インテルではuname -m
、OSが32ビットであるか64ビットであるかを知るために結果を見ることができますが、ARMでは次のようになります。
armv7l
から推測した
file /usr/bin/ls
32ビットOSを使用していますが、これをもっと簡単に知る方法はありますか?
uname -a
and の出力は何gcc -v
ですか?役に立つかもしれません。
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.
