Are armv8 and arm64 the same?
提问by hasan
In xcode which is the developement environment for iOS. When creating a new project. Build settings states that it supports armv7, armv7sand arm64architectures.
在 iOS 的开发环境 xcode 中。创建新项目时。构建设置表明它支持armv7、armv7s和arm64架构。
The following chart shows apple devices architectures:
下图显示了苹果设备的架构：
armv8not mentioned anywhere. Does that mean armv8and arm64is the same thing?
armv8未在任何地方提及。这是否意味着armv8和arm64是一回事？
I wonna use the following binary: http://www.libjpeg-turbo.org/Documentation/OfficialBinaries
我不会使用以下二进制文件：http: //www.libjpeg-turbo.org/Documentation/OfficialBinaries
It says that version 1.5.1 of this binary supports armv8 architecture. That also indicates that armv8 and arm64 are the same thing.
它说这个二进制文件的 1.5.1 版支持 armv8 架构。这也表明 armv8 和 arm64 是一回事。
Another question but about the binary. Does the link indicates that its safe to use the 1.5.1 version for iOS?
另一个关于二进制的问题。该链接是否表明可以安全地使用 iOS 1.5.1 版本？

Oh, ambiguous terminology - "architecture" in this context doesn't actually mean architecture in the sense of the ISA or system architecture laid down by ARM, what it really means is "iOS target", i.e. a particular system configuration and level of ISA support:
哦，模棱两可的术语——这里的“架构”实际上并不是指 ISA 意义上的架构或 ARM 制定的系统架构，它真正的意思是“iOS 目标”，即特定的系统配置和 ISA 级别支持：
- "armv7" represents a certain configuration of the ARMv7-A architecture.
- "armv7s" represents a slightly different configuration of the ARMv7-A architecture, with more optional features present over the base "armv7" target.
- "arm64" represents the AArch64 state of the ARMv8-A architecture; there is no "armv8" target.
- “armv7”代表ARMv7-A架构的某种配置。
- “armv7s”代表了 ARMv7-A 架构的一个稍微不同的配置，在基本的“armv7”目标上有更多的可选功能。
- “arm64”代表ARMv8-A架构的AArch64状态；没有“armv8”目标。
