我知道我可以在intel下查看结果,uname -m
以了解我的操作系统是32位还是64位,但是在ARM下,这样做可以:
armv7l
我从
file /usr/bin/ls
我使用的是32位操作系统,但是如何以更简单的方式知道这一点?
uname -a
and 的输出是gcc -v
什么?这些可能会有所帮助。
Announced October 2011, ARMv8-A (often called ARMv8 although not all variants are 64-bit such as ARMv8-R) represents a fundamental change to the ARM architecture. It adds a 64-bit architecture, named "AArch64", and a new "A64" instruction set. AArch64 provides user-space compatibility with ARMv7-A ISA, the 32-bit architecture, therein referred to as "AArch32" and the old 32-bit instruction set, now named "A32" ARM announced their Cortex-A53 and Cortex-A57 cores on 30 October 2012.
