ucontext function have bug in arm version
#include <sys/ucontext.h> in this header defined ucontext related type and function(such as ucontext_t, getcontext, makecontext, and swapcontext). It works fine in rosetta mode, but failed on native arm, cause the swap param's address is wrong. I confirmed it by using an open source developed for iOS(https://github.com/MCApollo/libucontext-ios-arm64) support functions. Hope this bug can be fixed in future, cause a lot of unix type open source depend on it, and may cause m1 native version adapt slow.

Safari low performance on special js web content.
When view some special web content with js, as mentioned below(with right corner on "Continue",which showed in Chinese, you can refer the arrow, let it auto scroll will show the problem). Cause P-core to increase to more 100% cpu usage. The page is test under windows; under chrome on same OS environments, no problem. But on safari 15.6(macOS 12.5, m1 Mac mini), 16beta and tech preview always have the same issue. https://www.baidu.com/s?rsv_idx=1&wd=%E9%87%8D%E5%BA%86%E5%9F%8E%E5%8F%A3%E5%8E%BF%E5%9F%8E%E4%BE%9B%E6%B0%B4%E6%B0%B4%E6%BA%90%E4%BB%85%E5%A4%9F%E6%94%AF%E6%92%91%E5%8D%81%E5%A4%A9&fenlei=256&ie=utf-8&rsv_pq=c3e520bf0006d8d0&oq=%E5%9B%9B%E5%B7%9D%E5%B0%8F%E4%BC%99%E9%AB%98%E6%B8%A9%E5%A4%A9%E5%8D%96%E5%86%B0%E5%9D%97%E6%97%A5%E5%85%A5%E8%BF%87%E4%B8%87&rsv_t=1b91DUeCY7TbON4DYyf9mO8Ujl1zg9wmPQ0O%2BRUbRNO%2F3g42IBRjUsYmELE&rqid=c3e520bf0006d8d0&rsf=526d5fb04211f1d3aefdb673067d9d32_1_15_7&rsv_dl=0_right_fyb_pchot_20811&sa=0_right_fyb_pchot_20811

Embed framework will affect archive upload's Re-sign selection
Normally, after archive, after click Distrubute App, there will be a window called "Re-sign ***". And the window will offer two selections include: "Automatically manage signing" and "Manually manage signing". But once my project contains some embed frameworks in project(first two in image 2, WebRTC related framework is managed by pods), when distribute in organizer, there will not show selection window, and go directly to Manually manage signing window. My project also contains pods to manage other code, and I do not know it is related. Is this a bug or something, hope someone can fix this, cause manually manage code sign is not a good exp.
