Hi panxiaohe,
> Hello, the results of "as" command are not consistent in arm and x86.

> May I ask why does it have different values in arm and x86？
Because accepting -V as an alternative to the -v option is an x86 specific
feature. In particular -V is supported by the x86 assembler because the same
option is supported by the old SVR4 assembler. Ie this is a backwards
compatibility feature.
The AArch64 assembler does not need to be backwards compatible with earlier
assemblers (there are none) and so it does not support the -V option.
Note that both assemblers do support -v and --version.
