arm26目录支持早期使用26位地址的arm处理器. arm目录支持使用32位地址的arm处理器. arm系统结构中armv1, armv2都只支持26位地址.
从armv3到现在armv7(Cortex)支持32位地址.
从别处看到的,分享下!!
关于arm架构的一些核心文件,
armv与armo的区别,
跟arm26和arm文件夹的区别有点相同。
armo代表的是26位arm处理器。
armv代表的是32位arm处理器。
armo and armv
Throughout the ARM architecture core directories you will find both
-armv and -armo versions of some files.These indicate variants for the
ARM processors 26-bit mode and 32-bit mode.The 26-bit mode is in
the process of being phased out of ARM CPU designs and is only used
in a few early machines which predate the existence of the 32-bit
mode (e.g. the A5000, which has an ARM3 CPU).
The suffixes have the following meaning:
• armo is for 26-bit stuff;
• armv is for 32-bit stuff.
