什么是armv7s? [英] What is armv7s?

问题描述

这似乎是较新XCode中的新选项-在有效体系结构下，而不是"armv6 armv7"，我现在看到的是"armv7 armv7s".什么是armv7s，我需要为它以及armv7进行构建吗?

This seems to be a new option in newer XCode - instead of "armv6 armv7" under Valid architectures I now see "armv7 armv7s". What is armv7s and do I need to build for it as well as armv7?

推荐答案

iPhone 5将随附并仅运行iOS 6.0.为配合iOS 6.0的发布，Apple为开发人员播种了较新版本的开发工具. Xcode 4.5进行了两项重大更改:放弃了对ARMv6 ISA(由iPhone 2G和iPhone 3G中的ARM11内核使用)的支持，保留了对ARMv7(由现代ARM内核使用的)的支持，并增加了对设计的新架构目标的支持.支持新的A6 SoC:armv7s.

The iPhone 5 will ship with and only run iOS 6.0. To coincide with the launch of iOS 6.0, Apple has seeded developers with a newer version of its development tools. Xcode 4.5 makes two major changes: it drops support for the ARMv6 ISA (used by the ARM11 core in the iPhone 2G and iPhone 3G), keeps support for ARMv7 (used by modern ARM cores) and it adds support for a new architecture target designed to support the new A6 SoC: armv7s.
