019 /etc/portage/package.use/dev-qt
Так что приходится считать, что что-то другое изменилось, или сам этот qt или компилятор, например.
